A New Image Encryption Algorithm Based on Chaos and Secure Hash SHA-256

A New Image Encryption Algorithm Based on Chaos and Secure Hash SHA-256

In order to overcome the difficulty of key management in “one time pad” encryption schemes and also resist the attack of chosen plaintext, a new image encryption algorithm based on chaos and SHA-256 is proposed in this paper. The architecture of confusion and diffusion is adopted...
