Abstract:Collision Attack (CA) has posed a huge threat to the security of AES circuit. To protect sensitive information, it’s necessary to do research on defense strategy of CA. This letter proposes a new method to defense CA through the implementation of random delay based parallel S-box. It can destroy the consistency of the power consumption curves, confuse the judgment of the collision and the setting of the collision threshold to achieve the goal of resisting the CA. Compared to the well-known random mask method and other CA countermeasures, our strategy can defense CA without changing the AES round transformation architecture and bring extra resource overhead. © 2019 The Institute of Electronics, Information and Communication Engineers.
