Editor’s note: since the publication of this blog post, an expanded and more technical discussion of the implementation process has been written, and is available on eprint: https://eprint.iacr.org/2022/1283. Introduction Last weekend (July 30th) a truly incredible piece of mathematical/cryptanalysis research was put onto eprint. Wouter Castryck and Thomas Decru of KU Leuven published a paper "An … Continue reading Implementing the Castryck-Decru SIDH Key Recovery Attack in SageMath

NIST Selects Post-Quantum Algorithms for Standardization
Last week, NIST announced some algorithms selected for standardization as part of their Post-Quantum Cryptography project. This is a good opportunity to recall the history of this process, observe its current state, and comment on the selected algorithms. It is important to remember that the process is not finished: round 4 has started, and should … Continue reading NIST Selects Post-Quantum Algorithms for Standardization
BAT: a Fast and Small Key Encapsulation Mechanism
In this post we present a newly published key encapsulation mechanism (KEM) called BAT. It is a post-quantum algorithm, using NTRU lattices, and its main advantages are that it is both small and fast. The paper was accepted by TCHES (it should appear in volume 2022, issue 2) and is also available on ePrint: https://eprint.iacr.org/2022/031 … Continue reading BAT: a Fast and Small Key Encapsulation Mechanism

Real World Cryptography Conference 2021: A Virtual Experience
Earlier this month, our Cryptography Services team got together and attended (virtually) the IACR's annual Real World Cryptography (RWC) conference. RWC is a fantastic venue for the latest results in real world cryptography from industry and academia. Holding this conference virtually inevitably introduced some changes: to accommodate as many time zones as possible, the daily … Continue reading Real World Cryptography Conference 2021: A Virtual Experience
