Re: [OAUTH-WG] New Version Notification for draft-hunt-oauth-pop-architecture-00.txt

I agree with what John wrote below.  Besides, PoP is more natural to say than HoK and certainly more natural to say than HOTK.  I'd like us to stay with the term Proof-of-Possession (PoP).

Some people and specs associate holder of key with asymmetric keys.  Proof of possession is thought to be a broader category including symmetric and key agreement eg http://tools.ietf.org/html/rfc2875.

NIST defines the term PoP Protocol http://fismapedia.org/index.php?title=Term:Proof_of_Possession_Protocol

In SAML the saml:SubjectConfirmation method  is called urn:oasis:names:tc:SAML:2.0:cm:holder-of-key

In WS* the term proof of possession is more common.

So I think for this document as an overview "Proof of Possession (PoP) Architecture" is fine.

What was wrong with HOK?

Aside: Why was "the" so important in HOTK?

Prateek,
  why not just use "proof"?

draft-hunt-oauth-proof-architecture-00.txt

Is that allowed by IETF?

"key confirmed" or "key confirmation" is another term that is widely used for these use-cases

I really *like* the name "proof of possession", but I think the acronym PoP is going to be confused with POP.  HOTK has the advantage of not being a homonym for aything else.  What about "Possession Proof"?

Abstract:
  The OAuth 2.0 bearer token specification, as defined in RFC 6750,
  allows any party in possession of a bearer token (a "bearer") to get
  access to the associated resources (without demonstrating possession
  of a cryptographic key).  To prevent misuse, bearer tokens must to be
  protected from disclosure in transit and at rest.

  Some scenarios demand additional security protection whereby a client
  needs to demonstrate possession of cryptographic keying material when
  accessing a protected resource.  This document motivates the
  development of the OAuth 2.0 proof-of-possession security mechanism.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org/>.
