Efficient software implementation of ring-LWE encryption

2015 · Lirias

Abstract. Present-day public-key cryptosystems such as RSA and Elliptic Curve Cryptography (ECC) will become insecure when quantum computers become a reality. This paper presents the new state of the art in efficient software imple-mentations of …

A Unified Cryptoprocessor for Lattice-based Signature and Key-exchange

2022 · arXiv (Cornell University)

We propose design methodologies for building a compact, unified and programmable cryptoprocessor architecture that computes post-quantum key agreement and digital signature. Synergies in the two types of cryptographic primitives are used to make the cryptoprocessor …
