Image encryption method based on adversarial nerve cryptography and SHA control chaos

The invention discloses an image encryption method based on adversarial neural cryptography and SHA control chaos, which is based on an adversarial neural cryptography (ANC), a secure hash algorithm (SHA) and an image encryption (IE) algorithm, and comprises the following steps of: inputting all binary hash values of which the SHA is 256 into an image P to obtain a binary hash value; 1) values within the range; according to the method for controlling chaotic mapping by generating the secret key based on the plaintext SHA256 algorithm, the diffusion performance of an encryption system is greatly improved, so that the system can further resist differential attacks, and can resist common attacks such as ciphertext only attacks, ciphertext selection attacks, known plaintext attacks and plaintext selection attacks. The method provided by the invention can be applied to the field of information safety transmission, such as image storage and transmission of Internet, mobile phones and video conferences. 本发明公开了一种基于对抗
