SSL＼TSL中基于重新协商的中间人攻击及防范

随着因特网技术的不断发展,国际中对各种事务的处理也越来越依赖于全球化的因特网网络,如何确保网络通信安全,在很大程度上关系到事情的成败。因此,SSL＼TLS协议逐渐被应用于各种应用通话协议中,提供加密、验证等安全性服务。基于SSL＼TLS协议的漏洞,针对其的攻击方法逐渐出现,基于重新协商的中间人攻击方法就是一个很大的威胁。为了分析这种威胁到底有多大,本论文对中间人攻击方法的原理进行了探讨并简单介绍了一些攻击的实例。     

电子政务安全体系－－防联想研究院安全研究室主任韦卫

电子政务的安全可以分为信息安全和计算机网络安全两个方面。信息安全可以通过PRI、CA、安全认证协议、安全认证技术以及加密来实现;计算机网络安全却是通过物理隔离、防火墙、代理服务器、入侵监测等工具来实现。
