Data confidentiality service on top of transmission control protocol/internet protocol

A scheme for providing data confidentiality service on top of transmission control protocol/internet protocol (TCP/IP) is proposed for connection-oriented message transmission. A novel security service architecture consisting of interactive application program, client/server, and security service modules is presented to provide the data confidentiality service. Also, the functional mechanism of the proposed scheme is given. W. Diffie and M. Hellman's (1976) key distribution method is used for session key generation and distribution.<
