A pseudorandom bit generator based on mixing of state variable of CML

In recent years, chaos-based cryptography is widely studied, especially in the field of pseudorandom bit generators. The paper describes a novel pseudorandom bit generator (PRBG) based on chaotic couple map lattice. The state variables of the couple map lattice are combined to produce a block of 32 random bits at each iteration. Various experiments are carefully conducted to evaluate the quality of the proposed pseudorandom bit generator. The...
