■Title : Cryptographic Standardization and Mathematics:Notes from Standardizing Pairing-Friendly Curves
■Place : IMI Auditorium(W1-D-413) and Live streaming with Zoom
■Speaker : Yumi Sakemi(GMO Connect, Inc. / GMO Internet Group, Inc.)
■Attendance: 34(Students: 14; Staff: 14;Others: 6)
In this talk, the speaker discussed the following topics regarding cryptographic standardization
and mathematics:
* The concept and necessity of standardization (de jure/forum/de facto standards, and the
Great Baltimore Fire example).
* An overview of the IETF and the process of developing RFCs.
* Technical challenges in standardizing pairing-friendly curves and their mathematical solutions.
The speaker emphasized that mathematics is essential for solving practical technical challenges
in standardization, such as elliptic curve point compression and the arithmetic and representation
of extension fields.
This talk highlighted the importance of international standardization beyond academic publications
and demonstrated how mathematics helps solve real-world technical challenges.
