Problems solved by technology

[0003] At present, digital signatures are often used to identify identities, but the storage and invalidation of private keys make this method flawed. Once the private key expires, all digital signatures related to it will no longer have "non-repudiation".
Then it is easy for the plug-in information to be copied, and the plug-in information replay attack

Abstract

The invention discloses a time type plug-in authentication method and system. The method comprises the following steps: step S100, a client initiates request information of applying for a plug-in to a server; step S200, the server releases applied plug-in information to the client according to device identification information of the client; step S300, the client applies to the server for time information authentication in the received plug-in information; and after the authentication success of the server, step S400 is executed; and step S400, the client updates the time information in the plug-in information to the current time when the plug-in information is authenticated. The purpose is to solve the problem that the plug-in information is subjected to tampering and replay attacks by authenticating the time in the plug-in information, and the security of the system is effectively improved.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to a method and system for time-based plug-in authentication. Background technique [0002] The rapid development of the Internet has brought about a series of Internet security problems. Hackers intercept the data packets sent by users and continuously send a valid data to the server fraudulently. Therefore, the server needs to determine which request is real and valid. [0003] At present, digital signatures are widely used to identify identities, but the storage and invalidation of private keys make this method flawed. Once the private key expires, all digital signatures related to it will no longer be "non-repudiable". Then it is easy for the plug-in information to be copied, and the plug-in information replay attack. [0004] Therefore, aiming at the defects of the above technical problems, the present invention provides related technical solutions for solving the problems....
