The use of the data exchange in e-way along with the tremendous growth in ecommerce and m-commerce has created an intense demand for information security. Information security becomes very significant in data storage and transmission. However, widespread popularity of wireless data communication gadgets, integrated with the availability of higher bandwidths, has led to an increased user demand for multimedia content rich information and images. To make the cipher more robust against any attack, the confidential key created must have high randomness. One has to be very cautious in constructing the cryptographic keys and its algorithm.
