Abstract

This application discloses an identity authentication method, a device, and a system. The method includes: obtaining a first master public key and a first private key from a key generation center; sending a ClientHello message; obtaining a second identity from a ServerKeyExchange message; generating a pre-shared key of a selected PSK mode by using the second identity, the first private key, and the first master public key; and completing identity authentication with a second device by using the pre-shared key. According to the method, device, and system provided in embodiments of this application, an identity can be transmitted by using information in the TLS protocol, without extending the TLS protocol. This can avoid a compatibility problem caused by TLS protocol extension.
