Intel® Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel® processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. It enables an environment where applications can run within their own space, protected from all other software on the system.

TPM (Trusted Platform Module) is a component that provides hardware level security upon system boot-up via stored security keys, passwords, encryption and hash functions.
