Digital chaos has become very popular to provide security. These chaos functions are very useful in encryption process. Researchers have proposed various types of chaos functions and used these chaos functions for multimedia applications like images, audios, and videos. This work analyzes the existing sine-cosine chaotic map, exponent-sine-cosine map, and hybrid chaotic map. This analysis is based on three different parameters like bifurcation diagram, Lyapunov exponent, and Shannon entropy.
