[Cbor] Re: New Videos on dCBOR-based Gordian Envelope

[Anders Rundgren <[e-mail]>]

Thanx Christopher,

It all looks interesting but it also raises a question: can you really build IETF standards on a foundation (dCBOR) which did not got WG adoption?

Although nobody have confirmed this, I believe the rationale for Numeric Reduction is the elision use case.  However, the 2.0 == 2 issue is only relevant for humans trying to match cryptographic material by manually typing in data, which only works at lab-scale.  That dCBOR rejects non-deterministic input while CDE does not(?) is rather a "quirk" in CDE (which no *serious* implementer cares about).

This empowers Data Minimization, allowing any holder of data to redact data that should be private, while still maintaining validation & integrity. The video explains more!

Its Encryption State Continuations (ESC) capability is particularly useful for air-gapped cryptographic devices, peer-to-peer services, and high-load server environments.

But if you're looking for an entry to understanding Gordian Envelope, or want to share something with other developers, this is the place to look!
