A terminal for performing authentication through TLS 1.3 with a server connected via a communication network. The terminal includes a memory and a processor configured to execute transmitting, to the server, a ClientHello message including a first identifier and a first short-term public key, which are needed to generate a shared key for encrypting a message during a handshake in the TLS 1.3, through key exchange with mutual authentication using ID-based encryption; receiving, from the server, a ServerHello message including a second identifier and a second short-term public key, which are needed to generate the shared key; and generating the shared key using the first identifier, the first short-term public key, the second identifier, and the second short-term public key.
