The Trusted Platform Module (TPM), developed by the Trusted Computing Group (TCG), is a compulsory security element in any pc operating Home windows 11. It shops delicate data akin 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 gadget, they will 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 sort of assault with out the necessity to make adjustments to gadget encryption software program akin to BitLocker. TPM Guard is a mixture of {hardware} and firmware that creates an authenticated and encrypted tunnel between the TPM and the CPU to guard the communication between them, stated Ian Pratt, HP’s vp of security 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.
