Abstract

In an unreliable environment such as global computing, resource providers are faced with the problem of making decision autonomously with partial information before providing services for resource requesters. Although many trust management models have been proposed to deal with security concerned in resource service, few of them take risk into consideration. In those schemes involving risk, either risk is discussed conceptually, or methods for calculating risk and trustworthiness are not described clearly. This paper presents a risk-aware resource service decision strategy for global computing. The paper not only explores the pivotal source of risk and the relationship between trust and risk, but also quantifies risk to facilitate the resource service decision. The paper proposes the reputation inference based on probability theory and risk degree algorithm based on Chernoff Bound theorem. In the simulation, the performance of our risk-aware resource service decision strategy is evaluated.
