WebApr 19, 2016 · 1 Answer. You need non-degeneracy in both arguments. For example, let ϕ ∈ V ∗ be non-zero and define B: K × V → K, B ( λ, v) = ϕ ( λ v). Then B ( λ, v) = 0 for all v ∈ V implies λ = 0, but B is not a perfect pairing if dim ( V) ≥ 2. Now assume that B is non-degenarate in both arguments. Denote by A: V → W ∗ the operator ... 北関東自動車道 sa グルメPairings are used in encryption algorithms, such as identity-based encryption (IBE), attribute-based encryption (ABE), (inner-product) predicate encryption, short broadcast encryption and searchable encryption, among others.
