TPM

The TPM is often built into a system to provide hardware-based security. It is a combination of hardware and software to protect credentials when they are in an unencrypted form. TPM is based on a trusted execution environment (hardware root of trust) that provides secure storage of credentials and protected execution of cryptographic operations. It is isolated from the main CPU and implemented either as a discrete chip, a security coprocessor, or in firmware:

• The microprocessor scans the firmware and validates the key. If the key is valid, then the processor begins executing the firmware, but if not, the processor halts.
• The TPM is used to store platform measurements that help ensure that the platform remains trustworthy. It contains ...
