It’s a 1.2 Trusted Platform Module from Infineon, buried in the ACPI tables of late-2000s laptops. For its time, it was cutting-edge — hardware root of trust for BitLocker and measured boot. Today, it’s a legacy component: too slow for modern security demands, vulnerable to ROCA if unpatched, and excluded from Windows 11 entirely.

So, ACPI IFX0102 = chip attached via the LPC bus and exposed through ACPI firmware. 2. What It Actually Is: TPM 1.2 The IFX0102 is a TPM (Trusted Platform Module) 1.2 device, typically the Infineon SLB 9635 TT 1.2 or similar. acpi ifx0102
