PQCrypto 2024
The 15th International Conference on Post-Quantum Cryptography
PQCrypto 2024
June 12-14, 2024
Mathematical Institute, University of Oxford (UK)
Introduction
The aim of PQCrypto is to serve as a forum for researchers to present results and exchange ideas on the topic of cryptography in an era with large-scale quantum computers.
After fourteen successful PQCrypto conferences (2006 in Leuven, 2008 in Cincinnati, 2010 in Darmstadt, 2011 in Taipei, 2013 in Limoges, 2014 in Waterloo, 2016 in Fukuoka, 2017 in Utrecht, 2018 in Fort Lauderdale, 2019 in Chongqing, 2020 in Paris (online), 2021 in Daejeon (hybrid), 2022 (online), in Maryland 2023), we are looking forward to PQCrypto 2024.
The conference will take place at the University of Oxford, Mathematical Institute. The dates are June 12–14, 2024.
We are on twitter as @PQCryptoConf for updates.
Affiliated Event - newtpqc
PQCrypto 2024 will be preceded by a 2-day workshop, The New Trends in Post-Quantum Cryptography workshop, or newtpqc. It will take place at the Mathematical Institute, University of Oxford (UK) on Monday 10 June and Tuesday 11 June 2024.
The goal of the workshop is to discuss the most recent and exciting trends of post-quantum cryptography. Ten world-class researchers will give keynote talks on cutting-edge topics that will play an important part in post-quantum cryptography in the years to come.
Further information can be found in the newtpqc website.

Call for Papers
Call for papers in pdf format.
Original research papers on all technical aspects of cryptographic research related to post-quantum cryptography are solicited. Topics of interest include (but are not restricted to):
- Cryptanalysis of post-quantum systems, and quantum cryptanalysis.
- Cryptosystems that have the potential to be safe against quantum computers such as: code-based, hash-based, isogeny-based, lattice-based, and multivariate constructions.
- Implementations of, and side-channel attacks on post-quantum cryptosystems.
- Security models for the post-quantum era.
Instructions to authors
Accepted papers will be published in Springer's LNCS series. Submissions must be anonymous. Submissions must not exceed 30 pages, including appendices and excluding references, and must be in a single-column format in 10pt fonts using the default llncs class without adjustments. The submission should begin with a title, a short abstract, and a list of key words. Its introduction should summarize the contributions of the paper at a level appropriate for a non-specialist reader. Reviewers are not required to read appendices; submissions are expected to be intelligible and complete without them. Submissions must not substantially duplicate work that any of the authors has published in a journal or a conference/workshop with proceedings, or has submitted/is planning to submit before the author notification deadline to a journal or other conferences/workshops that have proceedings.
