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.
