【摘要】 给出一种新的安全协议的设计方法——组合设计方法,首先分别实现各个安全目标,然后将它们组合为一个新的安全协议。组合方法设计安全协议具有易于实现、易于验证等优点。给出组合规则,使用组合方法实现了普适计算环境下认证协议及密钥协商协议的设计。更多还原

【Abstract】 This paper proposed a novel design method-design by composition,constructing a complicated protocol from simple protocol primitived without destroying the security properties established by each independent part.This method made the design and verification of the protocol easier to handle.The regulations of composition had been present.And with these regulations of composition design,this paper implemented an authentication protocol and a key agreement protocol for ubiquitous computing network.更多还原
