This book presents the design and analysis of image encryption techniques. Modern cryptography schemes are based on confusion (permutation) and diffusion (change of values) using pseudo random number sequences. We have designed a few Pseudo Random Number Generators (PRNG) and applied them to develop new chaos-based algorithms. Chaotic maps and Linear Feedback Shift Register (LFSR) are used for design of PRNG as they show high randomness and runs on low complexity. It has been found that the strength and complexity of our encryption algorithms are highly depend on quality PRNG used. On the other hand, for diffusion process, techniques like XOR, and DNA computations are used which have very low computational overhead. The designed algorithms are showing promising results even they run with low computational complexity.
