TPM stands for Trusted Platform Module, which is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations and includes multiple physical security mechanisms to make it tamper-resistant. TPM technology is designed to provide hardware-based, security-related functions, and it is used to improve the security of a PC. Some of the advantages of using TPM technology are generating, storing, and limiting the use of cryptographic keys, and confirming that the operating system and firmware on a device are what theyre supposed to be, and havent been tampered with. TPMs are used by services like BitLocker drive encryption, Windows Hello, and others, to securely create and store cryptographic keys. TPMs cannot control the software that is running on a PC, but they can store pre-run time configuration parameters, and processes that need to secure secrets, such as digital signing, can be made more secure with a TPM. TPMs use cryptographic algorithms such as RSA, SHA1, and HMAC. TPMs are found on a PCs motherboard or in its processor and apply security features to store sensitive information. TPMs are required for some security features in Windows 11, such as BitLocker and Windows Hello.
