 P2P网络具有动态性、匿名性、可扩展性等特征。由于P2P应用是一种分散的、去中心化、无控制的自发行为,并且具有匿名发布的特性,如何控制信息内容的安全已经成为一个难题。在P2P的网络环境中在基于PKI的多重数字签名的基础上引入对节点的行为特征分析的方法,把节点的行为分为不同的等级。根据不同的等级赋予不同的扣分系数比例,从而使得节点的信誉值更加合理,更好地避免了节点同过获得高信誉值而进行的恶意攻击,从整体上提高了系统的安全性和可靠性。
Abstract:
 P2P(peer-to-peer) networks have dynamics, anonymity, scalability and other features. Because P2P applications are a dispersed, decentralized, uncontrolled spontaneous behavior, and has anonymous release characteristics, how to control the information content of security has become a problem. In the P2P network environment, the behavioral characteristics of the node analysis method were introduced on the basis of multiple digital signatures based on PKI, and assorted the behavior of the nodes into different grades. According to different levels, it gave a different coefficient of the ratio points, made a more reasonable value of the node’s credibility, and better avoided the nodes with high reputation values to get malicious attacks. It improved system security and reliability on the whole.
