| Outline of Final Research Achievements |
Pairing-based cryptographic schemes require elliptic or hyperelliptic curves with special properties. In this research, we study the condition that complete families of such curves are ideal, and we give the followings:
(1) There are no ideal complete families of pairing-friendly elliptic curves with embedding degree 3, 4, or 6.
(2) Many complete families, including non-cyclotomic case, of pairing-friendly elliptic curves the embedding degree 8 or 12 are non-ideal.
