基于RNG与CBC的异构传感器网络密钥管理方案

Key management scheme for heterogeneous wireless sensor network based on RNG and CBC

为解决异构无线传感器网络密钥管理方案所需负载较大和大规模节点被俘获后的安全隐患问题,提出了一种新的密钥管理方案,采用随机数生成和分组链接技术建立会话密钥,通过在不同簇内广播不同的阶段标志来增加网络的安全性。理论分析和仿真实验表明,该方案能够利用较低的存储负载获得较高的密钥连通性,同时能够解决大规模节点被俘获而带来的安全问题。

For solving the issues of great storage payload and security trouble after mass nodes been compromised in heterogeneous wireless sensor network, this paper proposed a new key management scheme. The scheme took random number generation and cipher block chaining to build a session key. Meanwhile, added different phase signs in different clusters to increase security performance for the whole network. Theoretic studies and simulation experiments show that the scheme needs less storage payload to get more key connectivity and has the ability to solve the security problem after mass nodes been compromised.
