Microsoft currently uses Infineon Technologies OPTIGA Trusted Platform Modules (TPMs) in its newest personal computing devices, including the Surface Pro 4 tablet and the Surface Book. The dedicated security chips store sensitive data, including keys, certificates, and passwords and keeps them separated from the main processor, which further secures the system from unauthorized access, manipulation, and data theft. For example, the Microsoft BitLocker Drive Encryption application’s key and password are stored in the TPM.
Microsoft’s personal computing devices rely on the OPTIGA TPM SLB 9665, which is the first certified security controller based on TPM 2.0. This standard was defined by the Trusted Computing Group (TCG).
