IP地址安全性研究及实验分析

讨论了IP地址存在的常见安全漏洞及其防范策略，分析了网络连接中各种地址的作用范围，并通过仿真实验和协议分析，从原理上探索了IP地址安全漏洞的根源所在，认为加强IP地址的安全性管理的关键在于发现网络上出现完全相同的两条连接，由于本地端口具有随机性、不确定性和瞬时性，易于实现两条不同的网络连接，因此，从现有技术角度来看，完全实现IP地址的安全管理具有相当的难度，指出了应该从本地端口作为突破口，来寻找强化IP地址安全管理的研究途径．

Study and experimental analysis on the security of IP address

The paper discusses the ways of IP address used illegally and the methods for preventing IP address used illegally, analyzes the action scope of all kinds of address in the network link, and researches the principle of IP address used illegally by experiment. To give a summary, the key of preventing IP address used illegally is to inspect the completely same double network link, but the local port of application layer is random, uncertainty and instantaneous number and to implement the completely same double network link is very easy, so there is extraordinary difficulty to prevent IP address used illegally from current technology, indicates the study measure for preventing IP address used illegally.
