In the last decade, development in quantum computing has threatened the security of current public-key cryptography. For this reason, the American National Institute of Standards and Technology (NIST) has organized a competition-like process to standardize new quantum-resistant public-key encryption and digital signature schemes. This research project aims to give a general overview of post-quantum lattice-based cryptography and analyze and compare the submitted lattice-based public-key encryption schemes over performance, security, distinguishing features and potential vulnerabilities

As quantum-resistant cryptosystems will soon benecessary, the NIST has organized a contest aim-ing to its standardization. The proposed schemesmust be evaluated and thoroughly investigated tonotably ensure their security and compare their per-formance. This paper will explore various lattices-based (pqNTRUSign, BLISS, Dilithium, Falcon,qTesla) and code-based (RaCoSS, pqsigRM) dig-ital signature schemes. An efficiency and security-based comparison is conducted among them andtheir features are discussed.
