摘要 针对现有密钥协商协议没有考虑Ad hoc认知无线电网络多信道这一缺陷,提出一种多信道密钥协商协议(multi channels key agreement protocol,MCKAP),通过建立多重图和替换广播操作减少信道冲突,优化协商路径提高共享密钥协商效率,利用信道属性为节点间选择合理位置,避免主用户干扰。该方案能有效地利用多信道提高共享密钥协商效率。最后通过理论分析和仿真实验证明该协议适用于Ad hoc认知无线电网络,具有较好的执行效率。

英文摘要 Current key agreements are not suit to the multi-channel cognitive radio networks. In order to deal with the question, this paper put forward the multi channels key agreement protocol (MCKAP), which reduced the confliction and improved the operations among channels with building the multi-graph on network and replace the broadcast operations. And it put forward node selection algorithm to reduce the conflictions from primary users. Theory analysis and experiments prove that this scheme is suit to the Ad hoc cognitive radio networks.
