摘　　要：在以服务为核心的网格计算体系结构中,为了实现信任域之间安全任务调度,服务和用户被赋予信任度标签,利用置信度策略成为解决网格计算资源调度安全的一种手段。基于面向服务体系结构,提出了一种服务资源交换协商的参考模型,来解决跨信任域的服务请求和响应问题。文中首先列举了相关的概念,给出参考模型结构,阐述了跨信任域的服务交换协商安全步骤,最后指出了该参考模型中面临的两个重要问题,为进一步研究基于服务交换的网格服务资源分配模型设定方向。In order to achieve the safe task schedule,the application strategy of confidence-degree endowed by service and user is a way to study in service-centered grid-computing architecture.The paper,on the basis of SOA,provides a reference model of service resource exchange negotiation in different domains to solve the problem of service request and response.h enumerates the relevant concepts,offers the structure of reference model,expounds the steps of service exchange negotiation and even illustrates two important questions confronted by reference model for further research related to the distribution model of grid-computing service resources.
