Abstract

A communication system in which first and second communication apparatuses (4a,4b) equipped with arrangement means for arranging encryption and decryption logic used for a communication system which carries out a communication by encrypting a protocol positioned in a transport layer and a third communication apparatus (4c) not equipped with arrangement means for arranging said encryption and decryption logic are connected to a network respectively, wherein said first and second communication apparatuses are equipped with protocol encryption means for encrypting and transmitting at least a payload of said protocol in a packet of an information unit to be transmitted and received according to an encryption logic arranged by said arrangement means and both of encryption protocol processing means consisting of protocol decryption means for decrypting said encrypted protocol payload to be received according to a decryption logic arranged by said arrangement means and ordinary protocol processing means without being accompanied by said encryption and decryption logic, said third communication apparatus is equipped with only an ordinary protocol processing means without arrangement means for arranging said encryption and decryption logic, when said first communication apparatus communicates with said second communication apparatus, said encryption protocol means is selected by the arrangement means of said encryption and decryption logic so as to communicate by said encryption protocol means and at the same time, and when said first communication apparatus communicates with said third communication apparatus, said ordinary protocol processing means without being accompanied by said encryption and decryption is selected by the arrangement means of said encryption and decryption logic so as to carry out a communicate with said third communication apparatus by said ordinary protocol processing means.
