Description
Technical Field
The invention relates to an encryption and decryption method, in particular to a statement filtering authentication method and an authentication system.
Background
At present, with the deep development of the internet +, software systems have been deep into different scenes of various industries, and the connection between different systems is becoming tighter and tighter. Therefore, with the advent of various cloud platforms, combination systems, single sign-on services, and the like, communication between systems on the same platform and between systems is becoming more frequent, and thus, the requirements for security and reliability of communication are becoming higher. The services are that the original single software system is split into different functional components, and the different functional components are communicated with each other through contract dependency relationship among the services to form a complete system application, and the services under the unified platform can be communicated with each other and can also be communicated with non-trusted services outside the platform, such as a browser software end, an android system software end, an apple system software end, a client system software end and the like. However, in any communication mode, it is necessary to ensure the security and reliability of the request before the execution of the communication request is acquired.
At present, for the requirement of cross-platform unified authentication in the prior art, a single sign-on solution is generally used, and an authentication system needs an authentication server which is a browser application deployed independently; the server side is mainly responsible for authentication work of the user, interacts with the database and jumps to a corresponding request picture in a redirection mode after authentication is finished. The authentication client and the system client are deployed together, and authentication protection is carried out on protected resources in a filtering mode. For each request for accessing protected resources, the client analyzes whether the request parameters contain user credentials, and if not, client authentication or server authentication is carried out; in practical application scenarios, single sign-on needs to be combined with an authority control framework, such as apache shiro (JAVA security framework). The security framework uses the user session to cache the user authentication information, which also indicates that the client needs to store the user state cache. The client security framework uses the cache information to perform request authentication, and simultaneously provides a group of declaration interfaces, so that the interfaces can be subjected to authority verification description, the interceptors perform authority verification, and interface access is performed after the interfaces pass.
In summary, for the requirement of cross-platform unified authentication, an independently deployed authentication server is required, and thus, for a cross-region distributed deployment scheme, there are disadvantages that the deployment mode of the authentication server is fixed, the network constraint is strong, and the load balancing or distributed scheme is complex. The non-trust request means that the requesting client and the receiving server are not on the same cloud platform, and the client validity cannot be inquired in the registry. In many practical scenes, many cross-platform applications such as a WeChat end, a mobile phone end, a browser end and the like cannot be deployed in a unified cloud platform. Therefore, the non-trusted request needs to perform user authority authentication, such as user basic information, user role, user resource authority, and the like. And the client combines the authority control frame, needs to store the user state, caches the user authority information, and does not support stateless conversation. The client interfaces communicate with each other without corresponding security authentication strategies, and only user information can be mutually transmitted and the user authentication strategies are adopted for correspondence. The problem derived from this is that the existing non-trusted authentication system has low security of encryption algorithm, is easy to copy, and is not beneficial to the non-trusted client and the client server, so it is necessary to develop an encryption and decryption method to solve the above problem.
