[Ndn-interest] limit the scope of trust-anchor in trust schema

[Lixia Zhang]

Hi Nikos, yes all trust anchors have limited scope, and different trust domains have different trust anchors.

But I'm not sure how to make this a "requirement" -- NDN offers a protocol stack and framework to support security in networking, letting different parties and different applications define their own trust policies. 
As a remote, maybe inappropriate, analogy: BGP routing policy is a necessity on its own, not a requirement defined by TCP/IP.

maybe I didn't get your question right?

The trust domain concept is first defined in "Trust schemas and ICN: key to secure home IoT" by Kathleen Nichols, ACM ICN 2021.
We have a recent paper at AINTEC 2023 conference on the design of Hydra bootstrapping, which made use of trust domain (here is the pointer to the presentation of that paper:
