中文摘要：

首先介绍了TCP／IP协议中的漏洞及常用的IP欺骗的攻击手段，并针对以上问题引入生物多样性的思想，使得对话双方在通信中进行计算机认证，用多样性函数方法代替可预知序列号，建立安全的通信信道。

英文摘要：

This paper first discusses the limitations of the TCP/IP protocol suite and the usual attacking ways based on IP cheating. Later, the paper introduces the theory of diversity in biological systems to this field. In this model, both sides take computer authentication and use variety of functions instead of predictable sequence numbers while exchanging data, establish a safer channel.
