Solidity bilinear pairing
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. It allows strong encryption with small signature sizes. See more A pairing is called admissible pairing if it is efficiently computable. The only admissible pairings that are suitable for cryptography are the Weil and Tate pairings on algebraic curves and their variants. Let be the … See more Tate pairings use Miller's algorithm, which is essentially the double-and-add algorithm for elliptic curve point multiplication combined with evaluation of the functions used in … See more The Tate pairing is a map: defined as: where , is any representative in a equivalenceclass in and is the set ofequivalence classes of under theequivalence relation .

WebFeb 4, 2011 · Many pairing-based schemes and protocols have been proposed. However, no PVSS scheme using bilinear pairings is proposed. This paper presents the first pairing-based PVSS scheme. In the random oracle model and under the bilinear Diffie-Hellman assumption, the authors prove that the proposed scheme is a secure PVSS scheme. WebThe Weil pairing on elliptic curves, and the Tate pairing on elliptic and hyperelliptic curves are explained with a computational approach in mind. The second section introduces …
