Title: “BLISS: Bimodal Lattice Signature Scheme”
Short abstract: “In 2009, Lyubashevsky proposed the first provably secure lattice-based signature using the Fiat-Shamir paradigm. It’s security depends on a rejection step during the signature procedure. For this rejection sampling technique to be efficient, one must use a large distribution for the nonce resulting in large signatures. A few years later, Ducas and al. proposed a new scheme called BLISS optimizing this crucial step of rejection to decrease the overall size of the signature.”
