M. Tech. Electrical Engineering. / Proposes a public-key encryption scheme based on Qi hyperchaos, which is considered much better than chaos and other hyperchaos in terms of pseudo-randomness. In an environment where digital information is being extensively used, a cat map based hyperchaotic system is proposed. This map is used to design the public key encryption scheme that uses private keys, public keys and shared private keys. This encryption is tested successfully on text messages and images. The application of the hyperchaos-based scheme on a web server client platform concludes this work. MATLAB is used for simulation. PHP, HTML, and C are used in the development of the web form and the chat application.
