摘要
This paper studies the security of a recently proposed chaos-based cryptosystem. It is shown that the encryption architecture of this cryptosystem exhibits some important problems related to its implementation and its robustness against noise. Some security problems are also highlighted. (c) 2010 Elsevier B.V. All rights reserved.
