What is TPM?
- A Trusted Platform Module (TPM), is a cryptographic coprocessor with capabilities of random number generation, secure generation of cryptographic keys and managed access to these keys. It includes additional capabilities such as remote attestation and sealed storage.
- TPM technical specifications are publicly available, driven by the Trusted Computing Group (TCG).
- TPM 2.0 (released October 2014) adds new functionality and fixes weaknesses of the former TPM 1.2.
dTPM (Discrete Trusted Platform Module)
- Discrete TPM is a microcontroller that stores encryption keys, passwords and digital certificates.
- fitlet2 can be ordered with an optional discrete TPM.
fTPM (Firmware Trust Platform Module)
- fTPM is a Firmware based TPM 2.0 implementation.
- Intel® PTT is an integrated solution in the Intel® Management Engine.
- fitlet2 is based on Intel Apollo Lake SoC, featuring Firmware TPM as part of Intel® Platform Trust Technology (Intel® PTT)
- The platform supports Microsoft requirements for firmware Trusted Platform Module 2.0 (fTPM). Specifically it supports credential storage and key management as used by Windows 8 and Windows® 10.
- Intel® PTT supports BitLocker for hard drive encryption.
