Cryptanalysis of a new chaotic cryptosystem based on ergodicity

arXiv:0806.3183 · doi:10.1142/S0217979209049966

Abstract

This paper analyzes the security of a recent cryptosystem based on the ergodicity property of chaotic maps. It is shown how to obtain the secret key using a chosen-ciphertext attack. Some other design weaknesses are also shown.
