NIST is in the process of evaluating public-key digital signature algorithms for potential
standardization to protect sensitive information into the foreseeable future, including after the …

Two-factor authentication provides a strong defense against account compromise. However,
traditional two-factor authentication schemes cannot provide users with much flexibility and …

Post-quantum cryptographic (PQC) algorithms, especially those based on the learning with
errors (LWE) problem, have been subjected to several physical attacks in the recent past …

Abstract The Domain Name System Security Extensions (DNSSEC) provide authentication
of DNS responses using digital signatures. DNS operates primarily over UDP, which leads …

Physical attacks are serious threats to cryptosystems deployed in the real world. In this work,
we propose a microarchitectural end-to-end attack methodology on generic lattice-based …

The standardization of the hash-based digital signature scheme SPHINCS+ proceeds faster
than initially expected. This development seems to be welcomed by practitioners who …

Quantitative analyses of the costs of cryptographic attack algorithms play a central role in
comparing cryptosystems, guiding the search for improved attacks, and deciding which …

Despite considerable progress in theoretical post-quantum cryptography we have yet to see
significant advances in its practical adoption. The necessary protocol modifications need to …

Recently, the construction of cryptographic schemes based on hard lattice problems has
gained immense popularity. Apart from being quantum resistant, lattice-based cryptography …

CRYSTALS-Kyber is a promising post-quantum encryption candidate and has been
selected for standardization. However, its operational efficiency faces challenges due to …
