摘要 由于传统的密钥管理技术不太适合资源受限的无线传感器网络,因此在保证网络生存周期条件下如何进行密钥预分布和建立成为传感器网络的安全技术研究的一个重要目标.文中提出了一种新的低功耗密钥预分布方案(Low-power Key Pre-distribution Scheme,LKP).该方案把密钥池中的密钥分成具有内在联系的密钥链,前后相邻的密钥链中的密钥以一定概率重叠,每个节点均密钥链的首密钥、重叠密钥部分的初始密钥和初始位置,然后根据密钥链的重叠度来寻找最佳的网络连通性,最后分析了LKP方案的安全性,并从节点的能量损耗、安全方面对LKP方案进行性能仿真.结果表明,LKP方案与q-composite随机密钥预分布方案、多路密钥增强方案相比,降低了能量消耗,增强了网络的安全性能. Key establishment and management in wireless sensor networks are one of the important targets of security technology researches because traditional key cryptosystems are unsuitable for resource constrained sensor nodes. A novel scheme named Low-power Key Pre-distribution Scheme （LKP） was proposed. This scheme generated a combination of inherited key chain, stored the head key of the key chain and the first key of overlay of keys into each node, searched for better network connectivity between nodes according to the overlap of keys, and then analyzed the security of the LKP scheme. At last the performances of the LKP scheme such as energy consumption and capture probability were simulated. The results show that LKP scheme is better than q-composite random key pre-distribution scheme and multi-path key reinforcement scheme on security and energy.
