The commands to be sent to an application hosted in a TEE or in SE are created in a secure cloud and only needs to be forwarded to the secure component. To support this market requirement, web app needs to have a simple layer to pass command to the secure component. W3C should allow web app to access to similar service as proposed by TEE client API for the TEE or Open Mobile API for the SE presented by Herve during the Workshop.

Thanks very much for the contribution. Just so folks know, W3C is now in
procesing of setting up an official liasion relationship with

In terms of all the above good suggestions, we'd like to know more.
In my experience, a W3C Working Group maximizes its chance I think what
would be be great would be if the various solutions in this space are
sketched out in some detail before the Working Group begins.

We also have to work hard to maintain the royalty-free licensing. We
have a process for letting organizations contribute to W3C
standardization processes before the process begins via what is called
Member Submissions if a W3C member (Tyfone for example) is involved.
There is an additional Non-member contribute licensing agreement
involved we can send folks via email.
