Questions about TPM utilities or TPM chip (iTPM). Ubuntu has two versions of TPM tools in the Universe repository: TPM 1.2 (tpm-tools) and TPM 2.0 (tpm2-tools).
Trusted Platform Module (TPM) is a cryptoprocessor - a dedicated microprocessor/chipset designed to securely integrate cryptographic keys, and their handling, into devices or platforms.
The TPM specification was developed by industry consortium: Trusted Computing Group (TCG), and was recognized as International Standard: ISO/IEC 11889:2009.
The Linux kernel has had driver support for TPM chips since 2.6.12. TPM 1.2 support was added in Ubuntu 7.10. TPM 2.0 tools' package is available from Ubuntu 16.04 onwards.
