Toward New Family Beta Maps For Chaotic Image Encryption

Recent research on image encryption algorithms has been increasingly based on chaotic systems, but the drawbacks of small key space and weak security in chaotic cryptosystems are obvious. In this paper, new chaotic maps based on beta function were created. The generation of different pseudo random sequences was carried out to shuffle the position of the image pixels and to confuse the relationship between the encrypted image and the original image, thereby significantly increasing the resistance to attacks. The proposed system has the advantage of high security analysis such as key space, statistical and sensitivity analysis.
