一种基于深度优先的开放网络可信路径搜索方法

Trusted Path-searching Method Based on Depth-first for Open Network

现有的安全解决方案已不再适应开放网络对安全的需求,系统的可信性将逐渐成为研究的趋势。借助消息机制给出了信任在各节点的部署方案;讨论了可信路径搜索的多个细节问题,包括对节点的交互能力和诚实能力的区分,对3个影响因素的分析,及对特殊位置处节点的处理;结合递归的思想,设计了深度优先遍历的可信路径搜索策略,仿真实验结果表明模型与人类社会中的交往关系是相吻合的。

The traditional security solution has not met the needs of open network. Trusted system will be an important research trend in security area. A trust deployment scheme was proposed amongst net nodes based on message mechanism. The problems of trusted path-searching were discussed in detail, including making distinction between interaction and honesty attributes, analyzing three major influencing factors, and dealing with particular position nodes. The newly trusted path-searching strategies were presented with recursive depth-first searching method. Experimental results show the presented model is well conform to the social communication relations.
