Windows 11: TPMs and Digital Sovereignty

This article is an opinion held by a subset of members about the potential plan from Microsoft about their enforcement of a TPM to use Windows 11 and various features. This article will not go into great detail about all the good and bad of a TPM; there will be links at the end for you to continue your research, but it will go into the issues we see with enforcement. If you’re unfamiliar with what a TPM is or its general function we recommend taking a look at these links: What is a TPM?; TPM and Attestation.

As you may or may not have already noticed, many people are wondering about Microsoft’s new mandatory TPM 2.0 hardware requirement for Windows 11. If you look around the press releases, shallow technical documentation, and the myriad of buzzwords like “security,” “device health,” “firmware vulnerabilities,” and “malware,” you still haven’t received a straightforward answer as to why exactly you need this tech.

Part of system requirements from Microsoft

Many of you reading this article may have machines around the house or office you built from silicon that isn’t even seven years old. These still play today’s latest games without hiccup or issue, and unless you let your Grandma or 6-year old nephew on the machine recently, you likely don’t have malware either.

So, why do I suddenly need a TPM 2.0 device on my machine, then you ask? Well, the answer is quite simple. It’s not about you; it’s about them.

You see, the PC (emphasis on personal here) is in a way the last bastion of digital freedom you have, and that door is slowly closing. You need to only look at highly locked and controlled systems like consoles and phones to see the disparity.

Political affiliations aside, one can take the Wikileaks app removal from both the Apple store and Google play store as an excellent example of what the world looks like when your device controls you, instead of you controlling the device.

How does a TPM on my PC advance this agenda?

Twenty years ago, Microsoft set forth a goal of “trusted” computing called Palladium. While this technical goal has slowly but surely crept into Windows over the years, it has laid chiefly dormant because of critical missing infrastructure. This being that until recently, quite a large majority of consumer machines did not have a TPM, which you’ll learn later is a critical component to making Palladium work. And while we won’t deny that Bitlocker is excellent for if your device ever gets stolen, we will remind you that Microsoft always sold this tyranny to look great on the surface (no pun intended here).

When Palladium debuted, it was shot out of orbit by proponents of free and open software and back into hiding it went.

Comment about vendor withdrawal problem

So why is the TPM useful? The TPM (along with suitable firmware) is critical to measuring the state of your device - the boot state, in particular, to attest to a remote party that your machine is in a non-rooted state. It’s very similar to the Widevine L1 on Android devices; a third-party can then choose whether or not to serve you content. Everything will suddenly revolve around this “trust factor” of your PC. Imagine you want to watch your favorite show on Netflix in 4k, but your hardware trust factor is low? Too bad you’ll have to settle for the 720p stream. Untrusted devices could be watching in an instance of Linux KVM, and we can’t risk your pirating tools running in the background!

You might think that “It’s okay, though! I can emulate a TPM with KVM; the software already exists!” The unfortunate truth is that it’s not that simple. TPMs have unique keys burned in at manufacture time called Endorsement Keys, and these are unique per TPM. These keys are then cryptographically tied to the vendor who issued them, and as such, not only does a TPM uniquely identify your machine anywhere in the world, but content distributors can pick and choose what TPM vendors they want to trust. Sound familiar to you? It’s called Digital Rights Management, otherwise known as DRM.

Let’s not forget, Intel initially shipped the Pentium III with a built-in serial number unique per chip. Much the same initial fate as Palladium, it was also shot down by privacy groups, and the feature was subject to removal.

A common misunderstanding

There seems to be a lot misconceptions floating around in social media. In this section we’ll highlight one of them:

“I can patch the ISO or download one that removes the requirement.”

You can, sure. Windows and a majority of its components will function fine, similar to if you root your phone. Remember the part earlier, though, about 4k video content? That won’t be available to you (as an example). Whether it be a game or a movie, a vendor of consumable media decides what users they trust with their content. Unfortunately, without a TPM, you aren’t cutting it.

You’ve probably noticed that the marketing for this requirement is vague and confusing, and that’s intentional. It doesn’t do much for you, the consumer. However, it does set the stage for the future where Microsoft begins shipping their TPM on your processor. Enter Microsoft’s Pluton. The same technology is present in the Xbox. It would be an absolute dream come true for companies and vendors with special interests to completely own and control your PC to the same degree as a phone or the Xbox.

While the writers of this article will not deny that device attestation can bring excellent security for the standard consumers of the world, we cannot ignore that it opens the door to the restriction of user privacy and freedoms. It also paves the way to have the PC locked into a nice controllable cube for all the citizens to use.

You can see the wood for the trees here. When a company tells you that you need something, and it’s “for your own good,” and hey, they’re just on a humanitarian aid mission to save you from yourself, one should be highly skeptical. Microsoft is pushing this hard; we can even see them citing entirely dubious statistics. We took this one from The Verge:

“Microsoft has been warning for months that firmware attacks are on the rise. “Our Security Signals report found that 83 percent of businesses experienced a firmware attack, and only 29 percent are allocating resources to protect this critical layer,” says Weston.”

If you read into this link, you will find it cites information from Microsoft themselves, called “Security Signals,” and by the time you’re done reading it, you forgot how you got there in the first place. Not only is this statistic not factual, but successful firmware attacks are incredibly rare. Did we mention that a TPM isn’t going to protect you from UEFI malware that was planted on the device by a rogue agent at manufacture time? What about dynamic firmware attacks? Did you know that technologies such as Intel Boot Guard that have existed for the better part of a decade defend well against such attacks that might seek to overwrite flash memory?

Takeaway

We are here to remind you that the TPM requirement of Windows 11 furthers the agenda to protect the PC against you, its owner. It is one step closer to the lockdown of the PC. As Microsoft won the secure boot battle a decade ago, which is where Microsoft became the sole owner of the Secure Boot keys, this move also further tightens the screws on the liberties the PC gives us. While it won’t be evident immediately upon the launch of Windows 11, the pieces are moving together at a much faster pace.

We ask you to do your research in an age of increased restriction of personal freedom, censorship, and endless media propaganda. We strongly encourage you to research Microsoft’s future Pluton chip.
