摘　　要：提出一种基于两跳分簇网络结构的安全合作处理密钥管理协议,能支持无线多媒体传感器网络的合作处理。通过建立簇内和邻簇的密钥对,明显降低了存储开销,解决了密钥对建立和更新过程中通信开销大的问题。性能分析和仿真结果显示,密钥对建立和簇密钥更新通信开销分别减少300%和50%,并有抵制俘获攻击的能力。与不加密直接传输进行比较,加密合作传输的网络性能更优,特别是网络生存周期提高了153%。A Key Management Protocol of Secure Cooperative Processing based on two-hop cluster networking structure is proposed, which supports the Cooperative Processing of Wireless Multimedia Sensor Networks. Through creating the cluster key and the neighbor cluster heads key, the protocol obviously reduces the key storage cost and resolves the problem of high communication cost for key distribution and renewing. The performance analysis and simulation results have shown that the key distribution and the cluster keys renewing cost have been reduced by 300% and 50%, respectively. The protocol can also resist Packet Capture Attack. Compared with the direct transmission without encryption, the performances of cooperative transmission with encryption are well improved. Especially, the life time of the networking can get promoted by 153%.
