Document Type and Number:
WIPO Patent Application WO/2021/064978
Kind Code:
A1
Abstract:
This terminal, which performs authentication by TLS 1.3 with a server connected through a communication network, is characterized by comprising: a transmission means for transmitting, to the server, a ClientHello message which includes a first identifier and a first short-term public key necessary for generation of a shared key for encrypting a message during a handshake of the TLS 1.3 by key exchange with mutual authentication using ID based cryptography; a reception means for receiving, from the server, a ServerHello message which includes a second identifier and a second short-term public key necessary for generation of the shared key; and a generation means for generating the shared key using the first identifier, the first short-term public key, the second identifier, and the second short-term public key.
