Abstract: Abstract A new pseudorandom number generator based on piecewise linear chaotic map (PWLCP) was proposed. The proposed scheme can overcome the defect of piccewisc linear when using PWI_CP to generate the pscudorandom sequence. Theoretical analysis and computer simulation indicate that the proposed pseudo random generator has good cryptographical properties.
