摘要: 广播是普适计算环境中最基本的一种通信方式。对广播通信安全协议的研究显得十分重要。点对点的鉴别模式并不适用于广播安全;数字签名方法则对普适计算硬件要求太高。给出一种基于对称密钥算法的安全鉴别方案,通过对密钥发布方式的改进,满足普适计算硬件环境的广播安全鉴别,对μTESLA进行改进,避免了其由于时间同步错误导致的节点攻击。改进的方案获得更高的安全性能。

Abstract: Broadcast is the most basic one means of communication in ubiquitous computing computing environments.It is very important to research broadcast communication security protocol.Point-to-point identification model does not suitable for broadcast security;digital signature method is too high to hardware request of ubiquitous computing.In this paper,a safety program to identify is brought forward based on symmetric key algorithm,the key issue way’s improvement met the broadcasting hardware security identification in ubiquitous computing environment,and the μTESLA’s avoids the node attack because of time synchronization errors.The improved program obtains a higher safety performance.
