Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It is to be noted that, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

For the sharing of important data needing to be kept secret, the data is usually shared on another terminal device after being copied from a computer, a tablet, a smart phone or other terminal devices which are cut off an external network through a USB flash disk, a mobile hard disk or other mobile storage devices. However, when the mobile storage device such as a usb disk or a mobile hard disk shares data on the terminal device, a trace of data transmission may be left. In this way, when the terminal device is connected to the internet again, a hacker can know the contents of the transmitted important data, such as a commercial secret or a technical secret, through the trace of data transmission. In addition, if the terminal device or the mobile storage device is lost, external personnel can also obtain the contents of the transmitted important data through the trace left by the data transmission port of the terminal device, obtain the contents of the important data directly obtained by the picked mobile storage device, so that the leakage of the important data is caused, and the data security is still vulnerable to great threat.
In one embodiment, in order to solve the problem of low security of data transmission in the conventional hardware storage method of electronic storage, as shown in fig. 1, a mobile storage device 100 is provided, which includes a housing 12, and an encryption/decryption module 14, a sliding switch module 16, a data plug 18 and a data socket 19 respectively mounted on the housing 12. The encryption and decryption module 14 is electrically connected to the sliding switch module 16, the data plug 18 and the data socket 19, respectively. The encryption and decryption module 14 is used for encrypting and storing the input data to be stored and decrypting the output stored data. The sliding switch module 16 is used for switching the on and off states of the encryption and decryption module 14 and switching the data input and output states of the encryption and decryption module 14. The data plug 18 and the data socket 19 are used for transmitting data to be stored and decrypted stored data.
It will be appreciated that the housing 12 described above may be a plastic housing 12, a metal housing 12, or a carbon fiber housing 12 of various geometries for housing and shielding the various electronic components of the mobile storage device 100. The housing 12 may be an integrally formed housing 12 or may be a removable modular housing 12, such as a housing 12 formed by assembling two or more components (housing assemblies). The shape, size, material, etc. of the housing 12 may be determined according to the requirements of the electronic component mounting, protection, portability, etc. in practical applications, as long as each electronic component of the mobile storage device 100 can be effectively mounted and protected. The dashed connections in fig. 1 represent electrical connections. The dotted line portion of the element indicates a structural portion provided inside the case 12.
The components such as the encryption/decryption module 14, the sliding switch module 16, the data plug 18, and the data socket 19 may be disposed on the outer surface of the housing 12, and some components may be disposed in the accommodating cavity formed by the housing 12, or some components may be embedded in the housing 12; for example, but not limited to, the encryption/decryption module 14 and the sliding switch module 16 are installed on the outer surface of the housing 12, the data plug 18 and the data socket 19 are installed in the accommodating cavity of the housing 12, the data plug 18 extends out of the outer surface of the housing 12, the jack of the data socket 19 faces one side of the outer surface of the housing 12, and the specific installation manner and installation position can be determined according to the shape and size of each electronic component, the loading fixing and protection effect required by each electronic component, and the like. The data plug 18 and the data receptacle 19 may each be a data transfer port conventional in the art, such as, but not limited to, a data plug 18 and a data receptacle 19 of the type-c interface or of the USB interface type of each version. The data plug 18 and the data socket 19 may be disposed on the housing 12 in a symmetrical manner or in an asymmetrical manner, as long as the mobile storage device 100 can be reliably connected to another mobile storage device 100 or terminal device of the same type.
The encryption/decryption module 14 is a module composed of digital encryption/decryption circuit modules or devices known in the art and a data storage device conventional in the art. The encryption and decryption circuit module or device is an encryption and decryption module or device in an input form such as, but not limited to, a dial input, a touch input, a key input, or the like. The sliding switch module 16 may be any type of sliding switch in the art, as long as it can control the start and stop of the encryption/decryption module 14 and the data input/output state switching. The encryption and decryption module 14, the sliding switch module 16, the data plug 18 and the data socket 19 are electrically connected through metal wires, or through a PCB, so as to realize connection through a printed circuit on the PCB, and specifically, can be selected according to the requirements of practical application.
Specifically, the mobile storage device 100 can access the terminal device storing important data through the data plug 18, and copy the important data to be shared from the terminal device. The operation of the sliding switch module 16 can be used to switch the encryption/decryption module 14 to the data encryption operating state, and select the current data transmission state of the encryption/decryption module 14 as the input state. Thereafter, the important data to be shared can be input through the data plug 18, and the encryption and decryption module 14 performs encryption processing, for example, the encryption and decryption module 14 completes encryption processing on the input important data according to the encryption password input by manual operation, and then stores the encrypted data. After the data copying is completed, the encryption and decryption module 14 can exit the encryption working state through the operation of the sliding switch module 16, and the current data transmission state is converted from the input state to the non-input-output latch state. Thus, the terminal device cannot continue to input data into the mobile storage device 100, and the important data stored in the mobile storage device 100 cannot be output to the outside.
When important data stored in the mobile storage device 100 needs to be shared, the data plug 18 of another mobile storage device 100 (hereinafter referred to as a target device for convenience of differentiation and explanation) that needs to acquire the important data may be plugged into the data socket 19 of the mobile storage device 100 (hereinafter referred to as a source device for convenience of differentiation and explanation) that has stored the important data. It is understood that the data plug 18 of the source device may be plugged into the data jack 19 of the target device, and the corresponding subsequent input/output operations may be similarly understood. After the two mobile storage devices 100 are connected, the operation can be performed on the sliding switch module 16 of the source device, the working state of the source device is switched to be on, and the data transmission state of the encryption and decryption module 14 of the source device is switched to be in a data output state; correspondingly, the sliding switch module 16 of the target device is operated to switch the working state of the target device to on, and switch the data transmission state of the encryption and decryption module 14 of the target device to the data input state.
Thus, the encryption/decryption module 14 of the source device can decrypt the stored and encrypted important data and output the decrypted important data to the data plug 18 of the destination device through the data jack 19 by inputting the encryption password used for encryption to the encryption/decryption module 14 of the source device. Correspondingly, the encryption and decryption module 14 of the target device inputs the encryption password required to be adopted, and the encryption and decryption module 14 of the target device can encrypt and automatically store the important data input from the data plug 18 according to the input encryption password. After the important data is transmitted, the respective encryption/decryption modules 14 exit the decryption/encryption working state through the operation of the sliding switch modules 16 of the source device and the target device, and the respective current data transmission state is converted from the output/input state to the non-input/output latching state, so that the sharing of the important data can be completed.
The mobile storage device forms a brand new mobile storage device through the combination design of the shell 12, the encryption and decryption module 14, the sliding switch module 16, the gear switch, the data plug 18 and the data socket 19. When data sharing is performed, the data plug 18 can be directly inserted into a data socket 19 of another mobile storage device of the same type, the sliding switch module 16 of each mobile storage device controls the starting of the encryption and decryption module 14, and the control of the encryption and decryption module 14 on the data input and output states is switched. The encryption and decryption module 14 of the mobile storage device sharing data decrypts the stored data to be output, and outputs the decrypted data to the data plug 18 (or the data socket 19) of the mobile storage device receiving the data through the data socket 19 (or the data plug 18); the encryption/decryption module 14 of the mobile storage device receiving the data can encrypt and store the input data to be stored. The data sharing process does not need to pass through a computer terminal, so that the data transmission safety is greatly improved, and the convenience of data confidential transmission is greatly improved.
In one embodiment, as shown in FIG. 2, the slide switch module 16 includes a toggle button 162, a slide rail 164, an input gear 166, an output gear 168, and a neutral gear 169. The toggle button 162 is disposed to match the position of the slide rail 164. The slide rails 164 are mechanically connected to the housing 12. The input gear 166, the output gear 168, and the neutral gear 169 are respectively provided on the slide rail 164. The toggle button 162, the input gear 166, the output gear 168 and the neutral gear 169 are electrically connected to the encryption/decryption module 14, respectively. The toggle button 162 is used for sliding on the slide rail 164 to trigger the input gear 166, the output gear 168 and the idle gear 169, and controlling the switching between the open state and the closed state of the encryption/decryption module 14. The input gear 166 is used for controlling the encryption/decryption module 14 to receive data to be stored. The output stage 168 is used for controlling the encryption/decryption module 14 to output the stored data. The idle gear 169 is used to control the encryption/decryption module 14 to enter a data latching state.
It will be appreciated that the slide rails 164 may be male or female insulated rails as is conventional in the art. Each gear is distributed on the sliding rail 164, and the specific position can be determined according to the need of triggering each gear when the toggle button 162 slides on the sliding rail 164. The distribution mode of each gear on the sliding rail 164 may be equal-distance uniform distribution or unequal-distance non-uniform distribution, as long as the gear can be effectively triggered by the sliding of the toggle button 162.
Toggle button 162 can be an independent start stop switch button, for example, toggle or press toggle button 162 alone can realize starting stop switch's state switch, and need not to realize starting stop switch's state switch with the direct contact of gear. Toggle button 162 also can be with each gear piece cooperation realize that encryption decryption module 14 opens and stops the non-independent shift knob that control realized gear selection simultaneously, for example toggle button 162 slides to gear piece department on slide rail 164, when toggle button 162 is stirred or is pressed, toggle button 162's metal plectrum realizes encryption decryption module 14 and opens the gear selection that the control realized current contact gear piece simultaneously with the gear piece joint. Correspondingly, each gear can be an independent gear switch, the toggle button 162 slides on the slide rail 164 to any gear, and the toggle button 162 triggers the state of the gear switch through direct contact or non-contact induction triggering and the like. Each gear component may also be a metal conductive sheet separately disposed on the sliding rail 164, and is used to cooperate with the toggle button 162 to realize gear selection. The toggle button 162 and each gear member may be a switch component made of the same type of metal conductive sheet (e.g., copper sheet, aluminum sheet, platinum sheet, or other conductive sheet), or may be different types of metal conductive sheets, which may be specifically selected according to actual application occasions and design costs.
The mechanical connection between the sliding rails 164 and the housing 12 may be welding, bonding, clipping or other connection methods as long as the sliding rails 164 can be firmly mounted on the housing 12. The arrangement of each gear on the slide rail 164 may be bonding, clamping or other arrangement, as long as each gear can be stably installed on the slide rail 164. The arrangement order of the shift elements on the slide rail 164 may be the arrangement order of the input shift element 166, the output shift element 168 to the neutral shift element 169, the arrangement order of the input shift element 166, the neutral shift element 169 to the output shift element 168, the arrangement order of the neutral shift element 169, the arrangement order of the input shift element 166 to the output shift element 168, or other arrangement orders, and may be specifically determined according to the matching requirement of the slide trigger with the toggle button 162, as long as the switching of the data input/output and latch states can be accurately realized.
Specifically, the selection triggering of different gears can be realized by sliding the toggle button 162 on the slide rail 164. For example, the shift position corresponding to the output shift position 168 is the T-position, the shift position corresponding to the input shift position 166 is the R-position, and the shift position corresponding to the neutral shift position 169 is the N-position. When the mobile storage device 100 does not share data with other terminal devices or the mobile storage device 100, the toggle button 162 can be slid to the N-position, at this time, the data stored in the encryption and decryption module 14 cannot be output externally, the external data cannot be input into the encryption and decryption module 14, and the encryption and decryption module 14 can exit the working state by toggling or pressing the toggle button 162. When the mobile storage device 100 needs to share data with other terminal devices or the mobile storage device 100, the toggle button 162 may be slid to the T-position, and after the toggle button 162 is toggled or pressed, the data stored in the encryption and decryption module 14 may be decrypted and then output to the outside, and the external data may not be input to the encryption and decryption module 14; after the data sharing is completed, the data output state can be exited by dialing or pressing the toggle button 162 again. When the mobile storage device 100 needs to receive data shared by other terminal devices or the mobile storage device 100, the toggle button 162 may be slid to the R-range, and after the toggle button 162 is toggled or pressed, the data stored by the encryption and decryption module 14 cannot be output externally, and external data may be input into the encryption and decryption module 14 and encrypted for storage; after the data is received, the data input state can be exited by dialing or pressing the toggle button 162 again.
Through the arrangement mode of the toggle button 162 and the gear pieces on the slide rail 164, the switching of states such as different data input and output of the mobile storage device 100 can be effectively realized, and the safety of the data storage and sharing process is effectively improved.
In one embodiment, as shown in fig. 2, the slide 164 is a concave slide 164. The toggle button 162 is a copper button. The input gear 166, the output gear 168 and the idle gear 169 are all copper sheets.
It can be understood that, in this embodiment, the concave slide rail 164 is adopted to provide the toggle button 162 and each gear, the toggle button 162 can slide in the sliding slot of the concave slide rail 164, and the reliability of the limiting is better, so that the stability of the toggle button 162 on the housing 12 can be further improved. The copper sheet button refers to a button which adopts a copper sheet as a metal conducting sheet, and the button generally comprises the copper sheet and a button component.
Specifically, in this embodiment, each gear is made of a copper sheet, and the toggle button 162 is made of a copper sheet button, each copper sheet is directly electrically connected to the encryption/decryption module 14, or indirectly electrically connected to the encryption/decryption module 14 through a printed circuit of the PCB substrate or other intermediate auxiliary components, so as to implement switching of the on/off state and switching of the data input/output state of the encryption/decryption module 14.

Inside the housing 12, i.e. inside the accommodating cavity of the housing 12, the encryption and decryption control unit 144 and the data storage unit 146 are respectively directly or indirectly mechanically connected to the inner surface of the housing 12 (i.e. the surface of the housing 12 close to the accommodating cavity side), so as to realize the limiting fixation. The encryption and decryption control unit 144 and the data storage unit 146 may be respectively and independently disposed in the accommodating cavity of the housing 12, or may be mounted on the same PCB substrate to achieve a unified configuration.
Specifically, after the encryption/decryption control unit 144 is set to enter the encryption/decryption operating state through the slide switch module 16 and a corresponding data input or output state is selected, the encryption/decryption control unit 144 is provided with an encryption password through the operation input unit 142, and the encryption/decryption control unit 144 can encrypt data input into the data storage unit 146 from the data socket 19 or the data plug 18, or decrypt stored data output from the data storage unit 146 and output the encrypted data to the outside through the data socket 19 or the data plug 18.

In one embodiment, as shown in fig. 4, the operation input unit 142 includes a key substrate 1422 and a number of number keys 1424. The key substrate 1422 is mechanically matched to each of the number keys 1424. The key substrate 1422 is mechanically coupled to the housing 12.

The key substrate 1422 is an electronic pressing board that cooperates with the number keys 1424, and the number of key contacts included on the key substrate 1422 is determined according to the number of the number keys 1424.

In the previous embodiments, the number keys 1424 may be mechanically connected to the outer surface of the housing 12 directly through the key substrate 1422. In this embodiment, each number key 1424 may be embedded in the outer surface of the housing 12, so that the pressing operation portion of each number key 1424 extends out of the outer surface of the housing 12, and the whole number key 1424 does not protrude from the outer surface of the housing 12, thereby increasing the stability of each number key 1424 and reducing the probability of key falling. Each numeric key 1424 is movable relative to the housing 12 when pressed to enter an encrypted password.
Specifically, when the toggle button 162 is slid to the input position or the output position and the toggle button 162 is pressed, the encryption/decryption control unit 144 enters the encryption/decryption operating state and is switched to the data input or output state. At this time, after the corresponding number key 1424 is pressed to input the encrypted password, the input encrypted password is converted into a corresponding electrical signal through the key substrate 1422 and is output to the encryption and decryption control unit 144, so as to complete the input of the encrypted password. Thereafter, the encryption/decryption control unit 144 may encrypt the input data according to the input encryption password or decrypt the output data.

It is understood that the USB plug and the USB socket may be mechanically connected to the housing 12 by screws, welding, bonding, clipping, or other connecting methods, as long as the USB plug and the USB socket can be stably mounted on the housing 12. The USB plug may protrude out of the outer surface of the housing 12, and a corresponding USB socket may be embedded in the accommodating cavity of the housing 12, and the socket is flush with the outer surface of the housing 12, or the socket partially extends to the outer surface of the housing 12, and the specific mounting structure may be determined according to the needs of practical applications.
The USB plug and the USB socket are disposed on the housing 12 in a positionally opposite manner, which means that the USB plug and the USB socket are disposed in a manner symmetrically distributed along the axial direction of the housing 12, or in a manner symmetrically distributed along the radial direction of the housing 12. For example, when the casing 12 is a cylindrical casing 12, the overall shape of the entire mobile storage device 100 is cylindrical, and the USB plug and the USB socket are located at two axial ends of the casing 12. Through the above-mentioned position setting mode of the USB plug and the USB socket on the casing 12, the mobile storage device 100 can be conveniently plugged with other terminal devices or the mobile storage device 100, and the use efficiency of the mobile storage device 100 is effectively improved.

It is understood that the indicator light may be an LED indicator light, a laser indicator light, or other type of indicator light, as long as the indication of different encryption/decryption states can be realized by the flashing of the lamp tube or the lamp tubes with different colors. The number of the indicator lights may be one, for example, one indicator light that can emit light of one or more colors, or two or more, and may be specifically determined according to various encryption/decryption states indicated by the required distinction, for example, a light on or a light on yellow indicates that the encryption/decryption control unit 144 is activated, a light on green or a light on blinking green indicates that the password input is correctly encrypted/decrypted, a light on or a light on red indicates that the password is wrong (error alarm), a light off indicates that a non-data transmission state is output, and the like.
The indicator light is mounted on the outer surface of the housing 12, and the specific position can be determined according to the overall shape and the use mode of the mobile storage device 100, so long as the current encryption and decryption state of the user can be reminded in a striking manner. Through the setting of pilot lamp, can the present encryption and decryption state of visual indication encryption and decryption module 14, convenient to use person learns the current operating condition who is located of mobile storage equipment 100 in real time to further improve the availability factor of mobile storage equipment 100.
In an embodiment, as shown in fig. 5, in order to more clearly illustrate the above-mentioned mobile storage device 100 and to facilitate understanding of the above-mentioned embodiments, the following description is applied by taking an application scenario of data transmission between two mobile storage devices 100 of the same type as an example:
before data sharing is carried out, both the source equipment and the target equipment are set to be N gears. And inserting the USB plug of the target equipment into the USB socket of the source equipment to realize USB interface connection. The target device is set to be in an R file to be switched to a data input state, the source device is set to be in a T file (and an encryption password is input, which is a scene when encryption and decryption are needed) to be switched to a data output state, and data are shared to the target device from the source device until data transmission is completed. And setting the source equipment and the target equipment to be N-gear, and pulling the target equipment out of the source equipment.
In an embodiment, as shown in fig. 6 and fig. 7, a data encryption processing method is further provided, which is described by taking the method as an example for being applied to the above-mentioned mobile storage device 100, and includes the following steps S12 to S18:
and S12, collecting input data to be stored and receiving input encryption operation signals.
The encryption operation signal is an operation signal generated by the encryption/decryption module when the user operates the encryption/decryption module of the mobile storage device 100 to input the encryption password. For example, when a user sequentially presses down the encryption and decryption module or inputs an encryption password by touching a digital key (which may be a mechanical key or a virtual key on a touch screen), an encryption signal generated by the encryption and decryption module is input correspondingly, so that the encryption and decryption module can obtain the currently input encryption password.
Specifically, after the user operation slide switch module in order to start the encryption and decryption module, the encryption and decryption module begins to gather the data of treating the storage from data plug or data socket input promptly to the encryption and decryption module receives corresponding encryption operating signal when the user inputs the encryption password, so that acquire the encryption password of input.
And S14, determining the length of the encryption password according to the encryption operation signal, and equally dividing the data to be stored according to the length of the encryption password.
The length of the encryption password refers to the length of the input password, for example, the number of times that a user presses or touches a digital key on the encryption and decryption module is the length of the encryption password.
Specifically, the encryption and decryption module equally divides the acquired data to be stored according to the length of the encryption password to obtain the data to be stored corresponding to the length of the encryption password. For example, if the number of times of pressing or touching the numeric key is 7 times (or 6 or 9 times, which can be understood in the same way), the collected data to be stored is divided into 7 pieces on average.
And S16, distributing different data labels for the divided data to be stored respectively, associating the data labels with the input sequence of the encryption password, and determining the key labels of the data to be stored.
The data tags are unique marks corresponding to the respective data to be stored one by one, for example, but not limited to, 7 data to be stored are respectively assigned data tags a/B/C/D/E/F/G, and a tag in which letters and numbers are mixed or tags in other forms may be used as long as the data tags can uniquely mark the respective data to be stored. The input sequence of the encryption password refers to the sequence of pressing or touching the number keys on the encryption/decryption module by the user, such as 1/3/4/3/1/3/2 (i.e. the sequence of the triggered number keys).
Specifically, after the encryption and decryption module equally divides the acquired data to be stored, the data labels of the data to be stored are respectively set for the data to be stored, and then the data labels are associated with the input sequence of the encryption password so as to respectively set corresponding key labels for the data to be stored. As shown in fig. 7, for example, the input sequence of the encryption password is 1/3/4/3/1/3/2, and the data labels are a/B/C/D/E/F/G, respectively, so that the key labels of the data to be stored are a-1/B-3/C-4/D-3/E-1/F-3/G-2, respectively.
And S18, sequentially recombining the data to be stored according to the key labels, and sequentially rearranging the data to be stored according to the sequence of the key labels to obtain encrypted data.
Specifically, the encryption and decryption module sequentially recombines the data to be stored according to the key labels of the data to be stored, and the key labels are a-1/B-3/C-4/D-3/E-1/F-3/G-2, as shown in fig. 7, the combination result is 1-a/E, 2-G, 3-B/D/F, 4-C. Then, the encryption and decryption module rearranges the data to be stored after being recombined in sequence according to the sequence of the key labels, namely A/E/G/B/D/F/C. That is, according to the input sequence of the encryption password, the data to be stored are sequentially rearranged to obtain the encrypted whole data to be stored. It should be noted that the foregoing examples are merely illustrative, so as to facilitate understanding, and are not the only limitations of the present application, and a person skilled in the art may choose to assign different data labels according to the foregoing steps, so as to implement different key label settings. The encrypted data to be stored can be stored in the internal data storage unit 146, for example, the user operates the sliding switch module again to switch the encryption/decryption module to the off state, and the decrypted data is latched for carrying and sharing.
Above-mentioned data encryption processing method through being applied to foretell mobile storage device 100, realizes the encryption operation to input data in coordination with the encryption and decryption module, and the encryption operation is convenient and fast degree height and the encryption password sets up in a flexible way, and the encryption and decryption module can carry out corresponding data encryption for treating the storage data according to the encryption password of input, and encryption operating efficiency is high and the security is better, can effectively promote the security of data storage and transfer.
In an embodiment, as shown in fig. 8 and fig. 9, a data decryption processing method is further provided, which is described by taking the method as an example of being applied to the mobile storage device 100, and includes the following steps S21 to S27:
s21, reading the encrypted stored data and receiving the input decryption operation signal.
The decryption operation signal is an operation signal generated by the encryption and decryption module when the user operates the encryption and decryption module of the mobile storage device 100 to input the encrypted password. For example, when a user sequentially presses down the encryption and decryption module or inputs an encryption password by touching a digital key (which may be a mechanical key or a virtual key on a touch screen), a decryption signal generated by the encryption and decryption module is input correspondingly, so that the encryption and decryption module learns the currently input encryption password. Generally, the encryption password used in the decryption process and the encryption process are the same on the same mobile storage device 100. The encrypted stored data is the data after the data to be stored is encrypted.
Specifically, after a user operates the sliding switch module to start the encryption and decryption module, the encryption and decryption module starts to read stored data inside, namely the data which needs to be shared currently; the encryption and decryption module receives a corresponding decryption operation signal when a user inputs an encryption password so as to acquire the input encryption password.
And S23, determining whether the input encryption password is correct according to the decryption operation signal.
Specifically, when the user need share the already encrypted data output, need provide correct encryption password to the encryption and decryption module to make the encryption and decryption module decrypt and output the already encrypted data. And, the encryption and decryption module has obtained the original encryption password that uses when encrypting in the operation process, therefore, when the user inputs the encryption password so that the encryption and decryption module decrypts the data that have been deposited, the encryption and decryption module will be at first with the user current input encryption password and the original encryption password of input among the encryption process carry on the comparison, if two encryption passwords are unanimous, then the current input encryption password is correct, otherwise the current input encryption password is wrong.
When the encryption password is correct, the encryption and decryption module can normally perform subsequent data decryption output operation. When the encryption code is wrong, the encryption and decryption module can warn through the control indicator lamp, for example, the control indicator lamp is red. If the user inputs the encryption password for many times and is wrong, for example, 3 times or 5 times and the like, the encryption and decryption module can be automatically switched to a closed state to latch the stored data, the encryption password input operation can also be set to be an invalid state so that the user cannot continue to operate or the stored data can be directly destroyed, and the encryption and decryption module can be specifically set according to the actual application occasions, the confidentiality of the data and the like.
If so, S25 decomposes the stored data according to the length of the encryption password and the key labels of the stored data.
For explanation of the length of the encryption password and the key label, reference may be made to the corresponding explanation of the above data encryption processing method, and details will not be repeated here and below.
Specifically, after the encryption and decryption module verifies that the currently input encryption password is correct, the read stored data may be decomposed according to the length of the encryption password and each key label of the stored data, that is, the entire stored data is decomposed into the number of parts corresponding to the length of the encryption password, for example, the encryption password is 7 bits, the stored data is decomposed into 7 parts of data to be stored, taking the above-mentioned a-1/B-3/C-4/D-3/E-1/F-3/G-2 as an example, the decomposition process is as shown in fig. 9, and each part of the decomposed data to be stored is 1-a/E, 2-G, 3-B/D/F, or 4-C.
And S27, rearranging the decomposed data to be stored according to the input sequence of the encryption passwords associated with the key labels to obtain the decrypted data to be stored.
Specifically, the encryption and decryption module rearranges the data to be stored according to the sequence of the currently input encryption password, namely the input sequence of the encryption password used in the encryption process, and can obtain the whole accurate data to be stored: if the sequence of the input encryption passwords is 1/3/4/3/1/3/2, the whole data to be stored, which is formed by the data to be stored in the sequence of A/B/C/D/E/F/G, is the decrypted data to be stored. The decrypted data to be stored can be output through a data socket or a data plug.
Above-mentioned data decryption processing method, through being applied to foretell mobile storage device 100, the decryption operation to output data is realized to the encryption decryption module in coordination, and the simple degree of decryption operation is high, and the encryption decryption module can carry out corresponding data decryption for the data that have stored according to the encryption password of input, and the high and security of decryption operating efficiency is better, can effectively promote the security of data transfer.
In one embodiment, as shown in fig. 9, regarding the process of decomposing the stored data in step S25, the following processing steps may be further included:
if any key label corresponds to a plurality of data to be stored, extracting the previous data to be stored according to the distribution sequence of the data labels according to the input sequence of the encrypted password.
Specifically, in the data decryption process, if one key tag corresponds to multiple data tags of data to be stored, example 1 corresponds to two a/E data to be stored, and example 3 corresponds to three B/D/F data to be stored, the encryption and decryption module may strip and extract one data to be stored whose distribution sequence is prior in the current data decomposition process according to the input sequence of the encryption password in each data decomposition (the total number of rounds is determined by the total number of data to be stored) process. As shown in fig. 9, the key label 1 corresponds to two pieces of data to be stored of the data label a and the data label E; when the data to be stored corresponding to the key label 1 is decomposed for the first time, the data to be stored of the data label A with the prior distribution sequence of the corresponding data label is extracted and stripped. That is, when the data in the previous round is decomposed, the key tag 1 no longer corresponds to the data tag a, but the data to be stored of the data tag E corresponding to the key tag 1 is still reserved for subsequent decomposition and use. And thus, the decomposition processing of each piece of data to be stored is completed.
Through the processing steps, the data decomposition processing is efficiently completed, the disorder of the decomposed data is reduced, the processing speed of data rearrangement is facilitated, and the data decryption processing efficiency is improved.
It should be understood that although the steps in the flowcharts of fig. 6 and 8 of the drawings are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 6 and 8 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least some of the sub-steps or stages of other steps.
