摘要
为了实现无线传感器网络的安全性,提出了一种采用多空间的密钥分配算法,它主要由密钥预分配阶段和密钥协商阶段构成。具体实现是首先基于单空间密钥预分配方案构建出ω个密钥空间,然后每个传感器节点携带来自于τ(2≤τ<ω)个随机选择的密钥空间中的密钥信息,从而从该信息中计算出它们的成对密钥;当两个节点不携带来自公共空间的密钥信息时,它们可以通过接收一个包含节点ID、所携带的空间指标和所携带的种子的广播消息与它们共享成对密钥的其他节点进行密钥协商来计算出它们的成对密钥;仿真结果表明,提出的算法不仅具有低的通信开销,而且在安全性和计算开销方面也优于现有的一些常用密钥预分配算法。
In order to realize the security of wireless sensor networks,a multi-space key distribution algorithm is proposed in this paper,which consists of the key pre-distribution phase and the key agreement phase. The first implementation is that ω key spaces are constructed using single-space key pre-distribution scheme,and then each sensor node carries key information fromτ( 2 ≤τ<ω)randomly selected key spaces. They can compute their pairwise key from the information. When two nodes do not carry key information from a common space,they can calculate their pairwise keys by receiving a broadcast message containing the node’s ID,the indices of the spaces it carries and the seed it carries with other nodes that share the keys. Simulation results show that the proposed algorithm not only has low communication overhead,but also outperforms some commonly used key pre-distribution algorithms in terms of security and computational overhead.
