Secure Clocked QCA logic for implementation of Quantum Cryptographic Processors
Ehsan Rahimi, Shahram Mohammad Nejad · International Conference on Applied Electronics · 2009
Since the introduction of side-channel attacks, cryptographic devices have been highly susceptible to power and electromagnetic analysis attacks; because these attacks require only relatively inexpensive equipments. Unless adequate countermeasures are implemented, side channel attacks allow an unauthorized person to reveal the private key of a cryptographic module. As a new countermeasure a novel logic approach to implement cryptographic processors in, named Secured Clocked Quantum-dot Cellular Automata (SCQCA) logic has been presented. The proposed logic takes advantage of low power consumption Quantum-dot Cellular Automata together with complicated clocking schemes as a paradigm of nanotechnology advances in cryptography engineering.
