A class of one-dimensional piecewise linear(PWL)chaotic system is proposed in this paper.This system is capable of generating chaotic signals with uniform distribution and δ-like auto-correlation fonction. It is shown that these signals can be ed to provide binary chaotic ciphers via non-invertible transformations. Moreover
the finite precision effect of the proposed PWL chaotic systems is investigated
and m-sequencebased peturbation approach is proposed. Comparing with traditional stream encryption methods
chaotic stream ciphers are not only abundant in number
