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 algorithms are employed nowadays because of their better security and performance aspects. Chaotic behavior of a system is the sophisticated nature of a nonlinear system that looks random. This paper is a review of two novel chaos based image encryption algorithms, namely a secure image encryption algorithm based on Rubik's cube principle and a new chaos-based fast image encryption algorithm in terms of the parameters like NPCR, UACI, entropy and correlation coefficient.
