摘要
This paper describes the security weakness of a recently proposed secure communication method based on discretetime chaos synchronization. We show that the security is compromised even without precise knowledge of the chaotic system used. We also make many suggestions to improve its security in future versions. (C) 2003 Elsevier Ltd.
