Extensible multi-identity authentication system and method in power system

Abstract

The invention discloses an extensible multi-identity authentication system and method in a power system, and the system comprises an upper-layer application module, a multi-identity authentication module and a real-time library. The multiple identity authentication module is divided into an identity authentication layer and a third-party identity authentication plug-in layer, and the identity authentication layer is directly called by the upper-layer application module and is responsible for reading a third-party identity authentication type set in the real-time library to dynamically load the specific third-party identity authentication plug-in layer; and the third-party identity authentication plug-in layer is responsible for calling a native interface provided by a third-party identity authentication manufacturer and shielding the problem that interfaces provided by different manufacturers in the same third-party identity authentication mode are not uniform. According to the invention, through the layering idea of multiple identity authentication modes, the expandability of the multiple identity authentication module on the third-party identity authentication mode and the online switching function of the third-party identity authentication mode are realized.

Description

technical field [0001] The invention relates to an expandable multiple identity authentication system and method in a power system, belonging to the technical field of multiple identity authentication. Background technique [0002] In the existing technical solutions, most power systems can only support a multi-identity authentication method of two-factor authentication, such as: the most common two-factor authentication of user passwords and digital certificates; There are two authentication mechanisms: [0003] First: Support to remove the authentication of the digital certificate, and only verify the user name and user password; [0004] Second: Support two-factor authentication of user name, user password and digital certificate; [0005] However, it does not support online expansion of a new third-party authentication method, nor does it support online switching to another third-party authentication method for the following reasons: [0006] The current multi-identit...

Problems solved by technology

Considering that with the continuous development of security technology, there will be more and more third-party identification methods. The old identification methods may become unsafe in the future, and it is necessary to switch to a more secure identification method. At the same time, in order to For higher security, it may be necessary to periodically switch the third-party authentication method back and forth among several third-party authentication methods. However, the current multi-identity authentication module and the underlying third-party authentication method are tightly coupled access, resulting in only partial Meet or fail to meet the above requirements and the cost of transformation and maintenance is high, so a better multi-identity authentication method is needed to solve the above problems
