doi:10.3969/j.issn.1671-1122.2021.12.012

Abstract

Abstract:

This paper proposes a police image encryption algorithm based on the combination of asymmetric encryption and the cellular neural networks encryption. It uses the chaotic random sequence generated by the chaotic system of cellular neural networks to encrypt the police image, and uses the asymmetric encryption algorithm to protect the input key value of the chaotic system. The experimental results show that this algorithm is simple, and have large key space with strong sensitivity. It has high security and high robustness for the encryption and protection of police images, and has a good prospect of utilization.

Key words: cellular neural networks, chaotic system, asymmetric, police image, encryption
