Reorganize the availability section

I'd like to reorganize the availability section, which is titled TPM is implemented by several vendors: into sections on the TPM itself, platforms, software support, virtualization.

Is that OK? — Preceding unsigned comment added by Kgold1 (talk • contribs) 17:55, 2021 June 17 (UTC)

Restriction law section

The restriction law section states that Chinese and Russian laws restrict TPM access and then link to an article that speculates the reason that Windows 11 has optional flags to remove the TPM requirement is due to these laws.

However, the following press release shows that China and Russia both approved of TPM 2.0 -- https://trustedcomputinggroup.org/trusted-computing-group-tpm-2-0-library-specification-approved-isoiec-international-standard-date-published-june-29-2015/

I can also confirm that desktops that have been purchased in China have TPMs in them. — Preceding unsigned comment added by 59.148.176.172 (talk) 08:04, 2021 July 21 (UTC)

Needs reference for edit on Chinese algorithms.

A recent edit says (in the past). This needs a citation. — Preceding unsigned comment added by Kgold1 (talk • contribs) 21:11, 2021 August 13 (UTC)

Discrete TPMs in Cars

For example, the TPM for the brake controller in a car is protected from hacking by sophisticated methods.

I can't dispute that the linked source does day that, but this doesn't make much sense as an example to me. TPMs can't do general purpose computing, right? They can do a very limited set of cryptographic operations. Why would a brake controller in a car need to do cryptographic stuff? Maybe to secure a communication channel to the breaks? That feels like a weird thing to secure given that if you can attack the break controller, you can probably attack the breaks as well. Jon.Penn (talk) 20:36, 21 February 2025 (UTC)[reply]

~~The TPM for a car is almost certainly the Tire Pressure Monitoring System (TPMS), it probably tells the breaks if there's a blown tire.~~ (Edit, I was wrong here.) Ikmxx (talk) 03:07, 26 September 2025 (UTC)[reply]

No, it is a Trusted Platform Module (TPM) for the braking system, not TPMS. The ability to remotely engage the brakes on a car - or disable them - for nefarious purposes, is a real safety threat - just as also if the accelerator were compromised and the car ignored attempts to slow down. In years past there were an assortment of demonstrations by 'white hat' hackers that revealed these vulnerabilities, which required a rethinking of how the communication channels were handled. Encryption of the communications was necessary. This is detailed in the link the previous user included. cheers. anastrophe, an editor he is. 04:25, 26 September 2025 (UTC)[reply]

Thanks! That makes more sense than what I was thinking. Ikmxx (talk) 07:04, 27 September 2025 (UTC)[reply]

Currently ...

"Currently, a TPM is provided by nearly all PC and notebook manufacturers in their products." When is currently? Now? Since when? Darsie42 (talk) 13:38, 21 August 2025 (UTC)[reply]

I've swapped in place the {{As of|2025}} template to remove whatever ambiguity may be perceived. cheers. anastrophe, an editor he is. cheers. anastrophe, an editor he is. 22:08, 28 September 2025 (UTC)[reply]
