Hi cfrg folks, We have recently updated three I-Ds related ID-based authenticated key exchange.. draft-kato-fsu-key-exchange-01.txt draft-kato-optimal-ate-pairings-01.txt draft-kasamatsu-bncurves-02.txt The I-Ds specifies key exchange protocols, pairing algorithm, and pairing friendly curves respectively. The main change from -00 to -01 of FSU is added an "Our Motivation" section that came from a hannes's question on FSU, Thank you for Hannes Tschofenig and Tadanori Teruya by the on/off-list comments and questions. We would appreciate your any technical/editorial comments and suggestions on our I-Ds and works. Regards. KATO, Akihiro ---------------------- A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : FSU Key Exchange Authors : Akihiro Kato Thomas Hardjono Tetsutaro Kobayashi Tsunekazu Saito Koutarou Suzuki Filename : draft-kato-fsu-key-exchange-01.txt Pages : 26 Date : 2016-03-18 Abstract: This draft proposes an identity-based authenticated key exchange protocol following the extended Canetti-Krawczyk (id-eCK) model. The protocol is currently the most efficient among the id-eCK protocols. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-kato-fsu-key-exchange/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-kato-fsu-key-exchange-01 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-kato-fsu-key-exchange-01 ------- A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Optimal Ate Pairing Authors : Akihiro Kato Michael Scott Tetsutaro Kobayashi Yuto Kawahara Filename : draft-kato-optimal-ate-pairings-01.txt Pages : 17 Date : 2016-03-18 Abstract: Pairing is a special map from two elliptic curve that called Pairing- friend curves to a finite field and is useful mathematical tools for constructing cryptographic primitives. It allows us to construct powerful primitives. (e.g. [3] and [4]) There are some types of pairing and its choice has an impact on the performance of the primitive. For example, Tate Pairing [3] and Ate Pairing [4] are specified in IETF. This memo focuses on Optimal Ate Pairing [2] which is an improvement of Ate Pairing. This memo defines Optimal Ate Pairing for any pairing-friendly curve. We can obtain concrete algorithm by deciding parameters and building blocks based on the form of a curve and the description in this memo. It enables us to reduce the cost for specifying Optimal Ate Pairing over additional curves. Furthermore, this memo provides concrete algorithm for Optimal Ate Pairing over BN-curves [7] and its test vectors. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-kato-optimal-ate-pairings/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-kato-optimal-ate-pairings-01 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-kato-optimal-ate-pairings-01 -------------------------- A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Barreto-Naehrig Curves Authors : Akihiro Kato Michael Scott Tetsutaro Kobayashi Yuto Kawahara Filename : draft-kasamatsu-bncurves-02.txt Pages : 24 Date : 2016-03-18 Abstract: Elliptic curves with pairings are useful tools for constructing cryptographic primitives. In this memo, we specify domain parameters of Barreto-Naehrig curves (BN-curves) [8]. The BN-curve is an elliptic curve suitable for pairings and allows us to achieve high security and efficiency of cryptographic schemes. This memo specifies domain parameters of four 254-bit BN-curves [1] [2] [5] which allow us to obtain efficient implementations. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-kasamatsu-bncurves/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-kasamatsu-bncurves-02 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-kasamatsu-bncurves-02
