摘要
针对目前信任协商策略执行效率较低,无法避免策略循环依赖等问题,设计一种基于广度优先搜索的信任协商策略WFS-TNS(Wide-first Search Trust Negotiation Strategy);该策略通过广度优先搜索方式提高信任协商策略的效率,通过安全双方计算解决策略循环依赖问题,并对文章提出的完全敏感资源提供安全防护;经过分析WFS-TNS策略具有安全性、完备性。
This paper focused on the problem of policy cycle dependency and low efficiency in the field of trust negotiation strategy,design a trust negotiation strategy WFS-TNS based on the wide first search method; WFS-TNS improve the efficiency of trust negotiation strategy by the method of wide first search and solve the problem of policy cycle dependency and protection of full privacy by two- SFE; Through analysis WFS-TNS is a secure and complete trust negotiation strategy.
