摘要
输电线路状态检测是电力物联网建设中的重要应用,针对输电线路在线监测中部署的大尺度、多跳无线传感器网络,设计了一种新的层次化密钥管理方案,对簇进行重新组织,依据新的跳数来生成新的密钥替换过时密钥。通过WSNs分簇中不同的跳数作为密钥管理机制的种子,实现轻量级的动态密钥安全管理。仿真结果表明,该方案不仅具有密钥系统局域化、低能量损耗、不需要特殊节点等特点,而且也提高了网络安全水平。
Absrtact: Transmission line condition detection is an important application in the construction of the power internet of things. In this paper, a new hierarchical key management scheme is designed for the large-scale,multi-hop wireless sensor networks(WSNs) deployed in transmission line on-line monitoring to reorganize clusters and generate new key substitutions based on new hops. By using different hops in WSNs clustering as seeds of key management mechanism, lightweight dynamic key security management is realized. The simulation results show that the scheme not only has the characteristics of localization of key system, low energy consumption and reliance on no special nodes but improves the security safety level.
