Unique value generation and verification method and system

Abstract

The invention provides a unique value generation and verification method and system, and the method comprises the steps: obtaining a unique value request transmitted by a client, the unique value request being used for requesting a unique value; analyzing the unique value request to obtain identification information used for uniquely representing the client; obtaining local current system time anda count value, the count value being an accumulated count value after the local receives the access request each time; and calculating the identification information, the system time and the count value by using a preset algorithm to generate a unique value for verifying the identity of the client. The generated unique value is ensured to have higher security, so that the security and reliabilityof the unique value of the application are ensured, a basis is provided for subsequent security verification of the server on the access request, potential safety hazards caused by illegal access toinformation resources of the server are avoided, and the application range of the unique value in the field of information security is expanded.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for generating and verifying a unique value. Background technique [0002] The generation and verification of unique values ​​are more and more widely used in the field of computer information security. When the client sends an access request to the server, the server will generate a unique value and feed it back to the client. When the client will carry the unique value When the data packet is sent to the server, the server will check the legitimacy of the client by verifying the unique value, thereby ensuring the security of the client's access to information. In the prior art, the unique value generated by the server is often a random number, and the randomness cannot be guaranteed. This unique value may only be a random number generated by a random number generator, and this kind of random number often has a certain generation rule, which has ...

AI Technical Summary

Problems solved by technology

[0003] In view of this, the embodiment of the present invention provides a unique value generation and verification method and system to solve the problem in the prior art that the unique value generated by the server is relatively simple, has a low safety factor, and may easily cause security risks in access requests
