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. TPMs are commonly used in devices like laptops and servers to support features such as secure boot and disk encryption. TPMs work by generating and managing cryptographic keys that can be used for various security functions. They help verify the integrity of the system during startup and can also facilitate secure transactions in applications like Microsoft Windows and BitLocker. This technology plays a crucial role in maintaining trust in computing environments.
