Background

In the prior art, when a user logs in a service system through a login device, an independent authentication center is generally needed to verify a user account and a password, only the authentication center can receive information such as the user account and the password, and other service systems only receive indirect authorization of the authentication center without providing a login entry. The indirect authorization is realized through an authorization token, the authentication center sends the authorization token to the service system after successfully verifying the user account and the password, and the service system takes the authorization token and then creates a session with the login equipment, so that the login equipment successfully logs in the pre-logged service system.

Specifically, fig. 1 is a schematic diagram of an interaction process of a login device, a service system, and an authentication center provided in the prior art, where as shown in fig. 1, the login device sends an access request to a service system a through a browser, after the service system a receives the access request, verification fails because a user account is not logged in, and the service system a jumps a current page to an authentication page of the authentication center and uses an address of the service system a as a parameter. The authentication center determines that the user account is not logged in, and therefore returns information for failing to verify and reminding the user to log in the account.

The login equipment sends a login request for logging in the service system A to the authentication center, wherein the login request carries a user account, a password and an address of the pre-logged service system A. And after the authentication center successfully verifies the user account and the password, creating a session and an authorization token, and sending the authorization token to the service system A according to the address of the service system A. And after receiving the authorization token, the service system A sends the authorization token and the address of the service system A to the authentication center in order to verify the validity of the authorization token. And after receiving the authorization token and the address of the service system A, the authentication center determines that the authorization token is valid based on the address of the service system A, registers by adopting the received address of the service system A, and returns the information that the authorization token is valid to the service system A. And after determining that the authorization token is valid, the service system A creates a session between the service system A and the login equipment, so that the login equipment logs in the service system A and accesses protected resources.

When a single authentication center is responsible for the verification of a large service system group, the authentication center needs to make an access application to the authentication center because the project of the large service system group comprises dozens of service systems and the login equipment needs to make a login access to the service systems in the service system group, so that the request is slow or even blocked because the access amount of the authentication center is too large.

According to the target device identification information in the obtained login request and the corresponding relation between the device identification information and the login information which is stored in advance, the target login information corresponding to the target device identification information is determined in the corresponding relation, so that the system identification information and the login time of the business system which is logged in by the login device are determined from the target login information, the number of the logged business systems is determined, and the number is represented by a letter n.

In order to reduce access requests to the authentication center, in the embodiment of the present invention, after it is determined that the login device performs continuous access to the service systems in the service system group and it is determined that the number of the logged-in service systems of the login device reaches a certain number, the remaining unregistered service systems in the service system group may be directly logged in without passing authentication of the authentication center.

In order to determine whether the login device performs continuous access, in the embodiment of the present invention, a preset time threshold is preset, where the preset time threshold is set based on experience, and if it is desired to improve the security of the login service system, the preset time threshold may be set to be smaller, and if it is desired to improve the robustness of the login service system, the preset time threshold may be set to be larger.

And according to the login time of the last logged-in service system and the current time of the pre-logged-in service system, determining the difference value between the current time and the login time of the last logged-in service system.

According to the difference and the preset time threshold, if the difference is smaller than the preset time threshold, the login request can be determined to be continuous access to the service systems in the service system group, and if the difference is not smaller than the preset time threshold, the login request can be determined not to be continuous access to the service systems in the service system group.

Example 2:

in order to improve the security of system login, on the basis of the foregoing embodiment, in an embodiment of the present invention, before determining that the login device successfully logs in the service system identified by the target system identification information, the method further includes:

determining M coordinates on a curve corresponding to the curve function of the N-1 times according to a pre-generated curve function of the N-1 times, and randomly distributing the M coordinates to M service systems, wherein N is smaller than M, and a constant item coefficient of the curve function of the N-1 times is login state identification information;

determining target login state identification information in the curve function for the N-1 times according to N-1 coordinates corresponding to any N-1 logged-in service systems and coordinates corresponding to a pre-logged-in service system identified by the target system identification information;

and if the target login state identification information is the same as the login state identification information, executing the subsequent step of determining that the login equipment successfully logs in the service system identified by the target system identification information.

In the embodiment of the invention, in order to log in the service system, the login state identification information is generated in advance, and the login into the service system is determined based on the login state identification information. In order to prevent the security of the login service system from being reduced due to the fact that the login state identification information is leaked, in the embodiment of the invention, the login state identification information is preset to be a constant, and an N-1-time curve function is generated in advance based on the login state identification information, so that the login state identification information is hidden in the N-1-time curve function, and the risk of the login state identification information leakage is reduced.

Specifically, in a pre-generated N-1-time curve function, preset login state identification information is used as a constant term coefficient of the N-1-time curve function, wherein N is a preset number threshold, and the login state identification information is hidden in the N-1-time curve function, so that the safety of the login state identification information is improved.

For example, the N-1 th-order curve function is f (x) ═ L + a₁x+A₂x²+……+A_N-1x^N-1The constant term L in the N-1-th-order curve function is preset registration state identification information, and if N is 2, a first-order curve function is generated in advance, and if N is 3, a second-order curve function is generated in advance, and y is ax²+ bx + c, the constant term coefficient c of the quadratic curve function is the login state identification information hidden in the quadratic curve function.

The number of the service systems contained in the service system group is M, M coordinates are determined according to the curve function of the N-1 times, the M coordinates are randomly distributed to the M service systems, each coordinate can be represented by (M, f (M)), and the M coordinates are all located on the curve corresponding to the curve function of the N-1 times. The total number of the service systems included in the service system group is M, and the preset number threshold N does not reach the total number M of the service systems, so N is certainly smaller than M.

For example, the service system group includes 5 service systems, and the preset number threshold N is 3, that is, after logging in 3 of the service systems, the remaining 2 service systems in the service system group may be directly logged in. According to the function of a quadratic curve y ═ ax²And determining 5 coordinates by + bx + c, randomly allocating the 5 coordinates to 5 service systems, wherein the coordinates corresponding to the 5 service systems are the coordinates of 5 points on the curve corresponding to the quadratic curve function.

And when the number N of the logged-in service systems is greater than a preset number threshold value N, randomly selecting any N-1 service systems from the N logged-in service systems, determining N-1 coordinates corresponding to the N-1 service systems, and determining the coordinates corresponding to the pre-logged-in service system identified by the target system identification information.

And determining a curve function for N-1 times according to the N-1 coordinates corresponding to the N-1 service systems and the coordinates corresponding to the pre-login service system, and determining the identification information of the target login state according to the curve function for N-1 times. According to the determined target login state identification information and the pre-stored login state identification information, if the target login state identification information is the same as the login state identification information, the login request is a login request generated and sent by the login device and is not modified in the sending process, and therefore the subsequent step of determining that the login device successfully logs in the service system identified by the target system identification information is executed.

If the target login state identification information is different from the login state identification information, the login request is not the login request generated and sent by the login equipment, and is modified in the sending process, and the fact that the login equipment does not successfully log in the service system identified by the target system identification information is determined.

Example 3:

determining target login information corresponding to the target equipment identification information according to the target equipment identification information and a corresponding relation between pre-stored equipment identification information and login information;

and if the target system identification information does not exist in the target login information, determining the system identification information and the login time of the n service systems which are logged in by the login equipment from the target login information.

In order to improve the login efficiency of the pre-login service system, in the embodiment of the invention, before determining the system identification information and the login time of the n service systems which are logged in by the login equipment, the electronic equipment also determines in advance whether the login equipment has logged in the pre-login service system identified by the target system identification information.

And determining the identification information of the target equipment in the corresponding relation according to the identification information of the target equipment and the corresponding relation between the pre-stored equipment identification information and the login information, and determining the target login information corresponding to the identification information of the target equipment.

Judging whether target system identification information exists in the target login information according to the target login information corresponding to the target equipment identification information, if the target system identification information does not exist in the target login information, indicating that the login equipment does not log in the pre-login service system identified by the target system identification information, and determining the system identification information and the login time of the n service systems logged in by the login equipment from the target login information.

If the target login information includes target system identification information, in the embodiment of the present invention, the method further includes:

and if the target system identification information exists in the target login information, determining that the login equipment has logged in the service system identified by the target system identification information.

If the target login information contains the target system identification information, the login equipment is indicated to already log in the pre-login service system identified by the target system identification information, so that the pre-login service system does not need to be logged in again, and the pre-login service system can be directly used.

Example 4:

in order to realize the login of the pre-login service system, on the basis of the foregoing embodiments, in an embodiment of the present invention, the method further includes:

if the difference is not smaller than the preset time threshold or if the number N does not reach the preset number threshold N, sending a login request to an authentication center according to a user account and a password carried by the login request;

and receiving an authorization token sent by the authentication center, and determining that the login equipment successfully logs in the service system identified by the target system identification information.

If the difference is not less than the preset time threshold or the number n of the logged-in service systems does not reach the preset number threshold, it indicates that the logging-in device cannot directly log in the pre-logged-in service system. Therefore, in order to realize the login of the pre-login service system, in the embodiment of the present invention, the electronic device further sends a login request to the authentication center according to the user account and the password carried in the login request. The process of the authentication center performing authentication based on the user account and the password belongs to the prior art, and is not described in detail in the embodiment of the present invention.

Specifically, the service system in which the login device logs in the identification information of the target system based on the authorization token belongs to the prior art, and details thereof are not described in the embodiment of the present invention.

As a possible implementation manner, in the embodiment of the present invention, after determining that the login device successfully logs in the service system identified by the target system identification information, the target system identification information and the current time of the pre-login service system in the login request are also recorded in the target login information.
