Blockchain and other Distributed Ledger Technologies (DLTs) have evolved significantly in
the last years and their use has been suggested for numerous applications due to their …

Cryptography is essential for the security of online communication, cars and implanted
medical devices. However, many commonly used cryptosystems will be completely broken …

In this paper, we present the lattice-based signature scheme Dilithium, which is a
component of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) suite that was …

• Increase noise parameter for Kyber512 In the round-2 submission of Kyber, the decryption
error for Kyber512 was rather conservative, while at the same time, there were requests to …

In the final phase of the post-quantum cryptography standardization effort, the focus has
been extended to include the side-channel resistance of the candidates. While some …

We introduce the first microarchitectural side channel attacks that leverage contention on the
CPU ring interconnect. There are two challenges that make it uniquely difficult to exploit this …

Side-channel attacks have become a severe threat to the confidentiality of computer
applications and systems. One popular type of such attacks is the microarchitectural attack …

We propose a framework for cryptanalysis of lattice-based schemes, when side information—
in the form of “hints”—about the secret and/or error is available. Our framework generalizes …

Abstract The Fiat-Shamir transform is a technique for combining a hash function and an
identification scheme to produce a digital signature scheme. The resulting scheme is known …

Modern processors expose software to information leakage through shared
microarchitectural state. One of the most severe leakage channels is cache contention …
