Customizable network identity authentication method based on SM2 algorithm

Abstract

A customizable network identity authentication method based on SM2 algorithm can realize the identity authentication by exchanging three data packets between an entity A and an entity B through communication and by processing the data packets. Based on TCP / IP (transmission control protocol / internet protocol), the data packets can be certificated by subjecting the contents of the data packets to encryption and signature by use of SM2 algorithm. The aim of customizable identity authentication can be realized by defining the value of a reserved word X in the data packets. The SM2 algorithm used in the invention has high encryption strength; and the method for realizing customizable identity authentication based on the reversed word can realize the identity authentication of a data communication party at the initial stage of a session, and can be used for agreement of encrypted data transmission symmetric keys, thereby eliminating the risk of identity fraud during network data transmission and protecting the security of the information system.

Description

technical field [0001] The invention relates to a self-definable network identity authentication method based on the SM2 algorithm. Background technique [0002] In recent years, network security issues have become increasingly prominent, and hacker intrusions and network attacks are increasing. With the continuous popularization of computer network technology, the public uses computers more and more. In particular, the construction of public information infrastructure has promoted government and enterprise Increasingly dependent on information systems, some businesses and systems related to the national economy and people’s livelihood have encountered unprecedented security challenges, such as the WikiLeaks website leaking a large amount of government confidential information; The attack resulted in the leakage of more than 6 million user data. These accidents fully illustrate the importance of network security to countries, governments and enterprises. [0003] The infor...

AI Technical Summary

Problems solved by technology

[0004] Network information security issues first need to solve the problem of information network identity authentication. Most of the existing network identity authentication methods use the RSA algorithm, which has low encryption strength, and there is a risk of identity forgery during network data transmission, which threatens the security of information systems.
