P2P网络的准入控制方案

An admission control scheme for P2P Networks

提出了一个P2P网络的准入控制方案。该方案不仅能根据安全需求对节点进行资格审核,屏蔽掉一些不符合安全要求的节点,而且能抵抗Kim等人方案中存在的Sybil攻击和合谋攻击。此外,该方案还具有当节点进入P2P网络后,如有恶意行为,网络能剔除这些恶意节点等特性。

An admission control scheme for P2P networks is proposed in this paper. The scheme not only can audit a new node according to secure requirements and eliminate undesired nodes for P2P networks, hut also withstand Syhil attack and conspiracy attack that exited in Kim et al＇s schemes. Furthermore, when a node＇s malicious actions are found in P2P networks, the malicious nodes would be revoked out from P2P networks.
