Biao Wang, Hengjian Li · 2018
The traditional chaotic mapping encryption algorithm has the disadvantage of being vulnerable and insecure. Therefore, in order to improve the anti-attack capability and security of encryption system, an improved image encryption Method-plaintext association scrambling image encryption algorithm is proposed. The encryption process consists of two diffusion algorithms and a scrambling algorithm, and the inverse of the encryption process is the decryption process. The simulation results show that the system can obtain better encryption effect, and the security is higher than the traditional encryption algorithm.
