摘要
详细分析了地理位置和路由信息对于密钥分发方案的重要性,以及利用K-means算法构造逻辑密钥树的不足,提出一种新的基于路由分支法的节能组播密钥分发方案.实验表明该方案大大减少了组播密钥更新的能耗.
Analyzes in detail that the consideration of the physical location and routing information is critical for developing energy-efficient key distribution schemes,and that the scheme using K-means to construct logical key trees is inefficient.This paper proposes a heuristic rooting branch algorithm for energy-saving multicast key distribution scheme.The simulation results show that new scheme can largely reduce energy consumption of multicast group key update.
