A secure arithmetic coding based on Markov model
چکیده انگلیسی

We propose a modification of the standard arithmetic coding that can be applied to multimedia coding standards at entropy coding stage. In particular, we introduce a randomized arithmetic coding scheme based on order-1 Markov model that achieves encryption by scrambling the symbols’ order in the model and choosing the relevant order’s probability randomly, which is done with higher compression efficiency and good security. Experimental results and security analyses indicate that the algorithm can not only resist to existing attacks based on arithmetic coding, but also be immune to other cryptanalysis.
