StegTorrent: a Steganographic Method for the P2P File Sharing Service
Pawel Kopiczko, Wojciech Mazurczyk, Krzysztof Szczypiorski
TL;DR
StegTorrent is a novel steganographic technique for BitTorrent that encodes data by reordering packets without synchronization, achieving high bandwidth and low detectability.
Contribution
It introduces a new packet reordering method for P2P file sharing that does not require synchronization, enhancing steganographic capacity and stealth.
Findings
StegTorrent achieves up to 270 b/s bandwidth.
The method introduces minimal transmission distortion.
It demonstrates high detectability resistance.
Abstract
The paper proposes StegTorrent a new network steganographic method for the popular P2P file transfer service-BitTorrent. It is based on modifying the order of data packets in the peer-peer data exchange protocol. Unlike other existing steganographic methods that modify the packets' order it does not require any synchronization. Experimental results acquired from prototype implementation proved that it provides high steganographic bandwidth of up to 270 b/s while introducing little transmission distortion and providing difficult detectability.
