Aiming at the security problem of chaos theory in cryptography application, a chaotic block encryption algorithm was designed based on the theory of discrete coupled map lattice and asymptotic deterministic randomness. The algorithm used aymptotic deterministic randomness key to diffuse the plaintext, and through the iteration of the discrete coupled map lattice the plaintext was encrypted. Then the validity, sensitivity and resistance of algorithm were tested and analyzed. The results showed that the security of chaotic encryption algorithm was higher.

    Bipermutive rules are known to induce both expansive and mixing chaotic cellular automata. In this paper, we study some cryptographic properties of bipermutive rules, initially proving that they also satisfy 1-resiliency, which combines balancedness and first order correlation immunity. We thus...
