WebThe Weil pairing requires us to find a field containing all r -torsion points, while the Tate pairing only requires the field to contain the r th roots of unity. When the embedding degree is greater than 1, these conditions are identical. For efficiency, when the embedding degree k is at least 2, one of the inputs is restricted to a subfield. Web2 where these properties hold: the Weil and Tate pairings prove the existence of such constructions. Typically, G 1 is an elliptic-curve group and G 2 is a ﬁnite ﬁeld. 3 Complexity Implications The construction of a bilinear map comes with a number of complexity implications.

WebIn simplified notation, a bilinear map is a pairing that has the property: Pair(a · X, b · Y) = Pair(b · X, a · Y) In two of the more well-known IDE systems, the Weil (pronounced vay, rhyming with the English word way) and Tate pairings, the · operator above refers to multiplication of a point on an elliptic curve by integers [9]. WebDeﬁnition of a Bilinear Map Let G 1, G 2, and G t be cyclic groups of the same order. Deﬁnition A bilinear map from G 1 ×G 2 to G t is a function e : G 1 ×G 2 →G t such that for all u ∈G 1, v ∈G 2, a,b ∈Z, e(ua,vb) = e(u,v)ab. Bilinear maps are called pairings because …
