A Trusted Platform Module (TPM) is a specialized hardware component designed to enhance computer security. It provides a secure environment for storing cryptographic keys, passwords, and digital certificates, ensuring that sensitive data remains protected from unauthorized access. By integrating with the computer's operating system, a TPM can help verify the integrity of the system during boot-up and prevent tampering. TPMs are commonly used in various devices, including laptops and servers, to support features like full disk encryption and secure authentication. They play a crucial role in establishing a trusted computing environment, making it harder for malware and other threats to compromise system security.
