  Distributed network of the computer and the design defects of the TCP
protocol are given to the network attack to be multiplicative. Based on the
simple and open assumptions of the TCP protocol in academic and collaborative
communication environments, the protocol lacks secure authentication. In this
paper, by adding RSA-based cryptography technology, RSA-based signature
technology, DH key exchange algorithm, and HAMC-SHA1 integrity verification
technology to the TCP protocol, and propose a security strategy which can
effectively defend against TCP session hijacking.
