分布式Hash表(distributed Hash table,DHT)是结构化对等网络的核心技术。实际P2P应用中,DHT网络规模已经达到上千万节点,但是其安全问题仍然很多。eclipse攻击是DHT网络中典型的安全威胁之一。本文介绍了DHT网络中eclipse攻击常见的攻击方法,总结归纳了近年来攻击检测和防御技术的研究工作进展,从适用场景、依赖条件和性能等方面对这些工作进行了对比分析,最后对未来的研究工作进行了展望。 Distributed Hash table (distributed hash table, DHT) is the core technology of structured peer-to-peer network. In practical P2P applications, DHT network size has reached tens of millions of nodes, but its security is still a lot of problems. eclipse attacks are one of the typical security threats in DHT networks. In this paper, we introduce the common attack methods of eclipse attacks in DHT networks, summarize the research progress of attack detection and defense technologies in recent years, compare and analyze these tasks from the aspects of applicable scenarios, dependence conditions and performance, and finally analyze the future The research carried out the prospect.
