Investigation on lattices- and code-based post-quantum signature cryptosystems

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)...

Investigation on post-quantum digital signature systems based on multivariate equations

The NIST Post-Quantum Cryptography standardisation process has called for new algorithms, for the purpose of finding and standardising new cryptographic algorithms, able to withstand attacks enabled by future quantum processing progress. Digital signature schemes are fundamental for validating authenticity and integrity of digital documents. In...
