The invention provides an authentication method and apparatus, a computer readable storage medium and an authentication system. The method comprises the following steps: receiving a call request sent by a client, wherein the call request is used for calling services from a server; authenticating the client to determine whether the client has the authority of calling the service; and after authentication success of the client, forwarding the call request to the server, so that the server makes response to the call request and calls the service. According to the authentication method and apparatus provided by the invention, the client calling the service is authenticated by a security platform, thereby ensuring that only the client having the authority of calling the service can call the service, and thus the security is improved; and meanwhile, the authentication operation is executed by the security platform, which is conductive to performing unified management on the authority of the client and improving the management efficiency.
