To easily construct a secure data channel between terminals by performing signalling safely.
A session management apparatus equipped with a means for performing connection to a first apparatus and a second apparatus via networks has a means for performing mutual authentication between itself and the first apparatus, establishing a first encrypted communication channel between the session management apparatus and the first apparatus, and holding a name of the first apparatus making it to correspond to identification information for the first encrypted communication channel; a means for establishing a second encrypted communication channel based on mutual authentication between the session management apparatus and the second apparatus; a means for receiving a message comprising the name of the first apparatus via the first encrypted communication channel from the first apparatus, and judging whether or not the name of the first apparatus comprised in the message is correct, by comparing the name of the first apparatus comprised in the message with the name of the first apparatus held being made to correspond to the identification information for the first encrypted communication channel; and a means for sending that message to the second apparatus via the second encrypted communication channel.
