摘要: 为在有限资源的无线传感器网络上进行安全的群组通信,组密钥管理在满足基本安全需求的同时,须保证当有节点成员离开或加入网络时,更新组密钥不额外增加系统的通信和计算开销。基于此,使用多项式提出一种安全有效的组密钥管理方案,与现有的群组密钥相比,该方案具有较高的效率,更适合于无线传感器网络。

Abstract: To support secure group communications in resource constrained Wireless Sensor Networks(WSN), and updating group key does not add the commuincation and computing burden of system when sensors leave or enter the system, besides considering the security requirement of group key management must meet, this paper proposes a security and efficient group key management scheme which only uses polynomial. Comparing with previous group key management schemes, this scheme provides more efficiency and is more suitable to WSN.
