What is a TPM?

A TPM is a microchip designed to provide basic security-related functions, primarily involving encryption keys. The TPM is usually installed on the motherboard of a computer, and communicates with the rest of the system by using a hardware bus.

Computers that incorporate a TPM have the ability to create cryptographic keys and encrypt them so that they can be decrypted only by the TPM. This process, often called “wrapping” or “binding” a key, can help protect the key from disclosure. Each TPM has a master wrapping key, called the Storage Root Key (SRK), which is stored within the TPM itself. The private portion of a key created in a TPM is never exposed to any other component, software, process, or person.

Computers that incorporate a TPM can also create a key that has not only been wrapped, but is also tied to specific hardware or software conditions. This is called “sealing” a key. When a sealed key is first created, the TPM records a snapshot of configuration values and file hashes. A sealed key is only “unsealed” or released when those current system values match the ones in the snapshot. BitLocker uses sealed keys to detect attacks against the integrity of the Windows operating system.

With a TPM, private portions of key pairs are kept separated from the memory controlled by the operating system. Because the TPM uses its own internal firmware and logic circuits for processing instructions, it does not rely upon the operating system and is not exposed to external software vulnerabilities.

For more details on using TPM with Microsoft’s BitLocker drive encryption, please see this Microsoft webpage. Note that BitLocker is available only with Windows 7 Ultimate, Windows 8 Pro and Windows 10 Pro editions of Windows.

“A PC as it should be: clean and not heard.”

“I ordered a silent PC (ice pipe processor cooling, nofan PSU, passive graphics card, and SSD) late on a Tuesday night and it was delivered the following Tuesday. I had to contact Quiet PC to advise them I could not take a delivery on one particular day and also leave instructions about where at the delivery address the PC should be left. I had a return contact immediately, advised when the delivery would arrive, and when it was delivered - very securely packed - my instructions were typed out clearly next to the delivery address. All discs, manuals a left-over parts from the assembly thoughtfully packed-up. All those component stickers that are usually flashed across the case of PCs carefully bagged should I wish to adorn the case, which I don’t; but the PC itself is clean of labels on the outside and no bloatware on the inside. The machine is a wonder: while the PC it replaced was never noisy, this one is an acoustic black hole and utterly silent; I hadn’t realised that true silence could make using a PC so luxuriously relaxing! The PC is solidly and neatly assembled inside; and despite having no mechanical cooling, according to the monitoring software I’ve installed it runs cooler than it machine it replaced (typically 35-43C, and so far 47C max). These people are artisans of PC builders and suppliers, and to be thoroughly recommended.”
