Security authentication method, equipment and system based on transport layer security protocol

Abstract

The embodiment of the invention discloses a security authentication method, related equipment and a communication system based on transport layer security (TLS). The security authentication method based on a TLS protocol includes the steps that a client sends client initialization handshake information to a server, the client initialization handshake information carries N algorithm set identifications, and an algorithm set corresponding to each one of M algorithm set identifications of the N algorithm set identifications comprises an SM2 algorithm; server initialization handshake information sent by the server is received, and the server initialization handshake information carries a first algorithm set identification which is one of the M algorithm set identifications; security authentication is carried out on the basis of a first algorithm set corresponding to the first algorithm set identification and the server. A mechanism for data transmission through the SM2 algorithm is provided, so that advantages of the SM2 algorithm in the security factor are brought into full play, and safety and performance of security authentication and data transmission are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a security authentication method, device and system based on a security transport layer protocol. Background technique [0002] Currently, the Transport Layer Security (TLS) protocol is the most widely used security protocol in network transmission. The TLS protocol is an international standard, and the TLS protocol uses a large number of internationally used related algorithms. [0003] The SM2 algorithm is an asymmetric encryption algorithm issued by the National Standard Cryptography Bureau of China, and is designated by the Ministry of Industry and Information Technology to replace the RSA algorithm. Among them, the SM2 algorithm adopts the principle of elliptic curve, its key is relatively shorter, its security is relatively higher, and its performance is relatively higher. Among them, the SM2 algorithm includes: SM2 public key encryption algorithm, SM2 signature al...
