Ronan is a senior security analyst at Riscure in Delft. His work focuses mostly on the security of embedded devices. This consists of both white box and black box evaluations. The work includes things such as code reviews of components like TEE OSs and TAs, penetration tests of mobile phones and other embedded devices, and Fault Injection on high security chips.
Hardware attacks on security relevant components, such as fault injection, have been known for decades and have been shown to be successful on a wide range of devices ranging from general purpose microcontrollers to dedicated security engines. In this work we give an overview of different methods used for fault injection and the effectiveness of these methods. We discuss electromagnetic fault injection in more detail. Most of the published research focuses on attacking low performance secure devices. However, we present the results of electromagnetic fault injection on a modern multicore system on chip running at gigahertz speed and discuss its effectiveness.
