    New post-quantum digital signature proposals: the second NIST competition
    16 Oct

    Introduction In July 2023, NIST announced four winning algorithms in the post-quantum competition, marking an important step forward in the transition process. The selected algorithms were CRYSTALS-Kyber for key negotiation...

    Falcon: digital signature based on NTRU
    31 Jul

    Introduction NIST’s Post-Quantum standardization process has identified two cryptographic schemes based on lattice theory within digital signatures: CRYSTALS-Dilithium and Falcon. Within modern cryptographic communication protocols, these solutions will replace the...

    CRYSTALS-Dilithium: LWE-based digital signature
    31 May

    Introduction NIST’s Post-Quantum standardization process identified two cryptographic schemes to be intended as “primary” solutions. With regard to Key Encapsulation Mechanisms (KEMs), key derivation schemes, CRYSTALS-Kyber was selected, while from...

    The Math Behind PQC: Learning With Errors
    27 Mar

    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...

    Key Negotiation in the Post-Quantum Era
    09 Sep

    Introduction Cryptography, understood as the set of information protection schemes, is typically divided into symmetric or private key cryptography and asymmetric or public key cryptography. Schemes or protocols that exploit...

    Post-Quantum Cryptography (PQC): a classical solution to the quantum threat
    13 Jul

    Introduction Public key (or asymmetric) cryptography is one of the bases on which all communication protocols rest which, starting from an insecure channel, must achieve multiple security properties, such as...
