| Research Abstract |
We worked for developing algorithms for computing pairings and scalar multiplication over elliptic curves in order to implement pairing-based cryptography on IC cards efficiently. We obtained results, for example, about efficient algorithms on computing pairings and scalar multiplication over elliptic curves over finite fields of small characteristic using elliptic nets.
