ePrint Report: Simultaneously simple universal and indifferentiable hashing to elliptic curves
Dmitrii Koshelev
The present article explains how to generalize the hash function SwiftEC (in an elementary quasi-unified way) to any elliptic curve $E$ over any finite field $\mathbb{F}_{\!q}$ of characteristic $> 3$. The new result apparently brings the theory of hash functions onto elliptic curves to its logical conclusion. To be more precise, this article provides compact formulas that define a hash function $\{0,1\}^* \to E(\mathbb{F}_{\!q})$ (deterministic and indifferentible …
