摘要: 设计安全合理的密钥管理方法是解决无线传感器网络安全性问题的核心内容。基于Exclusion Basis System (EBS)的动态密钥管理方法由于安全性高，动态性能好，节约存储资源，受到了广泛关注。但同时存在共谋问题，即对于被捕获节点通过共享各自信息实施的联合攻击抵抗性较差。针对这一问题，该文利用一种特殊形式的三元多项式(同化三元多项式)密钥取代EBS系统中的普通密钥，并在分簇式的网络拓扑结构基础上，设计了一种基于EBS的无线传感器网络动态密钥管理方法。仿真与分析结果表明，相比于采用普通密钥或是二元多项式密钥的方法，该文方法不仅可以有效地解决共谋问题，提高网络对被捕获节点的抵抗性，而且显著减低了更新密钥过程中的能量消耗。Abstract: Security of wireless sensor networks has attracted much attention in recent years and key management is a critical issue of it. EBS-based dynamic key management scheme is a new approach for wireless sensor networks. The major advantages of EBS-based dynamic key management scheme are enhanced network survivability, high dynamic performance and better support for network expansion. But it suffers from the collusion problem, which means it is prone to the coordinated attack of the compromised nodes. In this paper, a special kind of polynomial, the common trivariate polynomial, is presented, which can guarantee that all the nodes having the same polynomial can get the same key. The common trivariate polynomial keys are used in stead of the normal keys in EBS system and a new dynamic key management scheme is designed for clustered wireless sensor networks. Analytical and simulation results show that compared with the former works, the proposed scheme can greatly improve the network resilience to the attack of the compromised nodes and decrease the energy consumption in the process of updating the administration and session keys.
