摘要
针对P2PSIP系统面临的Eclipse攻击,提出一种基于双向路由表的防御机制。每个节点同时维护路由表和反向路由表,并周期性地随机审计路由表和反向路由表中的节点,以确保每个节点的入度和出度一致。仿真实验表明,该方法能将路由表污染程度从99%降低到25%左右。
This paper proposes a double-routing table based defense mechanism to mitigate Eclipse attacks on P2PSIP system.Each node maintains a routing table and a reverse routing table.It periodically audits neighboring nodes to ensure compliance with the degree bound.Analysis and evaluation show that this method has promising feasibility and efficiency.In the simulation,the fraction of malicious nodes is reduced from 99% to 25%.
