On the Security Analysis of a Hopfield Chaotic Neural Network-Based Image Encryption Algorithm
Table 1
Four common attack types for cryptanalysis.
Attack types
Available resource
Ciphertext-only attack
The attacker only knows the ciphertext
Known-plaintext attack
The attacker knows any given plaintext and also knows the corresponding ciphertext
Chosen-plaintext attack
The attacker can obtain access to the encryption machinery, choose the plaintext that would be useful for deciphering, and also know the corresponding ciphertext
Chosen-ciphertext attack
The attacker can obtain access to the decryption machinery, choose the ciphertext that would be useful for deciphering, and also know the corresponding plaintext
