> 中文摘要: 网构软件的构建依赖于对开放协同环境中各种异构的、自治的软件服务实体间的有效协同.Internet的开放性与动态性,使得对于诚实的、具有可靠服务质量协同实体的选择难度较大,难以确保网构软件的可信性.软件实体间的信任关系对于保障网构软件的可信性具有重要的指导意义.软件实体间的信任关系通常随协作的进行而不断变化,但现有的信任模型缺乏对实体间信任关系的自动形成与更新的支持,从而无法刻画信任关系的动态性.针对该问题,提出了一个适用于网构软件的信任度量及演化模型.该模型不仅对信任关系度量过程和信任信息传递及合并过程进行了合理抽象,而且还提供了一种合理的方法,用于促进协同实体间信任关系的自动形成与更新.该模型有助于解决开放环境下网构软件的可信性问题.

Abstract:Internetware is built upon the coordination of the heterogeneous, autonomous software entities in the open coordination environment. But it is very difficult to select the honest coordination software entities with dependable quality of services to build the trusted Internetware because of the openness and dynamic of the Internet. Trust relationships among software entities will provide important information about the selections of trusted coordination entities. The trust relationships are always changing along with the co-operations of software entities. However, the existing trust models cannot support the automatic formation and update of the trust relationships among entities, and cannot reflect the dynamic attribute of the trust relationships. This paper presents a trust measurement and evolution model for the Internetware. The model abstracts the process of the trust measurement, transfer and combination rationally and provides a reasonable approach to form and update trust relationships automatically. This model is helpful to solve the problem of the trustworthiness of the Internetware.
