Detailed Description
Referring to fig. 1, the off-line password encryption method for equipment leasing of the present invention has the same operation flow chart as the unlocking steps of the traditional off-line password encrypted leasing equipment under the normal condition of password synchronization between the leasing equipment and the service end, and also scans the information of the displayed equipment identification code, such as the equipment two-dimensional code representing the unique number of the equipment, on the leasing equipment through a smart phone or other intelligent terminals capable of connecting with the internet, reports the information of the equipment identification code to the service end, establishes communication connection with the service end, checks the tariff information, purchases the leasing time with corresponding use duration, obtains the unlocking password after confirming payment, can manually input the unlocking password to the leasing equipment after manually checking the unlocking password, the leasing equipment verifies that the unlocking password passes, the leasing equipment is unlocked, the equipment is successfully leased, and simultaneously starts to time counting and the lease time, the rental device automatically shuts down the service.
Because the leasing equipment and the service end are completely independent, no communication and information transmission is carried out between the leasing equipment and the service end, and meanwhile, a clock signal required by periodically resetting the codebook is not continuously provided for the dynamic password module by using a battery, the password asynchronism between the leasing equipment and the service end can be avoided, so that the leasing equipment cannot be normally unlocked; the off-line password encryption method for equipment leasing comprises an off-line password generation method and a password verification method.
The off-line password generation method comprises the following steps:
firstly, at least two groups of cipher sequences are generated, one group is a common cipher sequence, the other group is a super cipher sequence, one or one group of initialization ciphers is added according to the requirement, and each cipher in the two groups of cipher sequences is extracted from randomly generated passwords to be selected. The common cipher sequence is used for normal use; the super password sequence is used when the passwords of the leasing equipment and the server are not synchronous and the password of the common password sequence cannot be unlocked; the initial password is used by an administrator, or the super password sequence can not be unlocked for emergency use.
Referring to fig. 2, a specific method for obtaining a common password sequence, a super password sequence and an initialized password is that an optional password is randomly generated by permutation and combination according to the number and the number of digits of a password button on rental equipment; common simple passwords are filtered out, such as: 123456 or passwords all of the same number; screening out candidate passwords of ordinary, super and initialization passwords according to an offline password algorithm; then, randomly extracting a certain number of passwords from the screened candidate passwords of the ordinary, super and initialization passwords to be respectively used as the ordinary, super and initialization passwords, generating an ordinary password sequence, a super password sequence and an initialization password from the ordinary password, the super password and the initialization password according to the password types, burning the ordinary password sequence, the super password sequence and the initialization password into the leasing equipment in advance, storing the ordinary password sequence, the super password sequence and the initialization password into a server, displaying equipment identification code information on the leasing equipment, preferably selecting two-dimensional codes which are unique and corresponding to the identity of the leasing equipment, and associating the equipment identification code information with the corresponding ordinary password sequence and the super password sequence in the server according.
The password authentication method includes the steps as shown in fig. 3 and 4:
1) the user reports the identification code information of the display equipment on the rental equipment to the server through the intelligent terminal, and after payment is confirmed, the server firstly obtains a common password from the common password sequence according to the sequence and returns the common password to the intelligent terminal;
2) after the user inputs the obtained common password on the intelligent terminal into the leasing equipment, the leasing equipment extracts the corresponding pre-stored common password from the pre-stored common password sequence according to the sequence and compares the pre-stored common password with the input common password, the leasing equipment is unlocked when the comparison is consistent, and the unlocking state is kept in a preset time period; after each unlocking is successful, the password pointer of the common password sequence prestored in the leasing equipment is shifted down by one bit, namely the address +1 of the variable, and the password in the common password sequence prestored in the leasing equipment is recycled;
3) in a specific application process, for example, after a user pays a fee, a common password is obtained from a server, a password pointer of a common password sequence of the server is shifted down by one digit, and after the user obtains the common password, the common password is not input into rental equipment and does not use the rental equipment, the password pointer of the common password sequence of the rental equipment is not changed, and after the next user pays the fee, the common password obtained from the server is out of synchronization with the password of the rental equipment, so that normal unlocking cannot be realized, and aiming at the technical problem, the technical scheme provided by the invention is as follows: when a user feeds back an obtained common password to the server through the intelligent terminal and cannot unlock the rental equipment in a preset time period after obtaining the common password from the server, the server obtains a super password from the super password sequence according to the sequence and returns the super password to the intelligent terminal; for a user, the super password and the common password cannot be distinguished, and for rental equipment, the super password is not only an unlocking password, but also a password pointer resetting instruction of a common password sequence, namely an address of a variable is a 0 instruction;
4) after the user inputs the super password obtained on the intelligent terminal into the leasing equipment, the leasing equipment extracts the corresponding prestored super password from the prestored super password sequence according to the sequence and compares the prestored super password with the input super password, and the leasing equipment is unlocked when the comparison is consistent and is kept in an unlocking state in a preset time period; meanwhile, the leasing equipment resets the password pointer of the pre-stored common password sequence, and the server side also resets the password pointer of the corresponding pre-stored common password sequence, so that the synchronization of the server side and the password pointer of the leasing equipment is kept.
Under normal conditions, after a user scans codes and pays for payment, a server side extracts a common code from a common code sequence in sequence to the user, the user inputs the common code into rental equipment for unlocking, when the common code cannot be unlocked due to the fact that the code is not synchronized between the server side and the rental equipment, the common code is fed back to the server side, the server side provides a super code for unlocking the user, the super code adopts an encryption code method the same as the common code, and the problem that unlocking cannot be performed again exists. The intelligent terminal for managing the identity of the personnel or the intelligent terminal for the ordinary user with better credit rating provides an initialization password, and the initialization password can adopt a fixed password. After a server receives a manager reset request or receives super password unlocking failure feedback of a common user intelligent terminal with a better credit level, an initialization password is provided for a manager or a user, and after the manager or the user inputs the initialization password, password pointers of pre-stored common password sequences and super password sequences of the leasing equipment are reset; the server also resets the corresponding password pointers of the pre-stored common password sequence and the super password sequence, and keeps the synchronization of the password pointers of the server and the leasing equipment.
In order to improve the experience effect of a user and avoid the problem that unlocking cannot be performed frequently due to the fact that password pointers of a server and leasing equipment are not synchronous, the password verification method further comprises a synchronous correction unlocking step, when the common password input by the user is not consistent with the password pointer of the pre-stored common password sequence of the leasing equipment but is consistent with the password corresponding to the N bits behind the password pointer of the common password sequence, the leasing equipment is still unlocked, and meanwhile the password pointer of the common password sequence is corrected and updated. For example, the current password pointer points to the first address bit password in the common password sequence, the password input by the user is the second address bit password, the rental equipment can be normally unlocked, and only the password pointer of the common password sequence of the rental equipment is corrected and updated after unlocking, so that the rental equipment is kept synchronous with the server.
The password verification method also comprises a trial password verification step, after the correct trial password is input into the leasing equipment, the leasing equipment is unlocked after verification is passed, the leasing equipment keeps an unlocked state in a preset time period, meanwhile, the trial password is frozen and then verified by the leasing equipment, and the trial password is unfrozen and then verified by the leasing equipment after the next time of unlocking according to the input common password or super password. That is, the user is allowed to use for a certain period of time without payment within a specified time, or the user is allowed to use for a certain period of time for a corresponding number of times without payment before one successful unlocking, and the free use period is reset after the successful unlocking.
