Hi Virginie,

If you pay in a shop using your "Carte Bancaire" you put the card in a terminal
provided by a certified vendor of trusted payment terminals, right?

That is, the card is never directly exposed to potentially malicious merchant code.

Now if you rather go to the Web, you'll find that the entire concept "Trusted Web Code" [1] is missing
which makes all efforts merging generic security hardware [2,3] with browsers doomed to fail.

Sincerely,
Anders Rundgren

1] Trusted UI + Trusted Software
2] GP TEE, SIM, PIV, TPM, etc.
3] FIDO/U2F is special purpose and limited by SOP so it is outside of this discussion.

The group is currently discussing the gemalto proposal for certificate management, integrating the usage of hardware token for cryptographic operation, with no consensus on that matter. if you are willing to support one of those topic, please speak on the public-webcrypto mailing list [1].

That technology is backed by a strong strategy by Microsoft and Google. I suggest we let FIDO Alliance decide when they are ready to input to W3C their contribution in terms which are compliant with W3C IP policy.

It may happen that the Web Payment IG ends with that kind of consensual requirements. I can only encourage people interested in payment to join the IG or at least monitor their deliverables [2].

The way to go on the discussion could be either to create a W3C community group, it is very light and easy to manage and join. But there is another possibility : from what I see, GlobalPlatform is willing to host the discussion in ordre to allow all players to design a flexible technical solution, allowing browser to integrate in a flexible way any services using hardware token. GP will soon open a public working group, with an IP policy compliant with W3C one, to discuss that.
