摘要： 目前多数Ad hoc网络中的组播密钥管理协议都是为了提高某一方面的代价而牺牲其他方面的代价,这与Ad hoc网络对带宽和计算资源的要求相矛盾.为解决这一矛盾,提出了新的分布式组播密钥管理方案,即基于双线性配对密钥树的TPAN协议.TPAN密钥树结合了PSTR方案和PTGDH方案的优点,在主干网络中使用了PSTR密钥树的结构,在部分节点分枝为PSTR密钥子树或PTGDH密钥子树.经过对协议通信代价和计算代价的比较及安全性分析,结果表明,该方案在通信代价和计算代价之间达到了平衡,都具有较小的代价,并且是安全的.

Abstract: Most of the ad hoc network group key management protocols are often improved in some respects at a great cost in other respects, since there is a contradiction between bandwidth and computation resources in ad hoc network. A new distributed group key management protocol is therefore proposed and named TPAN protocol, i.e., a tree-based group key agreement using bilinear pairing for mobile ad hoc networks, which combines the merits of both PSTR and PTGDH together. In TPAN the PSTR key tree is taken as the trunk with the PSTR or PTGDH protocol as branches or sub-trees. The communication costs and calculating costs of different protocols are compared with each other and their security is analyzed, and the results show that the TPAN protocol can achieve the balance between computation costs and communication costs with low costs and security provided.
