Journal ArticleDOI
Image encryption using block cipher and chaotic sequences
TL;DR: In this article, a randomized block ciphers inspired by the Rijndael architecture employing chaotic maps as an entropy source is proposed, which achieves good security and robustness indicators.
Journal ArticleDOI
Modeling Fading Channels With Binary Erasure Finite-State Markov Channels
TL;DR: An enumerative technique to analytically evaluate the performance of a linear block code over the ternary Markov channel (TMC) and a new recurrence expression is developed for calculating the probability of codeword error for bounded distance error and erasure decoding.
Journal ArticleDOI
Emitter-coupled pair chaotic generator circuit
TL;DR: An emitter-coupled pair chaotic generator is proposed with a control parameter that can be tuned for distinct chaotic behaviors that passes all NIST statistical tests by applying a post-processing to the balanced bit sequence generated by a quantization of the circuit output.
Journal ArticleDOI
A smooth chaotic map with parameterized shape and symmetry
TL;DR: A new measure, namely, the spread rate, is proposed to study the local structure of the chaotic dynamics of a one-dimensional chaotic map, and it is demonstrated that the Lyapunov exponent of the tanh map is robust, remaining practically unaltered with the variation of its parameters.
Journal ArticleDOI
Digital Communication Systems Based on Three-Dimensional Chaotic Attractors
TL;DR: A methodology to design chaos-based communication systems, which exploits the topological structure of 3-D chaotic attractors, and the evolution mechanism of the chaotic attractor is represented by a state diagram.
