Secure Directed Diffusion Protocol Based on Random Key Predistribution Model

为了解决无线传感器网络中定向扩散协议的安全问题,提出一种基于随机密钥预分布模型的安全定向扩散协议.通过建立安全梯度及应用累积报文鉴别码和多层加密,扩展了定向扩散协议的安全机制,使其能够提供点到点的安全数据通信.安全分析表明,基于随机密钥预分布模型的安全定向扩散协议能够保证定向扩散协议在兴趣扩散、数据传输、路由建立和路径加强阶段的安全性,有效抵御多种由泄密节点发起的攻击.

For solving the security issues of directed diffusion in wireless sensor networks, a secure directed diffusion protocol based on random key predistribution model was proposed, which extends the security of directed diffusion protocol and provides node-to-node secure data communication by setting up secure gradients and applying cumulative message authentication code and multilayer encryption. Security analyses show that the proposed protocol can ensure the security in interest propagation, data propagation, routing setting and path reinforcement phases of directed diffusion, and defend against attacks launched by compromised nodes efficiently.
