| In recent years, the bilinear pairings, namely the Weil pairing of algebraic curves, have initiated some new fields in cryptography, and many excellent ID-based signature schemes from pairings have been proposed. However, we notice that ID-based threshold signature schemes today are far rarer than basic ID-based signature schemes. In order to fill this void, in this paper, we would like to present a new ID-based robust threshold signature scheme from bilinear pairings. Any or more members in our scheme can cooperate to generate a valid ID-based signature, while or less can’t. In addition, our scheme also enjoys robustness. |
