摘要
In this paper, a modified method of a class of recently proposed cryptosystems is presented. As a remedy, the piece-wise linear chaotic map (PLCM) which has a uniform distribution is adopted in our method. The experimental results demonstrate that the application of PLCM can not only ensure the feasibility but also promote the encryption speed of these cryptosystems. Moreover, a new design of dynamical look-up table is used as an efficient way to ensure the security of our cryptosystem. (C) 2004 Elsevier Ltd. All rights reserved.
