What is the primary function of a TPM in an information system?
To provide memory isolation for protected system processes
To accelerate hashing operations in the CPU
To validate firmware integrity during system initialization
To maintain authentication materials and encryption elements in hardware
A Trusted Platform Module (TPM) is a specialized chip on the motherboard that provides hardware-based security functions. Its primary function is to securely store cryptographic keys, digital certificates, passwords and other authentication information. The TPM helps maintain platform integrity by ensuring the system has not been tampered with through features like secure boot and attestation. While TPMs can assist with disk encryption (often working with software like BitLocker), generate random numbers, and provide some protection against certain types of attacks, these are supporting capabilities rather than the primary function.
