一种UC匿名的移动自组网概率组播策略

A Probabilistic Multicast with Universally Composable Anonymity in MANETs

鉴于现有移动自组网匿名路由协议不能为组播提供匿名通信支持,而只能提供特定非形式化的匿名性分析,提出了一种UC(universally composable)匿名的移动自组网概率组播策略.在路由发现阶段,采用一次性密钥对保持路径记录私密.在数据分组传输阶段,采用Gossip机制、DH秘密路径及Bloom Filter编码实现匿名源路由组播.最后,采用UC框架分析了协议的匿名性,并对协议的性能进行了仿真.分析与仿真结果表明,该策略在实现匿名性的同时还提供了较好的可靠性.

Current anonymous routing protocols do not provide anonymous mechanism for multicast in MANETs and have only had ad-hoc anonymity analysis. This paper proposes a new scheme called probabilistic multicast with universally composable anonymity. One-Time key pair is used to keep a route record in privacy during route discovery processes. Gossip-Scheme, secret DH path and Bloom Filter are adopted to realize anonymous source multicast during transmission of data packets. Finally, the protocol is analyzed based on the UC （universally composable） framework and its performance is evaluated by simulation. The analysis and simulation results show that the proposed scheme provides both anonymity and reliability for multicast in MANETs.
