摘　　要：提出了一种能有效应对网络内部节点攻击的基于信任度的多路径安全路由方法.在可达路径搜索时基于广度优先的基本思路,配合边缘节点优先、短路径优先的启发原则进行优化减枝,实现快速的节点独立多路径搜索.利用跨层信息对节点信任度和路径信任度进行判断和计算,基于可达路径的信任度,设计了多路径单传输MPST和多路径多传输MPMT两种机制完成信息传输.仿真结果表明,所提出的多径安全路由方法能有效提升网络分组传输的性能以及应对网络潜在的漏检恶意节点.This paper proposes a confidence degree based multi-path secure routing method which can deal with internal attack effectively.The feasible paths searching is implemented by fringe node first and short path first heuristic method based on breadth-first principle.The confidence degrees of nodes and paths are calculated with cross-layer information,and the multi-path single transmission mechanism and the multi-path multi-transmission mechanism are designed to accomplish the information transmission.Simulation results show that the proposed multi-path secure routing method can increase the network packets transmission performance and deal with the potential miss-checking malicious nodes effectively.
