Molecular Microbiology, Volume 121, Issue 2, Page 243-259, February 2024.We describe a novel LysR‐type transcriptional regulator (LelA) which activates the expression of three Legionella pneumophila effector‐encoding genes (LegL6, LegL7 and LegU1), and is regulated by the RpoS sigma factor. Our data provides insights into the expression, evolution and distribution of this regulator and its target genes.

Faster Public-key Compression of SIDH with Less Memory [PDF]
, 2022 In recent years, the isogeny-based protocol, namely supersingular isogeny Diffe-Hellman (SIDH) has become highly attractive for its small public key size.

Efficiency of SIDH-based signatures (yes, SIDH) [PDF]
In this note, we assess the efficiency of a supersingular isogeny Diffie-Hellman (SIDH)-based digital signature built on a weaker variant of a recent identification protocol proposed by Basso et al.

An attack on SIDH with arbitrary starting curve [PDF]
, 2022 We present an attack on SIDH which does not require any endomorphism information on the starting curve. Our attack has subexponential complexity thus significantly reducing the security of SIDH and SIKE; our analysis and preliminary implementation ...

Authenticated key exchange for SIDH [PDF]
, 2018 We survey authenticated key exchange (AKE) in the context of supersingular isogeny Diffie-Hellman key exchange (SIDH). We discuss different approaches to achieve authenticated key exchange, and survey the literature. We explain some challenges that arise

High Performance Modular Multiplication for SIDH [PDF]
, 2019 The latest research indicates that quantum computers will be realized in the near future. In theory, the computation speed of a quantum computer is much faster than current computers, which will pose a serious threat to current cryptosystems.

An Adaptive Attack on 2-SIDH [PDF]
, 2020 We present a polynomial-time adaptive attack on the 2-SIDH protocol. The 2-SIDH protocol is a special instance of the countermeasure proposed by Azarderakhsh, Jao and Leonardi to perform isogeny-based key exchange with static keys in the presence of an ...

Implementing the Castryck-Decru attack on SIDH with general primes [PDF]
With the rapid progress of quantum computers in recent years, efforts have been made to standardize new public-key cryptographic protocols which would be secure against them. One of the schemes in contention was Supersingular Isogeny Diffie-Hellman (SIDH)

A Note on a Static SIDH Protocol [PDF]
, 2019 It is well known, due to the adaptive attack by Galbraith, Petit, Shani, and Ti (GPST), that plain SIDH is insecure in the static setting. Recently, Kayacan\u27s preprint A Note on the Static-Static Key Agreement Protocol from Supersingular Isogenies ...

SoK: The Problem Landscape of SIDH [PDF]
, 2018 The Supersingular Isogeny Diffie-Hellman protocol (SIDH) has recently been the subject of increased attention in the cryptography community. Conjecturally quantum-resistant, SIDH has the feature that it shares the same data flow as ordinary Diffie ...
