Changes
* TPM is a microcontroller that stores encryption keys, passwords and digital certificates.
* When TPM technology first hit the market, it was available only in discrete form. * That is, the silicon module was separate from other system elements and communicated with them via a dedicated hardware bus.
* More recently, silicon manufacturers have begun to integrate TPM functionality into existing parts.
* Advances in on processor technologies combined with the flexibility of the TPM protocols mean that it is possible to implement the TPM as an integrated solution or in firmware.
* fTPM is a Firmware based TPM 2.0 implementation.
* Intel® PTT is an integrated solution in the Intel® Management Engine for 4th Generation Intel® Core™ processors with ultra-low TDP (Thermal Design Power) platforms and later.* '''fitlet2''', designed around Apollo Lake's SoC , features fTPM as part of Intel® Platform Trust Technology (Intel® PTT)
** Intel® PTT is a platform functionality for credential storage and key management used by Windows 8 and Windows® 10.
** Intel® PTT supports BitLocker for hard drive encryption.
