Bikash Debnath, Jadav Chandra Das, Debashis De, Timam Ghosh · 2016
This paper explores the design of a novel low power encoder circuit for image masking in quantum-dot cellular automata (QCA). The proposed encoder can also function as decoder. Using this mask image, steganalysis is performed to show how an encoded image can be retrieved without knowing the secret key. To establish the low power dissipative nature of the circuit, the power dissipation by the proposed encoder/decoder circuit is estimated. The design accuracy is shown by comparing with the theoretical values of the circuit. Further, operational capabilities are tested under thermal randomness. Implementation is performed through QCA Designer tool and to provide the inputs to the proposed circuit, MATLAB is utilized.
