A Cryptographic Approach for Steganography
Jacques M. Bahi, Christophe Guyeux, Pierre-Cyrille Heam
In this research work, security concepts are formalized in steganography, and the common paradigms based on information theory are replaced by another ones inspired from cryptograp…
Random Walk in a N-cube Without Hamiltonian Cycle to Chaotic Pseudorandom Number Generation: Theoretical and Practical Considerations
Sylvain Contassot-Vivier, Jean-François Couchot, Christophe Guyeux +1
Designing a pseudorandom number generator (PRNG) is a difficult and complex task. Many recent works have considered chaotic functions as the basis of built PRNGs: the quality of th…
A Complexity Approach for Steganalysis
Jacques M. Bahi, Christophe Guyeux, Pierre-Cyrille Heam
In this proposal for the Journèes Codes et Stéganographie 2012, we define a new rigorous approach for steganalysis based on the complexity theory. It is similar to the definitions…
Efficient and Cryptographically Secure Generation of Chaotic Pseudorandom Numbers on GPU
Jacques M. Bahi, Raphaël Couturier, Christophe Guyeux +1
In this paper we present a new pseudorandom number generator (PRNG) on graphics processing units (GPU). This PRNG is based on the so-called chaotic iterations. It is firstly proven…
