Cryptanalysis of Novel Image Encryption Scheme Based on Multiple Chaotic Substitution Boxes by Ammar S. Alanazi, Noor Munir, Majid Khan, Muhammad Asif, Iqtadar Hussain

“…The proposed attacks are successfully performed to retrieve the key with very little execution time by using just one chosen image which indicates the vulnerability of multiple chaotic S-boxes-based cryptosystems. The retrieved data is passed through some statistical analysis such as correlation, histogram, and entropy to check the correctness of recovered data.…”
