Two high capacity text steganography schemes based on color coding
Juvet K. Sadié, Leonel Moyou Metcheka, René Ndoundam
Text steganography is a mechanism of hiding secret text message inside another text as a covering message. In this paper, we propose a text steganographic scheme based on color cod…
A Novel Approach of Pseudorandomly sorted list-based Steganography
Rene Ndoundam, Stephane Gael R. Ekodeck
We propose a new model of steganography based on a list of pseudo-randomly sorted sequences of characters. Given a list of columns containing distinct strings each, wit…
Steganography and Broadcasting
Fabrice P. Tachago, Stephane G. R. Ekodeck, Rene Ndoundam
Informally, steganography is the process of exchanging a secret message between two communicating entities so that an eavesdropper may not know that a message has been sent. After…
PDF Steganography based on Chinese Remainder Theorem
Rene Ndoundam, Stephane Gael Raymond Ekodeck
We propose different approaches of PDF files based steganography, essentially based on the Chinese Remainder Theorem. Here, after a cover PDF document has been released from unnece…
Study of all the periods of a Neuronal Recurrence Equation
Serge Alain Ebélé, Renè Ndoundam
We characterize the structure of the periods of a neuronal recurrence equation. Firstly, we give a characterization of k-chains in 0-1 periodic sequences. Secondly, we characterize…
Period-halving Bifurcation of a Neuronal Recurrence Equation
René Ndoundam
We study the sequences generated by neuronal recurrence equations of the form . From a neuronal recurrence equation of memory size $…
Collision-resistant hash function based on composition of functions
Rene Ndoundam, Juvet Karnel Sadie
cryptographic hash function is a deterministic procedure that compresses an arbitrary block of numerical data and returns a fixed-size bit string. There exist many hash functions:…
Hash function based on arithmetic coding and public-key cryptography
Rene Ndoundam, Juvet Karnel Sadie, Patrick Nguening Nguembu
We propose a hash function based on arithmetic coding and public-key cryptography. The resistance of the hash function to second preimage attack, collision and differential cryptan…
Parallel Chip Firing Game associated with n-cube orientations
René Ndoundam, Maurice Tchuente, Claude Tadonki
We study the cycles generated by the chip firing game associated with n-cube orientations. We show the existence of the cycles generated by parallel evolutions of even lengths from…
