Qtesla signature. In summary the qtesla family of post quantum signature schemes oers great exibility by allowing a selection of parameters and schemes that exhibit dierent degrees of performance and security. In each case design decisions have been taken towards enabling ecient yet simple and compact implementations. Tesla tends to start off the production line for a new car first with a founders series not available to the general public car and then the first 1000 production vehicles are signature cars.
The most relevant features of qtesla are summarized as follows. Qtesla is the result of a long line of research beginning with a signature scheme proposed by bai and galbraith in 2014 which is based on the fiat shamir construction of lyubashevsky 2012. Introduction qtesla is a family of post quantum lattice based signature schemes based on the decisional r lwe problem the result of a long line of research selected.
Theyre fully loaded with all the options i th. A proposal for qtesla was submitted to the us national institute of standards and technology nist post quantum cryptography project. Provably secure lattice based digital signature scheme qtesla principal and auxiliary submitters.
Qtesla is a software library written in the c language that contains efficient and compact implementations of the lattice based digital signature scheme qtesla.
