Re: “At the same time”:  I thought it is clear that this refers not to the timeline of some specific events, but if this may cause confusion, just rephrase it to something “also” (e.g. “End users also require greater privacy…”)

About time I weighed in on this.

Basically I am comfortable with the charter content.  It has to be a amalgam of different approaches so no one can be completely on board with it.  Really that proof will be in the output; we have to start with some goals tacked to the wall.
Agree

If I would change anything it is in the 2nd para, and that is general info which can be wordsmithed til the cows come home (as they say).  But to put my fork in it:

"At the same time"  ?? what time?  The 1st para really does not define a time.  Just drop it and start with "End users ..."

"and operators demand"  Don't make them competitative requirements.  They just are.
I will let Alex respond to these comments as he proposed the above sentence.

"Identity-enabled networks aim to enable'  They do?  Just drop the "aim to" and I think it is a stronger, yet valid, statement.
Ok will change this

For me, the rest can stand to get us off the starting block.

Good.

Thanks for your review and input.

Dear IDEAS,

Thanks to everyone who sent their comments and feedback both on the list and off the list.

This new version should address comments from:
-  Michael Menth. Michael, please let us know if this revision address some of your comments on clarity.
- Alex Clemm. Alex , please chime on the revision regarding your addition.
- Tom Herbert. Tom, Some of your suggestions are incorporated in this version.
-Tom and Alex, this version include specific working that the framework is modular. The set of areas to be covered has been reordered to put the basic identifier protocol common infrastructure first and then the new identity concept and functionalities.
- Georgios Karagiannis, Uma Chundhuri. Georgios, Uma, there is still an ongoing discussion about the framework. This version is flexible enough to accommodate the work to be done on defining the framework.
- Uma Chundhuri. Uma, the pub/sub reference should cover the inter-grids aspect if needed.

Please find the new version below:

IDEAS: “IDentity EnAbled networkS”

Proposed Charter

Network solutions based on the concept of Identifier-Locator separation are increasingly considered to support mobility and multi-homing across heterogeneous access networks. Identifier-locator separation protocols require infrastructure that allows nodes to discover the network topological location(s) of its peer(s) for packet delivery. A common infrastructure and protocol could be used by identifier/locator protocols as well as network virtualization. However, additional infrastructure and new protocol extensions are needed to address new requirements that go well beyond the traditional discovery service and mapping of identifier-to-location for packet delivery.

At the same time, end users require greater privacy for their networking information and protection from outside threats, while operators demand greater operational efficiency. Identity-enabled networks aim to enable networking applications and services that provide a high degree of privacy and control of end points over their networking data, coupled with greater inherent security than provided by today’s networks.

To this end, the working group shall:
- define a framework for the development of an identifier/locator mapping system that provides a common solution for all identifier/locator mapping protocols and network virtualization.

- in addition, introduce the concept of identity-identifier split and new mechanisms that let endpoints dynamically change identifiers. These new functionalities may, for example, facilitate anonymity through obscurity while preventing security issues that might result from abuse, ensuring that information about actual endpoints and their location is revealed only on a need-to-know basis.

Some examples of the problem space are:
- Common infrastructure and primitives: The lack of a common infrastructure is a barrier for the application of common and consistent basic networking policies. Likewise, mapping services and infrastructure that apply to identity-identifier as well as identifier-locator mappings reduces operational and deployment complexity.

- Access control: Unrestricted look up on an identifier may reveal information such as the locator to eavesdroppers. Today, there is no way to prevent the look up of an identifier with some user defined policy or finer grain rules.

- Privacy:  The use of long-lived and public identifiers may be desirable for looking up a peer, however it causes privacy issues as well. Indeed, when identifier-location pairs can be looked up without restriction, flows can be pinned by anybody to specific end systems.  The endpoint communications should be able to change their identifier while retaining their identity and associated policies. The use of temporary identifiers and access control on lookups should help discourage undesired traffic and conceal sensitive network information of end devices to eavesdroppers.

The Identity Enabled Networks (IDEAS) working group is chartered to develop a common framework that can be used by identifier-based protocols and provides services to address their requirements. We refer to the common framework providing the set of services as Generic Identity Services (GRIDS).

The working group will identify gaps and make recommendations on changes needed for interactions between the framework and identifier-enabled protocols.

Specifically, the IDEAS WG is chartered to work on these areas for the modular framework:

- Definition of primitives for interworking with identifier-location split protocols
- Identifier/locator mapping and resolution (e.g. discovery, pub/sub, multihoming, ...)
- Registration and lifecycle management of identities and their associated identifiers.
- Identity authentication and authorization (e.g. access to framework, update of information for identifiers..)
- Definition and enforcement of basic networking policies (e.g. ability to look up an identifier-locator pair, permit forwarding traffic for particular endpoints on a per-identity basis…)
- Identity and Identifier Metadata (fixed or slow changing)
- Management aspects and Data Models where appropriate.

The IDEAS WG will collaborate with other Working Groups to ensure interoperability with LISP, HIP, ILA and other relevant work. Furthermore, it will try to reuse technologies already developed when appropriate.

WG deliverables include the definition:
Generic Identity Services Framework

WG sustaining/informational documents may include:
These documents may not necessarily be published, but may be maintained in a draft form or on a collaborative Working Group wiki to support the efforts of the Working Group and help new comers:
- Problem statement
- Use cases
- Requirements
- Applications of the architecture for use cases

Milestones
March 2018 Adopt WG draft for the Generic Identity Services framework
August 2018 WGLC for the Generic Identity Services framework
December 2018 Send Generic Identity Services framework draft to the IESG
