摘要
构造一个具有自恢复能力和抵御合谋攻击能力的组群密钥发布协议,该协议特别适合于高度易失传输环境,例如无线传感器网络.基本方法是在时域上应用拉格朗日插值技术实现秘密分割—重构方案.本文精确叙述了该类协议应满足的安全性质,证明了该构造满足所要求的安全性质,分析了它对计算、存储及带宽资源的要求,并给出分别针对带宽和存储量的两种优化改进方案.论文还讨论了协议的参数选择问题.
A group-key distribution protocol is designed which has the capability of self-recovery and coalitionattack-resisting, particularly suitable for highly lossy transmission environment such as wireless sensor networks. The basic method applies Langrange interpolation techniques in time-domain to implement a secrecy fragmentation-recon- struction scheme. This paper precisely specifies the desired security properties, proves the constructed scheme to satisfy all desired properties, analyzes the requirements on computation, storage and bandwidth resources, and proposes two improvements with respect to bandwidth apd storage optimization. This paper also discusses the parameter selection problem.
