Ad-Hoc网络包括多种网络结构,其中树形结构综合性能最佳,是未来研究的主要方向。树形结构协议包括组密钥协商、成员加入时密钥更新、成员退出时密钥更新、组合并时密钥更新,其中成员退出是树形结构的难点,文章对成员退出协议进行了深入的研究,给出了详细的算法描述和分析描述,并通过复杂的推导得到了最终的有效计算公式,这些工作有助于以后对混合结构的研究。
Ad-Hoc network includes a variety of network structures, of which the best overall performance of the tree structure is the main direction of future research. The tree structure protocol includes group key negotiation, key update when members join, key update when the member exits, key combination update, and the member exit is the difficult point of the tree structure. The article deeply discusses the member exit protocol The study gives a detailed description of the algorithm description and analysis, and through the complex derivation obtained the final effective calculation formula, these efforts contribute to the study of the hybrid structure in the future.
