| 摘 要： | 综合信任管理和RBAC模型的优势,提出了一种P2P网络环境下基于信任度的动态访问控制模型.该模型通过自动信任协商为用户分配普通角色,在陌生实体间建立动态信任关系,然后网络实时计算用户的信任值,大于信任度阈值的普通角色派生系列带有特权限集的临时角色,临时角色能够访问网络资源,从而实现了细粒度的动态授权策略.

| Abstract: | The trustworthiness-based dynamic access control model is proposed for P2P networks,which integrates the merits of both RBAC(role based access control) and trust management.The model assigns general roles for users by automated trust negotiation to establish the dynamic trust relation among strangers.By calculating the trustworthiness of users,the general roles beyond the trustworthiness thresholds derives temporary roles which possess the privilege sets to access resources.So the model achieves fine-graine... |
