==What is TPM?==
A Trusted Platform Module (TPM), is a cryptographic coprocessor including capabilities for random number generation, secure generation of cryptographic keys and limitation of their use. It also includes capabilities such as remote attestation and sealed storage.
TPM's technical specification is 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.
