IP加密数据包的隐写技术

Steganography in Handling Oversized IP Packets

Wojciech Mazurczyk, Krzysztof Szczypiorski

摘要:

本文确定了一类新的网络隐写方法,利用机制来处理IP网络中的超大数据包:IP分片,PMTUD(路径MTU发现)和PLPMTUD(分组化层路径MTU发现)。特别是,我们提出了两个新的隐写方法和现有的两个扩展。我们展示了如何IP碎片简化利用隐写方法,需要发送器-接收器同步。我们提出了如何使用上述机制来实现两个版本的IP协议的隐藏通信:4和6。本文还对所提出的方法进行了检测。

英文摘要:

This paper identifies new class of network steganography methods that utilize mechanisms to handle oversized packets in IP networks: IP fragmentation, PMTUD (Path MTU Discovery) and PLPMTUD (Packetization Layer Path MTU Discovery). In particular, we propose two new steganographic methods and two extensions of existing ones. We show how IP fragmentation simplifies utilizing steganographic methods which requires transmitter-receiver synchronization. We present how mentioned mechanisms can be used to enable hidden communication for both versions of IP protocol: 4 and 6. Also the detection of the proposed methods is enclosed in this paper.
