Abstract

An authentication system receives encrypted terminal identification information and terminal identification information, from a transmission terminal, and determines whether decrypted identification information decrypted using a terminal public key obtained by the authentication system matches the terminal identification information received from the transmission terminal.

Description

technical field [0001] The present invention relates to an authentication system, a transmission terminal, and a transmission system, and in particular to an authentication system for performing terminal authentication on a transmission terminal, where at least one signal of image data and sound data is received or received between the transmission terminal and another transmission terminal. send. Background technique [0002] In recent years, with the continuous emergence of requirements to reduce business travel expenses and travel time, transmission systems such as video conferences using communication networks such as the Internet have been popularized. This transmission system implements a videoconference by transmitting or receiving image data and audio data between a plurality of transmission terminals. Moreover, the current broadband environment has been further enriched, and it is possible to receive and transmit high-quality image data and high-quality voice data,...
