利用Winsock2 SPI和混沌一次一密的内网安全通信

Intranet Encryption Communication Uses Winsock2 Service Provider Interface

针对基于内网的不安全行为越来越多,传统的防火墙技术不能很好解决,本文提出了一种基于Winsock2 SPI网络封包截获技术和混沌的一次一密的内网加密通信模型,采用VC++6.0实现了通过访问控制来加强内网的通信安全。不改变已有通信系统的情况下实现了灵活的数据安全传输功能,对于加强内网的主机安全通信具有一定的通用性和应用价值。

This paper presents the model of the Intranet encryption communication based on the package interception technology of Winsock2 SPI and onetime pad of chaotic to solve more and more insecurity behavior which cannot be solved well by the traditional fire wall technology in intranet,and implements it with the VC＋＋ 6.0 combining the access control to strengthen the intranet communication security. The system can transfer data packets in security without changing the condition of the communication system. It is valuable to strengthen the intranet host computer communication security.
