摘　　要：自动信任协商是一种在陌生域之间通过互相披露信任证书逐渐建立信任关系的方法 .针对自动信任协商过程中存在的协商效率低、由于披露证书导致的属性敏感信息泄露以及环策略依赖问题,本文提出了一种基于属性敏感度度量的自动信任协商模型(Attribute Sensitivity Measurement-Based ATN,ASMBATN).该模型引入了属性敏感度度量模块,给出了敏感度量化标准,定义了ATN过程中属性敏感度到访问控制策略的映射规则.通过敏感度的值与协商策略的映射关系自动匹配相应的协商策略,简化了自动信任协商策略以及协商过程,提高了自动信任协商的效率,在很大程度上减少了双方的隐私泄露,并且解决了环策略依赖问题.Automated trust negotiation is a method of establishing trust relationship between strangers by mutual disclose certificates.Herein,an automatic trust negotiation model was proposed based on the attribute sensitivity measure to solve the problem of low negotiation efficiency,sensitive attribute information leakage and ring policy dependence.In this model,the attribute sensitivity measurement module was introduced,the quantification standard of sensitivity was given,and the mapping rules of attribute sensitivity to access control policy in ATN process were defined.The corresponding negotiation strategy was automatically matched by the mapping relationship between the value of sensitivity and negotiation strategy.The model simplifies the automatic trust negotiation strategy and negotiation process,improves the efficiency of the automated trust negotiation,reduces the privacy leakage of both parties,and solves the problem of policy dependence.
