Question

What is the main function of a TPM hardware chip?

a) Perform bulk encryption in a hardware processor
b) Control access to removable media
c) Provide authentication credentials on a hardware device
d) Generate and store cryptographic keys

Answer 1

The primary function of a TPM chip is to generate and store cryptographic keys, ensuring secure hardware-based encryption and system integrity.

Step-by-step explanation:

The main function of a TPM (Trusted Platform Module) hardware chip is to generate and store cryptographic keys. This secure cryptoprocessor is designed to carry out hardware-based encryption, ensuring that the information stored on a device is safe from unauthorized access or tampering. The TPM can also be involved in system integrity checks, password protection, and digital rights management, enhancing the overall security of a computer system.

Among its features, a TPM can:

• Generate, store, and limit the use of cryptographic keys.
• Perform attestation, which involves proving to a remote party that a system is trustworthy.
• Implement secure boot to ensure that only trusted software loads during the system startup process.

Therefore, the correct answer to the question is d) Generate and store cryptographic keys.
