摘要: 在计算机通信网中,窃听者能够从通信序列的统计特征中获取信息,发动流量分析攻击,由此造成链路情况的机密泄漏。该文提出了基于IP的以太网Link-padding流量伪装方法并设计出其原型,借助Libnet,Libpcap和OpenSSL的C语言库,在Linux系统上已对其进行了基本实现。

Abstract: In computer communication networks, traffic series contain statistical patterns that are useful for eavesdropper to collect information for launching traffic analysis attacks. This paper presents a system scheme and a prototype to prevent traffic analysis in IP-based Ethernet based on link padding methodology. The prototype is built on a Linux machine by using three C language libraries, namely, Libnet, Libpcap and OpenSSL.
