Hi cfrg folks,

Elliptic curves with a special map called a pairing allow cryptographic
primitives to achieve functions or efficiency which cannot be realized
by conventional mathematical tools. For example, ZSS signature is one of
these primitives.

We have recently submitted an I-D on Barreto-Naehrig curves (BN-curves)
which provide efficient operations of a pairing.
The I-D specifies parameters of BN-curves which are particularly useful
for realization of efficient cryptographic schemes based on pairing and 
parameters of BN-curves which are compliant with ISO/IEC 15946-5.

We will propose I-Ds on computation of pairing and pairing-based 
primitives in order to contribute to IETF community in the near future.

We would appreciate your comments and suggestions on our I-D and works.

    Elliptic curves with pairing are useful tools for constructing
    cryptographic primitives.  In this memo, we specify domain parameters
    of Barreto-Naehrig curve (BN-curve) [5].  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 two 254-bit BN-curves [1] [2] which allow us to obtain
    efficient implementations and domain parameters of 224, 256, 384, and
    512-bit BN-curves which are compliant with ISO/IEC 15946-5[3].
    Furthermore, this memo organizes differences between types of
    elliptic curves specified in ISO document and often used in open
    source softwares, which are called M-type and D-type
