The Mechanism to Combat Data Leakage Trojans in Circuits using Ranomized Encoding

Abstract

For any system dealing with data, security is an essential factor. With increasing manufacturig and production costs, many companies rely on external facilities. There is a chance of Trojan insertion in such a situation. In the paper, the Randomized Encoding of Combinational Logic for Resistance to Data Leakage (RECORD) technique is explored. Data randomization is carried out in this technique that renders the leaked data useless in the event of a Trojan attack. The percentage of randomization and recovery obtained is taken into consideration to assess the design efficacy. Design analysis on combinational circuits for a given set of inputs provided randomization of 50% and efficient data recovery. The design study of the RECORD method when extended to sequential circuits provides randomization of 40% and 100% recovery for an appropriate sequence of random bit change at every clock cycle.
