| Research Abstract |
Pairing-based cryptography is a type of public-key cryptography which uses pairings over elliptic curves. Pairings over elliptic curves have bilinearity and we can realize ID-based cryptography by using this property. Recently, ``new type’’pairing-based cryptosystems have been proposed based on many interesting mathematical problems. In this research, we worked about generation of elliptic curves suitable for such cryptosystems.
