A post-quantum digital signature scheme based on supersingular isogenies
Abstract
We present the first general-purpose digital signature scheme
based on supersingular elliptic curve isogenies secure against quantum
adversaries in the quantum random oracle model with small key sizes.
This scheme is an application of Unruh’s construction of non-interactive
zero-knowledge proofs to an interactive zero-knowledge proof proposed
by De Feo, Jao, and Plut. We implement our proposed scheme on an x86-
64 PC platform as well as an ARM-powered device. We exploit the stateof-the-art
techniques to speed up the computations for general C and
assembly. Finally, we provide timing results for real world applications.
