SYSTEM AND METHOD OF AUTHENTICATING TRANSMISSION IN NETWORK MEDIA

摘要

PROBLEM TO BE SOLVED: To provide a method of making safe transmission between two or more apparatuses. SOLUTION: The method makes safe the transmission between at least two apparatuses. A location limited physics token channel is connected to the first apparatus. A prior authentication information on the first equipment is saved at the tokens channel. The tokens channel is provided to the next apparatus which is the present apparatus between at least two apparatuses. The tokens channel is connected to the present apparatus. The prior authentication information on the present apparatus is saved at the tokens channel. The prior authentication information on the first apparatus is copied to the present information from the tokens channel. The above-mentioned provisioning, connecting, storing, and copying about each apparatus are repeated. The tokens channel is connected again at the first apparatus. The prior authentication information on each apparatus is copied to the first apparatus from the tokens channel. The method establishes secure communication between the first apparatus and each apparatus on the basis of the prior authentication information on the first apparatus and each apparatus that it is exchanged between the first apparatus and each apparatus using the tokens channel in each apparatus.
