摘要
本文以计算机网络开放系统互连(OSI)参考模型中的传输层(TP-4)标准服务为基础,在其提供的服务中,增添相应的保密机制及修改某些部分,来向上层(会话层)提供包括保密通信功能的有效的传输服务(TP-S)。文中着重讨论了防止信息丢失攻击、防止流量分析攻击、信息流篡改攻击检测、拒绝信息服务攻击检测以及伪连接初始化攻击检测等保密目标,所采取的加密方法和工作方式以及为达到上述目标提供的有效服务。
This Paper is based on transport protocol in Open System Interconnection of Computer Network.By appending an appropriate security mechanisms and alterring some contents into transport standard service an available transport service including encipherment function provided to upper layer(Session layer)is presented.In this paper it mainly discribes an encipherment algorithm;working mode and provides an available service for avoiding information loss attack and traffic analgsis attack,detection of the distortion of information flow and the initialization of the false connection attack.
