A Trusted Platform Module (TPM) is a hardware-based security module that provides a secure environment for cryptographic operations and key storage. It is a dedicated microprocessor that is designed to perform specific security-related tasks, such as generating and storing cryptographic keys, encrypting and decrypting data, and providing a secure boot process. TPMs are typically integrated into computer systems, such as laptops, desktops, and servers, to provide an additional layer of security.
