ePrint Report: Exponent-VRFs and Their Applications

Dan Boneh, Iftach Haitner, Yehuda Lindell

Verifiable random functions (VRFs) are pseudorandom functions with the addition that the function owner can prove that a generated output is correct, with respect to a committed key. In this paper we introduce the notion of an exponent-VRF, or eVRF, which is a VRF that does not provide its output $y$ explicitly, but instead provides $Y = y \cdot G$, where $G$ is a generator of some finite …
