(RP) Intel présente les premières protections contre certaines menaces physiques

Intel improves software reliability by building silicon enhancements realized through logic inside the processor. Aujourd'hui, the company described a new technique to complement existing software mitigations for fault injection attacks. Tunable Replica Circuit (TRC) – Fault Injection Protection uses hardware-based sensors to explicitly detect circuit-based timing failures that occur as the result of an attack. TRC is first delivered in the 12th Gen Intel Core processor family. It adds fault injection detection technology to the Intel Converged Security and Management Engine (Intel CSME), where it is designed to detect non-invasive physical glitch attacks on the pins supplying clock and voltage. TRC is also designed to detect electromagnetic fault injections.

"Software protections have hardened with virtualization, stack canaries and code authentication before execution," said Daniel Nemiroff, senior principal engineer at Intel. "This has driven malicious actors to turn their attention to physically attacking computing platforms. A favorite tool of these attackers is fault injection attacks via glitching voltage, clock pins and electromagnetic radiation that cause circuit timing faults and may allow execution of malicious instructions and potential exfiltration of secrets."
