摘要
为了满足无线网络组播通信的安全,提出一种适用于多跳环境的高效组密钥管理方案.将代理重加密扩展到多跳的无线网络环境中,从而不需要可信的密钥分配中心;在子组的通信中,采用多接收方加密算法,充分利用了无线通信的广播特性,提高了运算效率,大大减少了通信代价.安全分析和效率分析表明,该方案不仅满足前向安全性和后向安全性,而且有效降低了通信复杂度、存储开销和计算量.
For secure group communication in wireless networks, an efficient group key management scheme suited for multi-top environment has been proposed. A proxy re-eneryption to multi-hop environ- ment has been extended, and then a distributed protocol been developed for key distribution. In local group communication, a multi-recipients eneryption has been used to broadcast key information reducing communication cost. Though analyzing the proposed scheme with the previous schemes, the result indicates that the proposed scheme can not only satisfy the forward security and backward security, but also has advantages with regard to the rekeying cost, storage overhead and computation efficiency.
