【摘要】 随着Internet的迅速发展,以前在企业内部网络中开通的业务也纷纷移植到Internet上。Internet构建在TCP/IP协议上,而TCP/IP协议并未提供任何安全措施,针对Internet存在的安全问题,人们提出了多种解决方案,其中SSL协议便是Internet上应用最为广泛的安全协议。SSL协议隶属于会话层,处于有连接的会话层(TCP)之上,它一经产生就在Internet领域发挥了它的巨大作用。 目前已经有若干国外厂商推出了基于SSL的安全产品,但是大多采用一些低安全强度的算法,难以满足我国信息安全的需要。针对电子政务、电子商务和军队信息化建设的安全需要,本文作者在研究SSL协议的基础上,并参考当前较为成功的SSL实现的技术方案,开发了能够充分保证Web通信安全的高强度SSL安全代理(以下称SSL安全代理)。 本文结合SSL协议分别从保密性、数据完整性和身份认证三个方面分析了其安全性,针对目前存在的对SSL的攻击提出了相关的应对措施,并详细描述了SSL安全代理的设计思想与实现方法。

【Abstract】 With the quick development of the Internet , various services runing in enterprise internal networks have been ported to the Internet. The Internet is based on TCP/IP protocols, but TCP/IP protocols can’t guarantee the security. To solve these problems , various solutions have been broutht up. SSL protocol is one of the most famous secure protocols . It belongs to the session layer , and plays an important role in the Internet.Many develops have released secure products based on SSL , but most of them adopt weak cryptography algorithms and can’t satisfy the indeeds of information security in our country. To satisfy the demands of the e-governmental affair ,e-commerce and the army’ s information construction, we developed a SSL security proxy based on high-strength SSL.The article firstly analyses the security of SSL based on Confidentiality , integrity and Authentication , then provides some measures against current attacks on SSL protocol, and finally, describes the design and implementation of the SSL security proxy.
