Intel introduces physical fault injection protection

Intel announced fault injection protection in its 12th generation Intel Core processors on Thursday.

TRCs are designed to detect non-invasive physical glitch attacks and electromagnetic fault injections.

TRC detects dynamic variations in circuits using hardware-based sensors and can be fine-tuned to detect timing violations caused by an attack.
Attackers can use fault injection to execute malicious instructions and potentially leak data via clock pin, electromagnetic, and voltage glitches.

A launching flip-flop (FF), a tunable delay chain, and a capture FF comprise the TRC.

The tech behemoth claims to have developed a feedback-based calibration flow that will help eliminate false-positives and false-negatives.
