The signature scheme qTESLA

qTESLA is a family of post-quantum signature schemes based on the hardness of the decisional Ring Learning With Errors (R-LWE) problem. The scheme is an efficient variant of the Bai-Galbraith signature scheme —which in turn is based on the “Fiat-Shamir with Aborts” framework by Lyubashevsky— adapted to the setting of ideal lattices.

qTESLA was submitted to NIST's post-quantum standardization project in November 2017 and is accepted for the first round of the competition.
