Plagiarism?

Large parts of this article apparently consist of unattributed, near-verbatim excerpts from a SANE2004 paper by Weis, Lucks, and Bogk, TCG 1.2 - fair play with the 'Fritz' chip?. Regardless of whether one believes that general political/ethical concerns about Trusted Computing belong on a Thinkpad-specific site, wholesale copying of unidentified, and presumably copyrighted, material is not cool, and could get the whole project in trouble.

I would suggest that the non-original parts of this article be removed and replaced by an external link to the above-mentioned paper; any particularly crucial short excerpts (as permitted by "fair use") should be clearly identified as such. The specific information about how the TCG specifications are implemented on various Thinkpad models can stay, of course.

The Source is under Creative Commons, isn't it?

Hello Andrzej,

yes, you are right, another version of this text on a website of the presentation of the annual chaos computer club is one of my sources, but I think, that one is under creative commons license by-nc-sa 2.0 de. And are the presentations of the chaos computer congress not also free unless the speakers don't want it??????

This license allows to copy, distribute, display, perform or modify the text as long as it is published under exactly the same creative commons license and licensees may not use the work for commercial purposes - unless they get the licensor's permission.

My problem was, I had a lot more sources in a different language than english and my first drafts were way to long!

It didn't worked to keep it that short but detailed, as Ruediger and Adreas wrote it.

But if you think, after my explanation the actual version is still problematic, I will delete it of course!

If the original authors have explicitly published the text under a suitably permissive CC license, there should be no legal problem in using it in a ThinkWiki article. Even in that case, however, the source needs to be clearly identified, and there should be a link to the complete original article.

Okay Andrzej, I will work on that and tell all of you about it in the coming days, if I have enough time for it.

Unless that, feel free to take out the critical passages of the article or modify it, if you have the time and if you want to do it.

But there is a problem: I slightly changed the text, put two sentence together to one etc. How can I now cite the source?

No problem; just say that your ThinkWiki article is based on the Weis et al. paper, and give a reference. The parts of their text that you include don't have to be verbatim copies; indeed, the whole point is that you are creating a derived work (e.g., by bringing in material from other sources), which they supposedly explicitly allow in the CC license. To be on the safe side, you should probably also include a link to a web page documenting that the original text is indeed freely licensed, or say that you have personally obtained permission from the authors.

Agreed. There should be a general statement in the article about the source the article is derived from, or rather sources - i seem to have used different sources of information for some of my edits. ;-) I'll add mine on next edit.

Thanks for your work, i like it

Hello Wyrfel,

thank you very much for editing and restructering of that article.

I think, I know know what you and Andrzej want and I will try in he next days, to change the article in that way, okay?

P.S.: I don't know, why I loose my logged-in status from time to time, perhaps my connection. I am sorry, that there are IP-Adresses instead of my unsername "pitsche", I hope, no one gets confused, which edit is by me and which one by someone else :-o

Sorry.

About your login status: ThinkWiki doesn't cache logins. This means everytime your connection breaks or your browser closes you will have to login again. But don't worry, we can figure out what's from you and if not - it's a Wiki. ;-) I'm doing a lot of edits without being logged in as well.

No exact TCG specifications needed

Hello again!

I am against writing about the specific specifications, because it will make the article longer and everybody, who is really interested in the specifications has several possibilities to get it for free in the WWW or from Cryptolabs.org or from the CCC.

I think the TCG specifications should appear there somewhere. At least at current state of my knowledge about the subject i'd think that having them there is helpful for the user to understand what ESS 1 and 2 are capable of. Of course we shouldn't post the whole specs, but some really compressed summary, similar to the 'feature-list' in "TC - Trusted Computing". Pitsche, if you could point me to them i could do it. Also, a link to the original TCPA specs would be good. The links themselves should be added to the Links section.

That's it so far...i like the way we work on this.

Wyrfel.

One more thing...

I think the TCPA implementation in current ThinkPads is pretty harmless. At least at it's current software state. You just don't use it (respectively don't install the supporting software layer) and it never gets active. One interesting aspect of finding out what the chip is capable of is if it could be forced to be used by later software upgrades or not.
