服务计算环境下的信任评估模型

Trust evaluation model in services computing

分析了传统信任评估模型,论述了基于信任的扩展SOA模型和信任建模方法,根据第三方代理的推荐信誉看法和团体信誉看法,提出了一种新的服务计算信任评估安全模型(SOC-TrustSM)。SOC-TrustSM在传统信任评估模型的基础上,引入了第一手、第二手、第三手的推荐信誉看法及团体信誉看法,能够较准确地获得服务计算环境下获信代理的信任值,可以有效地抵御代理间的恶意推荐行为。

On the basis of analysis of the traditional trust evaluation model’s advantages and disadvantages,trust concept and trust calculation methods,according to the third party agent reputation and group recommended opinions,this paper proposed a new trust evaluation security model in the environment of service computing（SOC-TrustSM）.On the basis of traditional trust evaluation model,SOC-TrustSM introduced the thought of first or second or third-hand view and group credit view.SOC-TrustSM can effectively evaluate the agency credibility of both sides in the environment of service computing,and resist malicious recommendation behavior of agency effectively.
