Abstract:
System-on-Chips (SoCs) are a key enabling technology for the Internet-of-Things (IoT), a hyper-connected world where on- and inter-chip communication is ubiquitous. SoCs usually integrate cryptographic hardware cores for confidentiality and authentication services. However, these components are prone to implementation attacks. During the operation of a cryptographic core, the secret key may passively be inferred through cache observations. Access-driven attacks exploiting these observations are...     »
