Hi Everyone,
I do agree with Siva, enabling an access to secure element in general will allow to address many use cases and can multiply implementations.

Kind regards,

Bruno

Hopefully we standardize a "pipe" and not be prescriptive on specific ID auth/management methods (e.g. EMV organizations, FIDO, PKCS, Derived credential etc). So all such relevant ID auth methods can co-exist since it is very difficult envision convergence of between these methods.

So let's figure out how!

There we have a truly Herculean task!

FIDO "cheated" and took the route which I have advocated years before FIDO started [1], namely building a standardized web-enabled security-element architecture which can be implemented as external tokens, pure software or be a part of a TEE.
A guesstimate is that the specification-set would "only" require 300-400 pages to match existing (non-webby) tokens.

However, "there is more than meets the eye" [2], at least in my take on the matter we are talking about major changes in both browsers and OSes.

Cheers,
Anders

Hadi is right. Officially it is expected that visa/mc will put a ecommerce pricing table together that uses tokenization (like Apple Pay) that has has lower rates than traditional CNP ecommerce. Will it approach CP rates depends on ID Validation and Assurance used.

Apple Pay tokens have NIST Level 4 ID Assurance because of the use of hardware secure element. I think iPhone 6 has a SmartMX smart card controller. So CP rates is quite likely for Apple Pay based ecommerce.

Rumor has it that Apple Pay might be getting CP (Card Present) rates for
remote purchases made using iPhone 6/+.

Hi Virginie,

During the 20Y+ we have bought stuff on the web and paid with credit
cards,
the method haven't changed.  That is, in spite of a billion s.c. EMV-cards
in circulation, on the web we are currently stuck with highly inconvenient
and (any number of times proved) unsecure CNP (Card Not Present) schemes..

To me it looks like a task for your particular sector coming up with a
proposal on how to address this pretty obvious use case.

Apple have advanced the state of on-line payments by a mile in iPhone 6,
but AFAIK it doesn't include the web.

Sincerely,
Anders Rundgren

Dear all,

A short status of where we are in the Web Crypto Next Workshop follow
up.

-As announced [1], a wiki has been set up to receive your ideas about
the re-chartering of Web Crypto WG, taking into account the findings of
the Web Crypto Next Workshop.

-The workshop report will soon made available by Harry Halpin probably
next week, it will be circulated on this mailing list for review during
one week.

-During  W3C TPAC meeting scheduled on 26-31 Oct [2] , there will be
some actions to socialize the workshop findings with W3C members (during
security related WG, during the AC representatives meeting, and during
Wednesday Break-Out sessions)

-Still during the TPAC week, Wendy, W3C security domain leader has
organized a conversation with Web App Sec and Web Crypto chairs to see
how we could re-charter both groups in synchronization, taking into
account workshop findings.

If you need some help to contribute, give your opinion, better
understand direction, do not hesitate to ask question to Wendy, Harry,
or myself !

Regards,

Virginie Galindo
