What is TPM?

Rating:

Trusted Platform Module (TPM) is a microchip that is usually installed on the motherboard of a computer. TPM communicates with the rest of the system by using a hardware bus. It provides enhanced protection for data to ensure early validation of the boot file's integrity and to guarantee that a disk has not been tampered with while the operating system was offline.

A TPM creates cryptographic keys and encrypts them so that they can be decrypted only by the TPM. This wrapping or binding process protects the key from disclosure. A TPM has a master wrapping key called the Storage Root Key (SRK). SRK is stored within the TPM itself to ensure that the private portion of the key is secure. TPM keys are decrypted only when the integrity of the system is intact.
