In the aerospace and defense industries, Rolls-Royce has a heightened concern for the integrity of its supply chain. It must ensure that the parts it acquires from suppliers around the world and the parts that it delivers to customers are genuine articles and not sub-standard or counterfeit parts maliciously introduced into the supply chain by malicious actors.
To evaluate the security of the iTRACE technology, the Rolls-Royce Product Cyber Security Team produced sixteen laser-engraved clones of a genuine iTRACE 2DMI mark. The geometry of the mark was identical for each sample, but during the engraving of each clone, the team made minor variations in one of four laser marking parameters (speed, frequency, wobble frequency, and wobble offset) to test how such manufacturing variation affected the test outcome. Despite using the exact same mark, all sixteen clones failed the authentication test—the iTRACE software correctly identified them as inauthentic and was still able to identify the original and genuine item.
