Talk:Embedded Security Subsystem

Q: Good or Bad?

Someone said: This Security Chip is a hardware trojan. True or false?

hmmm. depends. but the fear is big, that it is trojan...

Hello,

I would say it depends, how TCPA/'Fritz'-Chip is used. But the fear of the critics and (cyber) civil rights people are, that the industry wants to control the use of digital media like MP3, DVD, etc. to prevent copying - even if you own it.

There is also a fear, that there are hidden channels in this black box type of hardware, because hidden channels where found in so many black box type of hardware for years now. What is transmitted over these hidden channels?

The recent modifications by the TCG because of the critic and the resulting pressure are a good beginning. We, the consumers and users, have to go an with our demands, with our critic and we have to look carefully, what TCG and the others are doing here.

Why? Because it will affect all of us sooner or later in using our MP3- or DVD-Players or e.g. -Software on our computers etc. And you can think also about your mobile cellular phones, digital cameras and so on. Digital content, digital media is more and more widespread.

And this is where Digital Rights Management (DRM) comes into the game. DRM is feared to be a trade barrier for a free market, a barrier to future historians, etc.

Trusted Computing is not bad by meaning, but it is bad (or 'lousy'?), how the industry is implementing it. They could do better, right?

ESS page may have errors...

Hi, The ESS 1.0 section claims that its based on TCG 1.1 specs, but I cannot find anything to support that. The ESS 2.0 systems I have all have v1.1 TPMs in them, but I don't have an ESS 1.0 system. As far as I know, the ESS 1.0 does not implement any TCG specification.

Also, the ESS 2.0 does not provide a TCG 1.2 TPM. No currently shipping IBM platforms contain 1.2 TPMs. I thought I'd mention this stuff somewhere before just changing the wiki with no discussion.

Thanks

Thanks. You could have just changed it and leave a note with pointers to your sources. I also wondered about the fact that IBM says nothing about TCG in ESS 1.0, but i didn't find any more detailed information. Did you? And if so, where?

Yeah, I am seeing less and less on ESS 1.0 on www.ibm.com, which is my source for this stuff. If I come across anything concrete, I'll post it.

X60, X60s and T60 with TCG 1.2-compliant Atmel chip

Lenovo's "Personal Systems Reference" on Thinkpad Notebooks version 301, January 2006 states that Thinkpads X60, X60 and T60 are equipped with a "Trusted Platform Module / Atmel chip / TCG 1.2-compliant".

Could this be the Atmel AT97SC3203? Can anyone confirm this?

What about linux support for this chip?
