WSNs中基于密钥共享的安全路由

Secret key sharing-based security routing in Wireless Sensor Networks

摘要:

针对无线传感网络的安全路由，提出能效和安全多跳路由(ESMR)。ESMR路由通过密钥共享策略，提高路由防御恶意节点的性能。ESMR路由先依据节点的位置将网络划分不同区(Zone)，在每个Zone内，依据邻居节点位置划分多个簇；然后，每个Zone的簇头向基站传输数据，并依据密钥共享策略对数据进行加密。仿真结果表明，相比于同类路由，提出的ESMR在网络寿命、吞吐量、能耗以及端到端时延方面的性能得到有效提高。

Abstract:

For secure routing of Wireless Sensor Networks(WSNs), Energy-aware and Secure Multi-hop Routing(ESMR) is proposed. ESMR protocol increases the performance of energy efficiency with multi-hop data security against malicious actions. The network field is segmented into inner and outer zones based on the node location. Furthermore, in each zone, numerous clusters are generated on the basis of node neighborhood vicinity. Secondly, the data transmission from cluster heads in each zone towards the sink node is secured by using the proposed efficient secret key sharing scheme. The experimental results demonstrate the efficacy of proposed ESMR in terms of network lifetime, network throughput, energy consumption, average end-to-end delay in comparison with the existing work.
