The aim of PQCrypto is to serve as a forum for researchers to present results
and exchange ideas on cryptography in an era with large-scale quantum computers.
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):

• Cryptosystems that have the potential to be safe against quantum computers such as: code-based, hash-based, isogeny-based, lattice-based, multivariate-based and MPC-in-the-head constructions.
• Cryptanalysis of post-quantum systems, and quantum cryptanalysis.
• Implementations of, and side-channel attacks on, post-quantum cryptosystems.
• Integration of and migration to post-quantum cryptography.
• Security models for the post-quantum era.

Submission Guidelines

Accepted papers are planned to be published in Springer's LNCS series. Submissions must not exceed 30 pages, excluding appendices and references, and must be in a single column format in 10pt fonts using the default llncs class without adjustments. Additional material (datasets, code, long machine proofs, etc.) can be submitted as separate file. Reviewers are not required to read appendices and additional material, and submissions are expected to be intelligible and complete without
them.

If the submission is accepted, the length of the final version is at most 35 pages excluding references, in the llncs class format. The additional material will not be part of the conference proceedings.

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.

The review process is double-blinded. 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. Submissions ignoring these guidelines may be rejected without further consideration.

All papers must be submitted with a meaningful abstract by the initial submission deadline. This is a firm deadline. Papers not registered by this deadline will not be considered. Authors may update or withdraw their submission at any time between the initial and final submission deadline.

Schedule

Reviewing will proceed in two rounds. Authors will receive the first round of reviews and will be invited to respond to the reviews with a text-based rebuttal. Reviewers will consider the rebuttal and make a final decision on the paper: accept, reject, or accept with shepherding. A paper accepted with shepherding will be given a list of required changes by the reviews, and a member of the program committee will work with the authors to implement the changes before the final version deadline.

Important dates (AoE):

• Initial submission deadline: November 17, 2026
• Final submission deadline: November 24, 2026
• Rebuttal phase: January 18 - 25, 2027
• Notification of acceptance: February 3, 2027
• Final version due: February 24, 2027
