Simple matlab code for image encryption and learn more about image, encryption, decryption. Secure image encryption algorithms: a review lini abraham, neenu daniel abstract: - image encryption plays an important role in the field of information security most of the image encryption techniques have some security and performance issues so there is a need to compare them to determine which method is suitable for the application chaos based encryption. In recent years, chaos-based image encryption has become an efficient way to encrypt images due to its high security in this paper, we improve the classical quadratic chaotic map to enhance its chaotic properties and use it for image encryption compared with the classical quadratic map, the proposed quadratic map demonstrates better chaotic properties for encryption.
