North Americaâs east coast is braced for record snowfall a year after the polar vortex. Just what does such intense cold do to the human body?
A Trusted Platform Module (TPM) is a specialized chip on an endpoint device that stores RSA encryption keys specific to the host system for hardware authentication. Each TPM chip contains an RSA key pair called the Endorsement Key (EK).
A TPM must also have an Endorsement Key (EK), which is permanent once set for that TPM. Other keys are derived from or signed by the EK. Every time the computer starts, certain measurements are made and stored in the TPM's platform control registers (PCRs). PCRs are discussed in more detail later in this chapter.
