TGDH协议的分析与实现
Design and Implementation of TGDH Protocol
【摘要】 基于成员离开概率对TGDH协议进行优化。证明当密钥树为Huffman时,改进后的P-TGDH协议中,平均成员密钥更新量和平均指数运算时间开销均可达到最优。
【Abstract】 We improve TGDH protocol based the probability of members leaving.When using Huffman tree as the key tree,this paper proves that the average cost of re-keying and the average time cost of exponentation computation of each member is optimal in P-TGDH protocol.
