摘要
SSL VPN是基于SSL安全机制,在不改变现有防火墙构架的基础上,实现的一种安全网络构架。本文提出的PHI(Private Handshake Information)协议是专门为SSL VPN设计的控制协议,通过该协议可以增加SSL VPN的安全保护,建立更为可靠的透明安全隧道。本文详细地论述了PHI-SSL VPN的体系设计以及PHI协议的原理,并对可能的攻击进行探讨。
SSL VPN is a safety network framework implemented on the basis of SSL safety mechanism and the cur- rent firewall system. The PHI (Private Handahake Information) Protocol put forth in this paper is the control proto- col particularly designed for SSL VPN, by whih the safety protection of SSL VPN is strengthened and a more credi- bly transparent safety tunnel is built. This paper details the system design of PHI-SSL VPN and the principle of PHI. Moreover, it discusses the likelihood of the attack case.
