The Trusted Platform Module (TPM), developed by the Trusted Computing Group (TCG), is a compulsory safety part in any pc operating Home windows 11. It shops delicate info comparable to encryption keys in a separate, safe chip, passing it to the CPU as required.
Nonetheless, there’s an issue. If an attacker can get bodily entry to the system, they’ll use {hardware} costing lower than $20, operating available software program, to seize these encryption keys as they’re despatched to the CPU, permitting knowledge on the system to be readily decrypted by the attacker and stolen.
At its Think about occasion this week, HP introduced a product that it says prevents this type of assault with out the necessity to make adjustments to system encryption software program comparable to BitLocker. TPM Guard is a mix of {hardware} and firmware that creates an authenticated and encrypted tunnel between the TPM and the CPU to guard the communication between them, mentioned Ian Pratt, HP’s vp of safety and business programs. The TPM is cryptographically sure to the host processor so if the chip is faraway from the system, the TPM will stop to operate.
