一种分簇无线传感网轻量级匿名认证及密钥协商方案

A Lightweight Anonymous Authentication and Key Negotiation Scheme for Clustered WSN

针对分簇无线传感网中的节点认证问题,使用轻量级的哈希函数和异或运算,设计了一种节点认证及密钥协商方案,将匿名机制引入节点认证过程中,保护了节点隐私安全,提高了网络抵御流量分析攻击的能力.对认证方案抗攻击性能和资源开销的对比分析结果表明,提出的方案可以提供良好的安全认证,并具有较低的计算、存储和通信开销.

Focusing on the nodes authentication problem of clustered wireless sensor network,the paper proposes a lightweight authentication and key negotiation scheme using hash function and exclusive or（ XOR） operation. The anonymity mechanism is introduced into the authentication process,which can thwart the traffic analysis attacks,and protect the privacy of nodes. In addition,by analyzing and comparing the anti-attack performance and the resource overhead of the authentication scheme,the results show that the proposed scheme can provide good authentication and also have a lower overhead at the cost of computation,storage and communication.
