Abstract: With increasing dependence on communications over internet and networks, secure data transmission is coming under threat. One of the best solutions to ensure secure data transmissions is encryption. Multiple forms of data such as text, audio, image and video can be digitally transmitted. Of these, images are the most popular and old encryption techniques such as AES, DES, RSA, etc., shows low security level when used for image encryption. This problem was resolved by using chaos encryption which is an acceptable form of encryption for image data. The sensitivity to initial conditions and control parameters make chaos encryption suitable for image applications. This study discussed and analyzed several chaotic-based image encryption methods and found that changing both the location and value of the image pixels is very important to resist statistical analysis while the use of multi chaotic map leads to increase the key space size, making brute force attack infeasible.
