> The digital images can be converted to binary data and encrypted with Advanced Encryption Standard (AES). However, the high correlation between adjacent pixels may still be kept after encrypting a digital image without considering the property of digital images.
What do you mean by this? It sounds like it’s suggesting that, e.g., the AES-CBC ciphertext of an image has detectable internal correlations. In other words, AES is completely broken as a cipher. Surely I’m misinterpreting the claim here.
