When Memory Mappings Attack: On the (Mis)use of the ARM Cortex-M FPB Unit
Haoqi Shan, Dean Sullivan, Orlando Arias
In recent years we have seen an explosion in the usage of low-cost, low-power microcontrollers (MCUs) in embedded devices around us due to the popularity of Internet of Things (IoT…
VGF: Value-Guided Fuzzing -- Fuzzing Hardware as Hardware
Ruochen Dai, Michael Lee, Patrick Hoey +6
As the complexity of logic designs increase, new avenues for testing digital hardware becomes necessary. Fuzz Testing (fuzzing) has recently received attention as a potential candi…
LightEMU: Hardware Assisted Fuzzing of Trusted Applications
Haoqi Shan, Sravani Nissankararao, Yujia Liu +4
Trusted Execution Environments (TEEs) are deployed in many CPU designs because of the confidentiality and integrity guarantees they provide. ARM TrustZone is a TEE extensively depl…
PDNPulse: Sensing PCB Anomaly with the Intrinsic Power Delivery Network
Huifeng Zhu, Haoqi Shan, Dean Sullivan +3
The ubiquitous presence of printed circuit boards (PCBs) in modern electronic systems and embedded devices makes their integrity a top security concern. To take advantage of the ec…
