An Improved Security TCP Handshake Protocol with Authentication

TCP three-way handshake protocol has a variety of security risks for the absence of safety certification, not enabling to make immense modification in it if maintained compatibility with the protocol. In this paper, we present an improvement by using the alternative items of TCP packets, on this basis of which a security protocol is designed with authentication. The new protocol is compatible with the original protocol, adding authentication against various attacks. The formal analysis proves that the security protocol is in accordance with established safety goals.
