StegFS: A Steganographic File System
While user access control and encryption can protect valuable data from passive observers, those techniques leave visible ciphertexts that are likely to alert an active adversary to the existence of the data, who can then compel an authorized user to disclose it. This paper introduces StegFS, a steganographic file system that aims to overcome that weakness by offering plausible deniability to o...
متن کاملTraffic Analysis Attacks on a Continuously-Observable Steganographic File System
A continuously-observable steganographic file system allows to remotely store user files on a raw storage device; the security goal is to offer plausible deniability even when the raw storage device is continuously monitored by an attacker. Zhou, Pang and Tan have proposed such a system in [7] with a claim of provable security against traffic analysis. In this paper, we disprove their claims by...
متن کاملAnalysis and Implementation of Distinct Steganographic Methods
In this paper, different steganographic methods have been analyzed and implementations of those techniques have been performed. Those methods include hiding in text, hiding in audio file, hiding in file system, and hiding in image files.
متن کاملA Shared Steganographic File System with Error Correction
Steganographic file systems are file systems where the location and even the existence of files are unknown to the users not having stored them. If the file system can be written to by several users, a user may inadvertently damage the files stored by other users. In this paper, solutions to the collision problem are proposed which rely on errorcorrecting codes. The storage efficiency and the p...
متن کاملStegFS: A Steganographic File System for Linux
Cryptographic file systems provide little protection against legal or illegal instruments that force the owner of data to release decryption keys for stored data once the presence of encrypted data on an inspected computer has been established. We are interested in how cryptographic file systems can be extended to provide additional protection for such a scenario and we have extended the standa...
