WSN中可撤销自恢复密钥管理方案

Revocation Self-healing Key Management Scheme in Wireless Sensor Network

基于层次型无线传感器网络结构提出一种可撤销、自恢复的密钥管理方案。该方案仅通过一次广播来完成密钥的更新、恢复和撤销功能,同时利用反向哈希链实现认证机制。分析结果表明,该方案在保障安全情况的同时,能实现能量消耗的减少,并提高基于数据融合的无线传感器网络的安全性和可用性。

A revocation self-healing key management scheme in hierarchical Wireless Sensor Network（WSN） is proposed. The key updating, self-healing and the revocation function can be all achieved by only a single broadcast while the authentication mechanism is implemented. The analysis result shows that the scheme can reduce the cost of energy while guaranteeing the security and improves the security and the usability of WSN based on data aggregation.
