Efficient Control Flow Attestation by Speculating on Control Flow Path Representations
Liam Tyler, Adam Caulfield, Ivan De Oliveira Nunes
Control Flow Attestation (CFA) allows remote verification of run-time software integrity in embedded systems. However, CFA is limited by the storage/transmission costs of generated…
Provable Execution in Real-Time Embedded Systems
Antonio Joia Neto, Norrathep Rattanavipanon, Ivan De Oliveira Nunes
Embedded devices are increasingly ubiquitous and vital, often supporting safety-critical functions. However, due to strict cost and energy constraints, they are typically implement…
TRACES: TEE-based Runtime Auditing for Commodity Embedded Systems
Adam Caulfield, Antonio Joia Neto, Norrathep Rattanavipanon +1
Control Flow Attestation (CFA) offers a means to detect control flow hijacking attacks on remote devices, enabling verification of their runtime trustworthiness. CFA generates a tr…
SpecCFA: Enhancing Control Flow Attestation/Auditing via Application-Aware Sub-Path Speculation
Adam Caulfield, Liam Tyler, Ivan De Oliveira Nunes
At the edge of modern cyber-physical systems, Micro-Controller Units (MCUs) are responsible for safety-critical sensing/actuation. However, MCU cost constraints rule out the usual…
