What function is performed by the Trusted Platform Module (TPM)?

1. Encrypt user credentials

2. Create a hash of system components

3. Store all user passwords

4. Manage user access control

The correct answer is: Create a hash of system components

The Trusted Platform Module (TPM) is primarily designed to enhance computer security through hardware-based protection. One of its key functions is to create a hash of system components. This hashing process generates a fixed-size string of characters that uniquely represents the state of software or firmware at a specific point in time. By doing this, the TPM can help verify the integrity of the system during boot-up and ensure that it has not been tampered with. When a system starts, the TPM can measure and store hashes of all critical software components in a secure manner. During subsequent boots, the platform can compare the current hashes with the stored values to ensure everything is as expected. If there are any discrepancies, the system can identify potential unauthorized changes that could indicate security breaches or malware infections. Other functions often associated with the TPM include secure generation and storage of cryptographic keys, but the primary focus on creating and managing hashes helps ensure the integrity of the platform's boot process and operational environment.
