On Public-Key Steganography in the Presence of an Active Warden [chapter]

Scott Craver
1998 Lecture Notes in Computer Science  
The so-called prisoners' problem, in which two individuals attempt to communicate covertly without alerting a "warden" who controls the communications channel, has taken a number of forms, adorned with  ...  This technique is possible through the use of two distinct channels rather than one: the subliminal channel for steganographic communication is augmented by a supraliminal channel, one in which information  ...  The prisoners' problem The prisoners' problem was first posed by G.J. Simmons in 1983 , and is generally considered to be the de facto model of covert communication.  ...

A novel group signature scheme with subliminal channel

Jian-hong Zhang, Peng-yan Li, Xu-bing Zhao
2016 Wireless Communication and Sensor Network  
Secondly, we evaluate Jan-Tseng signature schemes with subliminal channel in ICPP'99 and show that any user can change the signature, such that the subliminal message receiver cannot get the subliminal  ...  The subliminal channel in a cryptographic protocol such as an authentication system or a signature scheme provides an additional channel from the sender to an authorized receiver and can't be read by any  ...  For instance, in the prisoners problem [13] or credit card application, the wardenry or the card holder doesn't hope there is some subliminal channel in their messagesignature pairs.  ...

On the Existence of Subliminal Channel in Instant Messaging Systems

Lingyun Xiang, Yuhua Xie, Gang Luo, Weizheng Wang
2015 International Journal of Security and Its Applications  
The broad-band subliminal channel can be established in Skype and QQ messages. Therefore, two subliminal channel schemes are proposed to embed and extract subliminal information.  ...  Finally, performances of the proposed subliminal channels are compared with those of the ones based on ElGamal digital signature and Newton channel.  ...  For the warden in the Prisoners' problem introduced by Simmons [1] , the randomness of a cryptosystem mainly includes three categories: 1) the stochastic parameters inputted from the cryptosystem, such  ...

Special Uses and Abuses of the Fiat-Shamir Passport Protocol (extended abstract) [chapter]

Yvo Desmedt, Claude Goutier, Samy Bengio
1988 Lecture Notes in Computer Science  
A non-trivial solution to avoid these subliminal channel problems is presented. The notion of rehtiue zero-knowledge is introduced.  ...  Using an extended notion of subliminal channels, several other undetectable abuses of the Fiat-Shamir protocol, which are not possible with ordinary pssports, are discussed.  ...  The last one however agrees that the prisoners may authenticate the communication. Simmons explains how a subliminal channel can be set up [17] .  ...

A traceable E-cash transfer system against blackmail via subliminal channel

Chin-Ling Chen, Ming-He Liu
2009 Electronic Commerce Research and Applications  
Now, more and more digital signature applications use a subliminal channel to transfer secret messages.  ...  The subliminal channel is the most popular method, which notifies the designated receiver to transmit secret messages. Simmons was the first to propose this concept in 1983.  ...  Acknowledgements We thank the reviewers for their insightful comments which helped to improve this paper significantly.  ...

From 'Steganographia' to Subliminal Communication [chapter]

Otto J. Horak
1995 IFIP Advances in Information and Communication Technology  
Subliminal channels as a special kind of covert channels, its detection and realization in digital signatures are shown as the most recent examples.  ...  This period starts with mass applications of digital computers in the early 1970s. Steganography now appears as covert channel in information processing, storage and communications.  ...  A classical example of a covert channel was the scheme used by some American prisoners of war during WW II to conceal information from enemy censors by causing the sequence of dots to the letter "i" and  ...

A Subliminal Channel in Secret Block Ciphers [chapter]

Adam Young, Moti Yung
2004 Lecture Notes in Computer Science  
It is a broadcast channel that assumes that the sender and the receiver know the subliminal message ms (i.e., something derived from their common key).  ...  In this application, the secret block cipher securely and subliminally transmits the symmetric key of the sender and receiver to the malicious designer and confidentiality holds even when the cipher is  ...  Subliminal Channels and Backdoor Ciphers To show that the notion of a subliminal channel was applicable in practice, the prisoner's problem was devised [21] .  ...

Hernandez-Castro for their helpful suggestions. Furthermore, authors would like to thank the anonymous reviewers for their valuable comments.  ...
