中文摘要: 针对移动P2P网络中的对等端容易耗尽系统资源、受到拒绝服务攻击等问题,提出了一种访问控制框架.在RBAC模型的基础上提出MT-RBAC访问控制框架,模型使用了空间上下文、信任约束和资源控制来实现移动P2P系统的访问控制机制.有效地避免了恶意节点的资源请求对系统资源的消耗,提高了系统可用性.

中文关键词: 移动p2p 访问控制信任模型

Abstract:In order to solve the problem which has existed in the mobile p2p network, for example, the excessive consumption of system resources and the attacks of denial service, a new access control is proposed in this paper. Based on RBAC access control framework, MT-RBAC access control framework adopts the techniques of spatial context, trust constraint and resource control to achieve the access control mechanism of the Mobile P2P System. The new access control framework can effectively and efficiently increase the usability of the system, and prevent the system from the irrational resource request from spite nodes.
