Noise-resisting ciphering based on a chaotic multi-stream pseudo-random number generator

International audienceWe propose a novel noise-resisting ciphering method resorting to a chaotic multi-stream pseudorandom number generator (denoted Cms-PRNG). This Cms-PRNG co-generates an arbitrarily large number of uncorrelated chaotic sequences. These cogenerated sequences are actually used in several steps of the ciphering process. Noisy transmission conditions are considered, with realistic assumptions. The efficiency of the proposed method for ciphering and deciphering is illustrated through numerical simulations based on a Cms-PRNG involving ten coupled chaotic sequences
