RE: [W3C Web Crypto WG] Rechartering discussion - Gemalto contribution

Brad,

I agree with you that access control and privacy protection are very important, and it is inappropriate to proceed without them. We have been considering these issues, as shown in our paper in the workshop last year.

http://www.w3.org/2012/webcrypto/webcrypto-next-workshop/papers/Gemalto_position_paper.html


Together we can work out a solution that respects the web security and threat model and may enhance it.

Thanks,
Karen

I would like to see details of how this kind of API would or could interact with the Same-Origin model of web security, specifically:

1.       Privacy and tracking.  How does the presence of specific crypto elements and discoverable keys which are not Origin-scoped not create privacy violations?
2. Origin security.  How are risks around identification of or impersonation of the server-side of a transaction, and potential abuse of a globally-scope key mitigated by  this kind of API design?

Without a clear discussion of how this API fits into the existing Web security and threat model, I think it is inappropriate to proceed.  We can't just throw away the fundamental security model that billions of users and deployed applications depend on, and I see no evidence (at least in these few slides) that such issues have been considered by this proposal.

Dear all,

Web Crypto WG charter [1] will end by the end of March. We need to prepare the next charter of Web Crypto.

As a reminder, the conversation has started on this page :   https://www.w3.org/Security/wiki/IG/webcryptonext_draft_charter

Feel free to add you ideas and suggestions on the wiki and/or expose your opinion and question on the public-webcrypto@w3.org<mailto:public-webcrypto@w3.org> or public-webcrypto-comment@w3.org<mailto:public-webcrypto-comment@w3.org> (for non W3C Web Crypto WG members).

Regards,
Virginie
