Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
Fig. 1 shows a flowchart of an embodiment of the adaptive weak password generation method of the present invention, which is executed by an electronic device, and it is understood that the electronic device may be a computer device, a mobile phone, a terminal, or the like. As shown in fig. 1, the method comprises the steps of:
step S110: and acquiring basic information, wherein the basic information comprises historical password information, user information and basic weak password information.
The historical password information comprises a password historically set by a user in a target service to be set with a weak password.
The user information comprises information such as user name, mobile phone number, identity card number and the like of the user. In an embodiment of the present invention, the user information further includes location information such as a registration address and a common address of the user.
The base weak cipher information may include weak cipher information that is now stored in a weak cipher library.
Step S120: acquiring the service type information of the target service, and determining a target weak password generation rule corresponding to the target service according to the service type information.
The target service of the embodiment of the present invention may be one or more service modules in the system, such as a login service module, an inquiry service module, a payment service module, an information modification service module, and the like. The adaptive weak password generation method can be applied to the password setting of a plurality of service modules in one system. Therefore, each service in the system corresponds to a password generation rule, and the target service corresponds to a target weak password generation rule.
The target weak password generation rule comprises a target weak password length rule, a target weak password strength rule and a target weak password calculation rule. The target weak password length rule sets the length of the password required to be set by the target service, and the embodiment of the invention does not specifically limit the target weak password length rule. For example, one embodiment may be no less than the target length. For example, for a login scene of a shopping website, the weak password length may be no less than 6 digits, letters or special symbols; for a payment scenario, the weak password may be no less than 8 digits, letters, or special symbols in length. The embodiment of the invention does not specifically limit the target weak password strength rule. For example, in one possible implementation, the target weak password strength rule may be "the password needs to be a combination of capital letters, lowercase letters and numbers", "the password needs to be a combination of any three of capital letters, lowercase letters, special characters and numbers", and so on. The target weak password calculation rule can be obtained by combining one or more information of historical password information, user information and basic weak password information in the basic information.
In a specific embodiment of the present invention, each service is correspondingly set with a security level, and corresponding generation rules can be correspondingly set for a plurality of services in a system according to the corresponding security levels. Specifically, the following steps may be included:
s1201: and acquiring the service type information of the target service. The service type information may be a service type identifier. For example, for a shopping website, service identification such as login browsing and payment can be divided.
S1202: determining a target security level corresponding to the target service according to the service type information; and determining a target weak password generation rule corresponding to the target security level.
By setting corresponding security levels for different services, the corresponding security levels for different services are different, and each security level corresponds to different weak cipher length rules, weak cipher strength rules and weak cipher calculation rules. And setting a lower security level for the target service with lower security requirement, for example, when a shopping website is browsed, the user can rapidly log in by adopting the lower security level. When shopping payment is carried out on the shopping website, a higher security level is required, and a user can carry out payment operation only by setting a higher-level password. Through the arrangement, one website or system can be adaptive to different service scenes, different service requirements are met, and therefore user experience is improved.
In a specific embodiment of the present invention, the corresponding password rule is further generated according to the registered address, the commonly used address and the current address information in the user information. Specifically, for a registered address which is a common address, such as a home address or an office address, a target weak password generation rule can be set only according to the target service; when the registered address is a temporary address, such as an address of an internet bar, the target weak password generation rule corresponding to the target service is adjusted, the generation rule of the target weak password is upgraded, the security strength of the target weak password is improved, a new target weak password generation rule is determined, and a plurality of weak passwords are generated according to the new target weak password generation rule, so that the security strength of the set password input by the user is improved.
Step S130: and generating a plurality of first weak passwords according to the basic information and the target weak password generation rule, wherein the target weak password generation rule is a combination rule of the historical password information, the user information and the basic weak password information.
And according to a target weak password generation rule, combining one or more information of the history password information, the user information and the basic weak password information in the basic information to obtain a plurality of first weak passwords.
In one embodiment of the present invention, one or more of the historical password information, the user information, and the basic weak password information may be a plurality of first weak passwords combined in a combination manner of AABB, ABAB, ABCD, and the like. Or a plurality of first weak passwords formed by combining the pinyin of the user name, the last four digits of the mobile phone number or the last four digits of the identity card and the like in combination modes of AABB, ABAB, ABCD and the like, wherein the pinyin of the user name, the last four digits of the mobile phone number or the last four digits of the identity card and the like are included in the user information. The specific combination mode can be set according to the target security level of the target service. For example, for the login service, the security level required is low, so the target weak password generation rule is simple, the target is generated, and the weak password in the corresponding weak password group is also the password with the low security level. For example, the weak password in the corresponding weak password group may be one of historical password information, user information, and basic weak password information. For the payment service, the required security level is higher, so the target weak password generation rule needs to perform complex combination besides the simple historical password information, the user information, the basic weak password information and the simple combination thereof, for example, the target weak password generation rule can be a plurality of first weak passwords formed by combining one or more information of the historical password information, the user information and the basic weak password information in a combination manner of AABB, ABAB, ABCD and the like.
In the embodiment of the present invention, according to the basic information, the generation of the plurality of first weak passwords according to the target weak password generation rule may be implemented by a target regular expression including a target weak password length rule, a target weak password strength rule, and a target weak password calculation rule.
The regular expression is a logic formula for operating character strings, which is a 'regular character string' formed by using predefined characters and the combination of the characters, and is used for expressing a filtering logic for the character strings, wherein the character strings comprise common characters and special characters. The regular grammar refers to the grammar of a regular expression, and the regular grammar refers to the operation logic of the character string. A regular expression is a text pattern that describes one or more strings of characters to be matched when searching for text.
Therefore, the program can be written and the regular expression can be written according to the target weak password generation rule. The specific implementation process is as follows: and acquiring a regular expression of the target weak password generation rule, wherein the regular expression is expressed by using Chinese keywords, and the Chinese keywords can be acquired from the description of the characters in the regular grammar. The target weak password generation rule can comprise simpler historical password information, user information, basic weak password information and simple combination thereof, and one or more of the historical password information, the user information and the basic weak password information are combined in combination modes such as AABB, ABAB, ABCD and the like. Therefore, the Chinese keywords in the target weak password generation rule can be obtained. The method comprises the steps of obtaining the description of the character form of the regular grammar corresponding to the Chinese key words of each target weak password generation rule in the regular expression, converting each Chinese key word in the regular expression into the character corresponding to the Chinese key word according to the description of the character form of the regular grammar corresponding to the obtained Chinese key word to generate the regular expression of the character form, and accordingly obtaining the target regular expression corresponding to the target weak password required by the computer. And performing associated storage on the target regular expression corresponding to the target weak password and the description information corresponding to the target regular expression. In the embodiment of the invention, the target regular expression is also packaged into a jar packet, so that a universal weak password generation calling tool is formed, a system administrator can adapt to weak password generation of corresponding services in the system by adaptively modifying information in jar, and the effect of adapting to various systems and service scenes is achieved.
In another embodiment of the present invention, the target weak password generation rule may be further implemented by a weak password calculation framework, and the weak password calculation framework is packaged into jar packets, so as to form a universal weak password generation invoking tool, and a system administrator may adapt to weak password generation of a corresponding service in a system by adaptively modifying information in jar, thereby achieving an effect of adapting to various systems and service scenarios. Specifically, the weak cryptographic computing architecture includes a presentation layer, a service layer, and a data layer.
The display layer provides weak cipher algorithm management and configuration management functions, and manages built-in target weak cipher generation rules (weak cipher algorithms) or target weak cipher generation rules (weak cipher algorithms) developed based on standard architecture and related configuration contents. The service layer can be a server and is used for providing a process management engine, performing off-line or real-time calculation and collecting calculation results, wherein data such as personal information data, personal password data, safety information data and risk information data of other data sources can be introduced for data calculation. The data layer provides a relational database for persistence, stores data such as configuration and the like, provides a non-relational database or a cache database for user data calculation, stores process data in various calculations, and ensures data safety and performance.
Step 140: and storing the first weak password and the service type information of the target service in a password library in a correlated manner in a weak password group corresponding to the target service, wherein historical password information, user information and basic weak password information are stored in the password group.
The weak password library is stored with historical password information, user information and basic weak password information, and also stores weak password groups associated with service type information, and different services correspond to different weak password groups. Therefore, after the plurality of first weak passwords are generated, the plurality of first weak passwords are updated to the weak password group corresponding to the target service. In addition to the plurality of weak passwords generated according to the target weak password generation rule, the weak password group of the embodiment of the invention also comprises a plurality of existing weak passwords with lower security than the first weak password passing through the target weak password generation rule. The existing weak password may be one or more of historical password information, user information, and basic weak password information, and a plurality of weak passwords generated by combining the existing weak password generation rules. It is to be understood that the existing weak password may be various weak passwords having a security lower than or equal to the first weak password.
The service type information and the associated weak password group can be stored in association with the user information. The information such as the user ID or the user name can be stored in association with the service type information and the weak password group, so that the weak password group of the user under the target service is determined.
In one embodiment of the invention, the updating of the password library is also performed regularly by setting the time period for updating the password library. The method comprises the following steps:
determining whether a time period for the cryptographic library update has been reached.
And when the time period for updating the password library is reached, detecting whether the historical password information, the user information and the basic weak password information have updating information.
And when the update information exists, acquiring the service type information of the target service, and determining a target generation algorithm corresponding to the target service according to the service type information.
And generating a plurality of second weak passwords according to the target generation algorithm according to the basic information and the updating information.
And storing the second weak password and the target service in association with each other into a weak password group corresponding to the target service in the password library.
By setting the time period for updating the password library, the system can actively discover the historical password information of the user, the user information and the updating information of the basic weak password information, so that the response is timely performed, and the security threat caused by untimely updating of the weak password after the information is updated is reduced. For example, when the mobile phone number of the user is changed, if the update is not detected in time, when the user sets the password, the changed mobile phone number will not be used as a weak password, so that the user may set the account password as the mobile phone number or a combination of the name and the last four digits of the mobile phone number, and the like, thereby the password set by the user is easy to crack, and potential safety hazards exist.
According to the embodiment of the invention, different weak passwords with different weak password generation rules are set according to different service types, so that one website or system can adapt to the security requirements of different service scenes, the security of password setting in the system is improved in a targeted manner, different service requirements are met, and the user experience is improved.
In addition, the updating information of the user is obtained by setting the updating period, and the weak password is further generated by using the updating information, so that the beneficial effects of actively finding and automatically updating the weak password library and responding to the security threat brought by the weak password in time are achieved.
Referring to fig. 2, a flow chart of a password detection method according to an embodiment of the invention is shown. The method is performed by an electronic device. As shown in fig. 2, the method comprises the steps of:
step 210: receiving setting information of a password to be detected input by a user, wherein the setting information comprises a target service corresponding to the password to be detected and the password to be detected.
When the user does not set the password and the system detects that the user uses the target service, or when the user modifies the password of the target service, the setting information input by the user is obtained.
The setting information comprises the password to be detected, the user information and the service type information of the corresponding target service. The service type information may be a service identifier, such as a service name. The user information may be user identification information such as a user ID, a user name, and the like.
Step 220: and determining a weak password group corresponding to the target service according to the service type information of the target service.
The weak password group corresponding to the target service of the user is stored in the password library, so that the weak password group corresponding to the target service of the user is obtained from the password library according to the user information and the target service, and the password to be detected input by the user is matched with the password in the weak password group.
Step 230: and detecting whether a weak password matched with the password to be detected exists in the weak password group, wherein the weak password group comprises historical password information, user information, basic weak password information and a first weak password, and the first weak password is generated according to the self-adaptive weak password generation method.
The step flow of the first weak password generation method is the same as that of the adaptive weak password generation method, and details are not repeated here.
Step 240: and when the weak password matched with the password to be detected exists in the password library, determining that the password to be detected is the weak password.
The weak passwords in the weak password group of the target service are traversed in the password library, and when the weak password matched with the password to be detected exists in the password library, the security of the password to be detected set by the user under the target service is relatively weak, so that the user needs to be reminded to modify the password. When the weak password matched with the password to be detected does not exist in the password library, the security of the password to be detected input by the user is in accordance with the security level requirement corresponding to the target service in the system, and the password can be set as the password of the user under the target service.

In addition, the updating information of the user is obtained by setting the updating period, and the weak password is further generated by using the updating information, so that the beneficial effects of actively finding and automatically updating the weak password library and responding to the security threat brought by the weak password in time are achieved.
