Subject: Document Action: 'Sakai-Kasahara Key Establishment (SAKKE)' to Informational RFC (draft-groves-sakke-03.txt)

The IESG has approved the following document:
- 'Sakai-Kasahara Key Establishment (SAKKE)'
  (draft-groves-sakke-03.txt) as an Informational RFC

This document has been reviewed in the IETF but is not the product of an
IETF Working Group.

Technical Summary

   This document defines an efficient use of Identifier-Based Encryption
   (IBE) based on bilinear pairings.  The Sakai-Kasahara IBE
   cryptosystem [S-K] is described for establishment of a shared secret
   value.  

Working Group Summary

   This is not the product of any working group.  This document provides an
   alternative to the IBE options available in [RFC5091], providing an
   efficient primitive and an additional family of curves. 
 
   This document is restricted to a particular family of curves compatible
   with a simple and efficient method of calculating the pairing on which
   the Sakai-Kasahara IBE cryptosystem is based.

   This submission is part of a family of specifications specifying a new
   mikey mode for use in 3GPP.  Adoption by 3GPP is not assured.

Document Quality

   There are no known commercial implementations, but the
   Sakai-Kasahara IBE cryptosystem is widely known in cryptographic
   communities and considered to be secure.  If the corresponding mikey
   mode is adopted by 3GPP, a number of implementations are expected.

Personnel

   Tim Polk is the Document Shepherd.
   Sean Turner is the Responsible AD.
