Cryptographic pairings
Did you know?
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… WebOct 25, 2024 · Cryptographic pairings became a hot topic after the introduction of solutions for various interesting cryptographic primitives, including identity-based non-interactive key agreement [297], one-round tripartite Diffie–Hellman key exchange [194, 195], identity-based encryption [58] and short signatures [60, 61].

In this paper we describe an efficient implementation of the Tate and Ate pairings using Barreto-Naehrig pairing-friendly curves, on both a standard PC and on a 32-bit … WebJun 12, 2024 · Bilinear pairings on elliptic curves. In practice, the pairing above is not secure for cryptographic use. Instead, we use pairings over elliptic curves. The inputs are points on an elliptic curve and the output is a number². There are multiple ways to construct pairings over elliptic curves, such as Weil, Tate, and Ate pairings. Miller’s ...
