"Mixed-Signal Hardware Security Thwarts Powerful Electromagnetic Attacks"

The physical hardware in which computationally secure encryption algorithms are implemented may leak sensitive information through electromagnetic radiation. Electromagnetic attacks pose a threat to edge devices that use limited resources, symmetric key encryption, and relatively static secret keys such as smart cards. Therefore, innovators at Purdue University developed hardware technology that uses mixed-signal circuits to reduce electromagnetic and power information leakage significantly. This article continues to discuss recent side-channel attacks, why electromagnetic leakage occurs, and the mixed-signal hardware developed by Purdue's SparcLab team to prevent electromagnetic attacks against Internet of Things (IoT) devices.
