Dear Crypto Panel members,

CFRG chairs = received a request to review this document (maybe even 2 reviews), ideally by March 4. (If you miss the deadline, a review that is completed later is still useful.) Any takers?

In= particular, the review should concentrate on the following aspects of the proposal:

EDHOC (https://datatracker.ietf.org/do= c/draft-selander-ace-cose-ecdhe-11) is being proposed as a new AKE to meet the need of constrained/IoT environments (such as those considered by the ACE WG). Formal analysis on -08 was conducted by [1] [2]. A review by the Crypto Review Panel would be helpful to evaluate the security properties (mutual authentication, PFS, and identity protection) claimed by the draft: 

** Top-line: does EDHOC provide the security prop=
erties it asserts?  How do we reason about/approach answering  that questio=
n?
** Is this draft complete -- what would you like to see that isn't writ=
ten?
** What areas of the draft or features of the protocol require further anal=
ysis or polish?  Are the prerequisite/assumptions clear enough?
** Are the choice of ciphersuites acceptable?=20
** Does the formal analysis in [1] appear credible?
** Does -11 appear to have addressed the concerned outlined by [1] in -08? =
(The authors of [1] are working on an update of the analysis on -11)

A related key question being discussed is "ignoring whether the securi=
ty properties of EDHOC are valid, can the 'lightweight property of EDHO=
C' be realized with another protocol"

So I don't see what we stand to gain by a further IPR discussion, especially since such discussions are rarely conclusive. I don't think there's anyone claiming that the IPR situation for wideblock OCB is different than the baseline OCB.
