Abstract
A device authentication method, a service access control method, a device, and a non-transitory computer-readable recording medium are provided. In the device authentication method, an authentication request device issues an authentication request transaction in a distributed ledger, and an authentication response device reads the authentication request transaction in the distributed ledger and performs authentication. Thus, no third-party authentication center or coordinate device is required to participate in an authentication handshake process, thereby reducing deployment overhead of an authentication system and improving efficiency of authentication and access service control.
