Provided is a high-speed and light-weighted authentication system that makes IP address filtering possible and does not impair real-time property even on a network including many and unspecific entities (communication devices). In a communication system that a plurality of communication devices are coupled together such that mutual communication is possible over the network, the communication devices communicate with a server under a secure environment, when authentication has been obtained from the server, random seeds of the same value and individual identifiers are issued to them, each communication device generates the IP address that includes a pseudorandom number and the identifier, and the communication devices establish communication between the communication devices that include the pseudorandom numbers that are mutually the same in their IP addresses.
