Abstract

The invention relates to an authentication method and device, a terminal and a computer readable storage medium, and relates to the technical field of mobile communication. The method comprises the steps that a first terminal receives an authentication request sent by a second terminal; the first terminal judges whether the first terminal and the second terminal are in the same authentication domain; under the condition of being in different authentication domains, the first terminal extracts an identifier of the second terminal in the authentication request and a public parameter of the authentication domain where the second terminal is located; the first terminal calculates a public key according to the identifier of the second terminal and the public parameter; and the first terminal authenticates the second terminal by using the public key. According to the technical scheme, the authentication efficiency can be improved, and the authentication cost is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to an authentication method, an authentication device, a terminal, and a computer-readable storage medium. Background technique [0002] Authenticating communication terminals is an important technology to improve network security. [0003] In related technologies, methods such as characteristic string authentication, certificate authentication, and algorithm authentication are mainly used. The authentication information of the terminal is stored on the authentication platform in this authentication domain, and two terminals in different authentication domains realize mutual authentication between cross-domain terminals through the authentication platform of their respective authentication domains and the third-party authentication center. Contents of the invention [0004] The inventors of the present disclosure have found the following problems in the ...
