WebAug 20, 2015 · Let A, B, C be vector spaces. A map f: A × B → C is said to be bilinear if for each fixed element b ∈ B, f (., b): A → C is a linear map. Similarly, for each fixed element of A. Matrix multiplication is an example of a bilinear map.Following my definition, I can prove that it is a bilinear map, but I don't understand the intuitive idea ... If symmetric, pairings can be used to reduce a hard problem in one group to a different, usually easier problem in another group. For example, in groups equipped with a bilinear mapping such as the Weil pairing or Tate pairing, generalizations of the computational Diffie–Hellman problem are believed to be infeasible while the simpler decisional Diffie–Hellman problem can be easily solved using the pairing function. Th…
