摘要
随着P2P网络的发展与广泛的应用,P2P安全问题也变得越来越复杂,寻找一种可靠的机制来检测与消除各种威胁、攻击和恶意节点的影响便至关重要。论述了将经典的拜占庭将军问题应用到P2P网络安全中的可行性,提出了在实际的P2P网络中应用拜占庭容错的方法,并在局域网中模拟实现,通过对比证实了方法的有效和可行。
With the rapid development and increasing application of P2P networks, security problems in P2P environment become more and more complicated. How to detect and eliminate various threats, attack sources and malicious nodes is a hot research in recent years. In this paper we discuss how it is possible to apply Byzantine Generals Problem （BGP） in a P2P environment to solve such problems, present methods of implement Byzantine Fault Tolerance in real P2P network. Our experiments in a fast local area network show that it performs well.
