In this paper we have proposed a scheme which incorporates the concept of modular arithmetic and chaos theory, for image encryption and decryption. In the proposed scheme, we have used chaos theory to generate the necessary random matrix and used the same for Image encryption. For Decryption, we have used look-up table approach to find the element by element modular inverse of the random matrix and use it for decryption of an encrypted image. Our proposed scheme seems to be robust against various attacks.

“…Ganesan et al (Ganesan et al, 2008) described a public key encryption (PKVE) of videos based on chaotic maps. In PKVE, if the number of frames is too large, they first use phase scrambling (see Fig.9) (Nishchal et al, 2003) to scramble the video data, and then encrypt the data using chebyshev maps (Bergamo et al, 2005) (see Equation 17).…”
