摘　　要：将信任理论引入到路由网络,综合路由实体的安全接入与可靠路由,提出了一种路由模型。该模型以静态可信接入为出发点,通过对路由实体之间的交互行为进行分析,参照复杂网络理论,评估路由实体的接入所带来的网络安全风险及网络增益,对信任关系进行量化,进一步提出了信任度的可靠洪泛算法。同时,提出了一种基于最小信任路由熵的路由算法。该算法能够有效规避信任度低的路由节点,同时兼顾了路由效率。Considering the secure network connection and dependable routing of the routers, a routing model is proposed based on the trust theory. This model takes the trusted network connection as the starting point, and then analyzes the interactive behaviors between routers, referring to the complex theory, and appraisal the network security risk and network gain brought by the connection of the routers entities to quantify the trust relationship. For the second, a dependable flooding algorithm of trust is carried out. At last, a routing algorithm based on the minimum of trust degree routing entropy is presented, which does well in avoiding routers with low trust degree and takes into account the routing efficiency. This model aims to be used in the next-generation connection-oriented Internet which is controlla- ble and trustworthy.
