Fault-Injection Detection Circuits - Design, Calibration, Validation and Tuning

Explore the tunable replica circuit (TRC), a fault-injection detection mechanism integrated into Intel® Converged Security and Management Engine (Intel® CSME) for 12th Gen Intel® Core™ Processors. This 35-minute Black Hat conference talk delves into Intel's pioneering approach to active fault-injection attack detection in high-volume products like CPUs and chipsets. Learn how the TRC explicitly detects timing failures, the primary goal of fault-injection attacks, and understand Intel's strategy for enhancing security in client security engines. Gain insights into the design, calibration, validation, and tuning processes of this innovative fault-injection detection circuit.
