网格环境下信任关系的研究

Reaserch on Tust Relation in Grid

随着网格应用的不断深入,安全成为网格计算研究应用的焦点,特别是用户的多种需求以及网格资源的异构性使得安全变得尤为重要,缺乏安全保证逐渐成为制约网格应用的瓶颈之一。虽然很多学者进行了大量的研究,但由于忽视信任机制的影响,大大降低了服务质量。所以,本文引入信任机制对网格服务进行研究,以期提高服务安全。

With the continuous deepening of grid applications,security is the focus of researches in grid computing environment.Especially,the multiplicity of users＇ demands and the heterogeneity of grid resource make security most important.Lacking of security is becoming one of bottlenecks in grid applications.Although many researchers makes much study,ignoring the impact of trust mechanism can make reduce quality of service greatly.So this paper researches grid quality of service problems adding trust mechanism to improve quality of service.
