| 摘 要： | 安全有效的路由算法是P2P网络的关键技术之一.针对目前大多数P2P路由算法没有考虑安全性问题,并且采用随机选择下一跳节点的方法会降低路由效率,给出了一种新的P2P安全路由算法.该算法采用信任度与路径可靠性指导下一跳节点的选择,以建立安全有效的路由路径,并且引入加密、多路径传输等方法以抑制篡改、窃听等典型攻击.模拟实验结果表明,该路由算法的路由效率要优于Gnutella,安全性能好.

| Abstract: | Secure and effective routing algorithm is one of vital technique for P2P network. Most of P2P routing algorithms don＇ t take the secure＋ problem into account, and choosing the next hop node randomly would decrease greatly the efficiency of rou- ting. A new P2P routing algorithm is proposed in the paper. It adopts trust and the reliability of path to guide choosing of the next hop node, the secure and effective routing path is established, and the transmission of muhipath and encryption can effectively re- strain several typical security attacks such as tamper and tapping. The results of experiment show that its efficiency of routing is better than Gnutella, and its security is nicer. |
