摘　　要：针对动态网络的间断连通性破坏了组合服务的安全性和可靠性的问题,设计动态网络环境下高延时组合服务网络密钥管理方案(key management in delay and disruption tolerant ad hoc network,KMDTAN)。以稳定性、聚集度、网络规模和连通度作为密钥管理选择标准,在连通区域内根据网络密度设计不同密钥交互协议协商共享密钥,根据稳定性选择共享密钥协商范围,以提高动态网络环境下组合服务的可靠性。理论分析和实验验证了该方案具有较好稳定性和效率性。The intermittent connectivity in dynamic networks destroys the security and reliability of the composed service. To solve the question, a key management scheme for the long time delay service composition of dynamic networks was proposed. The stability, the density, the scale and the connectivity were taken as parameters of the key agreement. In the connected area, different key agreement protocols were designed according to the network density to share the key, and the range of the shared- key agreement was selected. Thereby, the reliability of the service composition in dynamic netwoks was improved. Results of analysis and simulation show the proposed scheme has good stability and efficiency.
