In this paper, two fatal flaws of the cryptosystem which are based on the logistic map and proposed by Y. Wang and T. Xiang are pointed out. According to this, cryptanalysts could recover the plaintext by the chosen plaintext attacked in a short time. Therefore, the authors propose a remedial improvement which can avoid the flaws and enhance the security of the cryptosystem. (C) 2008 Elsevier Ltd. All rights reserved.
