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. 本公开涉及一种认证方法、装置、终端和计算机可读存储介质，涉及移动通信技术领域。该方法包括：
