* A Trusted Platform Module (TPM), is a cryptographic coprocessor including with capabilities for of random number generation, secure generation of cryptographic keys and limitation of their usemanaged access to these keys. It also includes additional capabilities such as remote attestation and sealed storage. * TPM's technical specification is specifications are publicly available, driven by the Trusted Computing Group (TCG). The latest version * TPM 2.0 (released October 2014), is a major redesign of the specification which adds new functionality and fixes weaknesses of the former TPM 1.2.

* Discrete TPM is a microcontroller that stores encryption keys, passwords and digital certificates. * When TPM technology first hit the market, it was available only in fitlet2 can be ordered with an optional discrete form. <br>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.

* 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 an integrated solution in the Intel® Management Engine for 4th Generation Intel® Core™ processors with ultra-low TDP (Thermal Design Power) platforms and later.** The platform also supports all Microsoft requirements for firmware Trusted Platform Module 2.0(fTPM).** Intel® PTT is a platform functionality for <br>Specifically it supports credential storage and key management as used by Windows 8 and Windows® 10. ** Also possible in Linux to encrypt partitions using LUKS (Linux Unified Key Setup). <br> See [[Linux: Full Disk Encryption]]
