Algebraic break of a cryptosystem based on discretized two-dimensional chaotic maps
(Elsevier Science BV, 2009-03-30)
Recently, a cryptosystem based on two-dimensional discretized chaotic maps was proposed [T. Xiang, et al., Phys. Lett. A 364 (2007) 252]. In this Letter, we cryptanalyze the proposal using algebraic methods. We give three ...
Comment on "Encryption and decryption of images with chaotic map lattices" [Chaos 16, 033118 (2006)]
(American Institute of Physics Inc., 2008-09)
In this paper, we comment on the chaotic encryption algorithm proposed by A. N. Pisarchik et al. [Chaos 16, 033118 (2006)]. We demonstrate that the algorithm is not invertible. We suggest simple modifications that can ...
