一种基于信任的P2P接纳控制方法

摘要

当前P2P系统的研究集中在P2P内部节点的信誉排名问题上，从节点如何进入系统的角度提出了一种P2P节点的接纳控制方法。该方法基于节点自身经验及好友节点的推荐对申请加入节点进行判断，模拟实验表明该方法对新节点加入系统进行了有效控制，而且系统扩展性很好，同时也阻止了部分恶意节点进入系统。%In P2P network area, the current studies focus on the reputation rankings for internal nodes of P2P.However, this paper proposes an admission control method for those nodes who apply to join the P2P system. This method judge nodes who apply to join based on experience and friend nodes’s recommended of nodes who have been applied. Simulation experiments show that, with our method, it can not only effectively control the nodes who new added, but also possess very good scalability, on the other hand, it also protect the system from malicious peers.
