We present an end-to-end (equivalent) key recovery attack on the Dilithium lattice-based
signature scheme, one of the top contenders in the NIST postquantum cryptography …

The random oracle model (ROM) enjoys widespread popularity, mostly because it tends to
allow for tight and conceptually simple proofs where provable security in the standard model …

Post-quantum cryptography has known a Cambrian explosion in the last decade. What
started as a very theoretical and mathematical area has now evolved into a sprawling …

Schnorr's signature scheme provides an elegant method to derive signatures with security
rooted in the hardness of the discrete logarithm problem, which is a well-studied assumption …

This paper analyses security of concrete instantiations of EdDSA by identifying exploitable
inconsistencies between standardization recommendations and Ed25519 implementations …

Digital contact tracing apps allow to alert people who have been in contact with people who
may be contagious. The Google/Apple Exposure Notification (GAEN) system is based on …

Abstract The Fiat-Shamir transformation is a widely employed technique in constructing
signature schemes, known as Fiat-Shamir signature schemes (FS-SIG), derived from secure …

This work introduces the first differential side-channel analysis of the Picnic Signature
Scheme, an alternate candidate in the ongoing competition for post-quantum cryptography …

The deterministic ECDSA and EdDSA signature schemes have found plenty of applications
since their publication, eg, block chain and Internet of Thing, and have been stated in RFC …

Security against side-channels and faults is a must for the deployment of embedded
cryptography. A wide body of research has investigated solutions to secure implementations …
