Abstract

The invention provides a bidirectional authentication method and a communication system. The bidirectional authentication method comprises the following steps: a client sending a first request messageto a server; wherein the first request message is used for requesting a certificate and a password suite of the server; the server sending a first response message to the client; wherein the first response message comprises a certificate, a password suite and a first random number of the server; the client verifying the certificate of the server, selecting a target encryption algorithm in the password suite after the certificate passes the verification, and sending the target encryption algorithm and a second random number to the server; the server signing the target encryption algorithm andthe second random number, and sending signed signature data to the client; the client performing signature verification on the signature data to complete bidirectional authentication; wherein the first random number and the second random number are used for generating a key. The communication efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a two-way authentication method and a communication system. Background technique [0002] With the development of communication technology, more and more attention has been paid to the security issues when the client and the server communicate. Before the client communicates with the server, the client authenticates the server or the server authenticates the client to ensure communication security. important means. [0003] When the client and server communicate using the basic Hyper Text Transfer Protocol over Secure Socket Layer (https for short) communication protocol, the https two-way authentication is usually used to ensure data communication security. In the existing https two-way authentication process, the number of interactions between the client and the server is large, the communication process is complicated, and the communication time is too long. In some app...
