Which of the following, BEST explains the function of TPM?

A Trusted Platform Module (TPM) is a secure cryptoprocessor that provides hardware-based security features, including the generation, storage, and protection of cryptographic keys in a tamper-resistant environment. This capability underpins features like secure boot, disk encryption (e.g., BitLocker), and strong authentication, making it resistant to software-based attacks.

While TPM does store security measurements for platform integrity, its primary and overarching function is broader hardware-based security using unique keys, and 'ensuring platform confidentiality' is a result rather than the best explanation of its core function.

TPM is a security chip and does not primarily 'improve management of the OS installation'; rather, it secures the OS boot process and data after installation.

TPM enables and supports encryption algorithms for hard drives by securely storing keys, but its core function is to 'provide' secure key management and a trusted environment, not solely to 'implement encryption algorithms' itself.
