The Math Behind PQC: Learning With Errors

Introduction Some of the winning cryptographic schemes in the NIST standardization process belonging to the latex-based cryptography family are constructed from a problem called Learning With Errors (LWE). Given a...

The mathematics behind PQC: lattices

15 Feb

Introduction A large number of post-quantum cryptography schemes are built on a mathematical structure called “lattice“, on which hard-to-solve problems can be defined even for a quantum computer. Cryptosystems belonging...

Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC)

14 Nov

Today the quantum attacks threat is a real danger. The protection of data and communications is linked to technologies that give future-proof answers, capable of thwarting threats with still partially...
