Web & TV group,

Earlier in the week we discussed requirements for unique identifiers for devices in the context of premium video services.

Within the WebCrypto group we discussed the idea of pre-provisioned symmetric cryptographic keys and the association of unique identifiers with these keys. This is based on a proposal from Netflix to address our requirements for secure binding of application protocol to devices, particularly on TVs, BluRay Players etc.

The latest proposal for this is available here: http://lists.w3.org/Archives/Public/public-webcrypto/2012Nov/0014.html

One question in the WebCrypto WG discussion was whether there were others who shared this requirement ? Since we discussed this in the Web & TV group I am posing the question to this list. Note that the possibility for UAs to support pre-provisioned keys is agreed in the WebCrypto group. The issue at hand is whether there should be a standard way to expose a unique identifier associated with such keys.

If you have comments or questions on the proposal please send them to the WebCrypto list, particularly if the proposal does or does not meet your requirements (public-webcrypto@w3.org<mailto:public-webcrypto@w3.org> if you are a member or public-webcrypto-comments@w3.org<mailto:public-webcrypto-comments@w3.org> if not). This issue will be decided at the next WebCrypto call on 11/19.

Best regards,
