摘要
针对目前网格环境下域间管理存在可扩展性、动态适应性差的现状,提出一种基于信誉担保的网格域成员关系管理模型DMRGGD。建立基于信誉值的网格域信誉担保的推荐模型,为新加入的域成员在不依赖中心服务器的情况下建立初始信誉值,在域成员间通过计算直接信任度和多路径间接信任度,实现动态更新信誉值和评估信任关系,通过担保人信誉连带责任制,防止恶意担保。
To solve the management problem of lacking extensibility and dynamic adaptability in grid domains, this paper puts forward Dynamic Model Based on Reputation-Guarantee in Grid Domains（DMRGGD）. In order to join the grid domain and construct the trust with others without the central server for the new domain member, it presents the domain recommendation model based on worthiness. The relations are evaluated and the worthiness is updated for domain members dynamically by computing the direct reputation and indirect reputation of multipath. With the joint responsibility for guarantor, the model is able to prevent malicious guarantee.
