传感器网络中一种分布式组密钥管理方案

无线传感器网络需要安全组通信的支持,尤其是军事、紧急救灾等场合。然而由于传感器网络自身资源的限制,使得传感器网络的组密钥管理面临巨大的挑战。基于门限秘密共享机制和组密钥分量更新机制提出了一种分布式组密钥管理方案。分析结果表明,该方案具有较高的安全性和较小的网络开销。

A Distributed Group Key Management Scheme for Sensor Networks

Many emerging Wireless Sensor Networks applications especial for emergency and military situations depend upon secure group communications.But group key management in WSN faces a great challenge because of the resources are constrained.Based on the thresh-old secret sharing mechanism and group key share refresh mechanism,a distributed group key management scheme is proposed in this paper.Analysis results demonstrate that the scheme has good security performance and lower network overheads.
