Abstract

The invention relates to a mutual authentication method between a terminal and a server. The method comprises that: the terminal generates an identity number and a first random number and sends the identity number and the first random number to the server; the server verifies whether the identity number exists in a database of the server; the server generates a first operation result according to the identity number, the first random number and a server secret key, and the first operation result and a second random number are transmitted to the terminal; the terminal generates a second operation result according to the identity number, the first random number and the server secret key and carries out authentication on the server according to the first and second operation results; the terminal generates a third operation result according to the second random number and a terminal secret key and sends the third operation result to the server; and the server generates a fourth operation result according to the second random number and the terminal secret key and carries out authentication on the terminal according to the third and fourth operation results.

Description

technical field [0001] The invention relates to a two-way authentication method between a terminal and a server. Background technique [0002] With the development of communication technology, there are more and more types of communication terminal products and their applications are becoming more and more extensive, but communication networks are also being attacked more and more. Therefore, most of the existing communication networks are The terminal uses a fixed user name and password for authentication to increase security. However, due to the long-term use of a fixed user name and password, the user name and password are easy to be stolen. Therefore, the security of the communication method using a fixed user name and password is low. Contents of the invention [0003] In order to solve the problem of low communication security between the terminal and the server in the prior art, it is necessary to provide a two-way authentication method between the terminal and the...
