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.
Key words:
Link-padding,
traffic analysis,
traffic camouflaging
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。
