Add EAD_3 field? #2

Closed geonnave closed 6 months ago

geonnave commented 11 months ago

After receiving message_3, V may want to check that CRED_U is bound to the voucher received from W (see #1). In this case, V would need to (1) have the voucher saved on state, and (2) it would have to dispatch a "check CRED_U against Voucher" action.

Right now, on the implementation side, dispatching any EAD-related action is done via detecting the presence of an EAD field (since the core EDHOC implementation must be agnostic of EAD items).

Thus, it may make sense to add an EAD_3 field to enable such a dispatch.

As discussed in the design team meeting, the next step is to think of additional scenarios where this might be needed (if any).
