摘要
针对分簇无线传感器网络(wireless sensor network,WSN)能量不均衡、连通率低和效率低等问题,提出一种方形环状密钥管理方案,详细描述了密钥管理全过程,包括:初始化、簇节点身份信息(identity document,ID)、簇间密钥管理、簇内密钥管理、节点通信、密钥更新和节点加入与退出等。其中,簇间密钥管理使用改进椭圆曲线迪菲-赫尔曼密钥交换(elliptic curve Diffie-Hellman key exchange,ECDH)的密钥协商方案,簇内密钥管理使用基于中国剩余定理的密钥分配方案。形式化安全分析证明方案的正确性和安全性,对多种已知攻击的非形式化分析证明方案可抵抗各种安全攻击;能耗分析表明方案具有较低的存储、计算和通信开销。因此,该方案在兼顾安全性的同时能有效降低能耗,适用于资源受限的WSN。
Aiming problems of energy imbalance,low connectivity and low efficiency in clustered wireless sensor networks(WSN),a square ring key management scheme is proposed.The whole process of key management is described in detail,including initialization,cluster Identity Document(ID),inter-cluster key management,intra-cluster key management,node communication,key update,node joining and exiting,etc.Among them,the key agreement scheme of the improved Elliptic Curve Diffie-Hellman key Exchange(ECDH)is used for the inter-cluster key management,and the key distribution scheme based on the Chinese Remainder Theorem is used for the intra-cluster key management.Formal security analyses prove the correctness and security of the scheme,and non-formal analyses prove that the scheme can resist various security attacks against multiple known attacks;Energy consumption analyses show that the scheme has lower storage,computation and communications costs.Therefore,the scheme can effectively reduce energy consumption while taking security into account,and is suitable for resource-constrained WSNs.
