  • Chaos based Shift Keying for Covert Communication

    -

    A complete Information Security Management Scheme through obscurity was successfully built and tested by generating two chaotic waves using the famous Chua's circuit. Representing 1's and 0's as two asymmetric waves was the core idea of this project, through which the intended information which the recipient needs from the sender was successfully hidden. Statistical analysis was done to analyse the strength of this system. This project resulted in one IEEE conference paper and one journal…

    A complete Information Security Management Scheme through obscurity was successfully built and tested by generating two chaotic waves using the famous Chua's circuit. Representing 1's and 0's as two asymmetric waves was the core idea of this project, through which the intended information which the recipient needs from the sender was successfully hidden. Statistical analysis was done to analyse the strength of this system. This project resulted in one IEEE conference paper and one journal publication.

    This worked formed my bachelor's thesis and I played a significant role of managing all the resultant data and analysing them. I was also incharge of maintaining the project flow and point of contact with the project supervisor
