一种对等社区网络多层次可靠访问控制机制

A Multi-Level Secure Access Control Mechanism for P2P Community Networks

在P2P计算环境中进行资源的可靠共享需要解决分散于各个节点上的资源的访问控制问题。当前的各种访问控制模型及策略不能很好地适用于P2P计算环境。提出了一种适用于对等社区网络的多层次可靠访问控制机制,可根据节点间关系、资源类别和自身当前策略等因素来灵活设置符合当前需要的访问权限,从而更可靠地实现P2P计算环境中各种资源的充分共享。详细描述了对等社区网络多层次可靠访问控制机制的体系结构、功能模块、工作流程以及相应的实验系统。文中的研究成果为设计更加可靠的P2P软件平台和应用提供了有益的参考。

Sharing of distributed resources in P2P computing environment reliably,the issue of access control needs to be solved firstly,because the current access control models and strategies are not well applied to P2P computing environment.A new multi-level secure access control mechanism is proposed for P2P community networks,which can set required access rights,according to the relationship between nodes,resource types and peer＇s own strategy,etc.,the multi-level secure access control mechanism helps to share resources fully.Describe the architecture,function modules,workflow and the corresponding experimental system of this mechanism.The study result of this paper provides a useful reference for designing more reliable P2P software platforms and applications.
