CHES 2027

September 6–9, 2027

Cancún, Mexico

CHES 2027 introduces an "extended-review long paper" format spanning two issues.
Please note that the review process for some long papers may therefore take longer.
See the Instructions for Authors for details.

Please note that the second CHES 2027 submission deadline, ches2027_2,
coincides with the CHES 2026 conference dates.
If you plan to attend CHES 2026, please consider finishing your submission early.

Paper Submission

The deadline to submit a paper to Volume 2027 Issue 1 has passed.
You can still access the Submission Server for Volume 2027 Issue 1 to view submitted papers.
The submission server for Volume 2027 Issue 2 is not yet open.
Please check back later.

Instructions for Authors

Papers are submitted to the journal IACR Transactions on Cryptographic Hardware and Embedded Systems (TCHES). TCHES has four submission deadlines per year, corresponding to the four issues of a yearly volume. Papers accepted for publication in TCHES are presented at the corresponding CHES conference. Each year, the CHES Program Chairs and Program Committee act as the TCHES Editors-in-Chief and Editorial Board.

Format

A submitted paper must be written in English and be anonymous, with no author names, affiliations, acknowledgments, or any identifying citations. It should begin with a title, a short abstract, and a list of keywords. The introduction should summarize the contributions of the paper at a level appropriate for a non-specialist reader. Submissions should be typeset in the LaTeX style available at https://tches.iacr.org/index.php/TCHES/submission, noting that TCHES only accepts electronic submission in PDF format. Please use the submission mode (\documentclass[submission]{iacrtrans}) that displays line numbers to ease the review process.

The page limit is up to 20 pages, including all figures, tables, and appendices, but excluding the bibliography. Appendices are also reviewed and should appear before the bibliography. Authors are encouraged to include additional supplementary material needed to validate the content, such as test vectors or source code, as separate files.

In exceptional cases, where additional details such as proofs or experimental results are deemed essential, long papers of up to 40 pages may be allowed. Submission of long papers requires pre-approval by the Editors-in-Chief. Authors must request pre-approval no later than one week before the submission deadline. The request must specify the number of additional pages required, provide a justification for the long paper, and include a draft of the paper. When submitted, long papers need to be marked as such by checking the respective box in the submission system and by annotating the title with "Long Paper:". Authors also need to include the justification for long papers in the supplementary material. Long papers submitted without pre-approval will be returned without review.

A long paper may be designated by the Editors-in-Chief as an extended-review long paper spanning two issues. This designation may be made during the pre-approval process, based on the length, scope, complexity, expected review effort, and operational feasibility of the review process; in this case, authors will be notified together with the pre-approval notification. Alternatively, the designation may be made during the review process based on reviewer feedback; in this case, authors will be notified before the start of the rebuttal phase. In both cases, the rebuttal phase and final decision are deferred to the subsequent issue.

TCHES solicits submission of Systematization of Knowledge (SoK) papers, i.e., papers whose goal is to review and contextualize existing literature in a particular area in order to systematize existing knowledge. To be considered for publication, SoK papers must provide significant added value beyond prior work, such as novel insights or reasonably questioning previous assumptions. Authors should highlight SoK papers by annotating the title with "SoK:".

Warning Submissions not meeting these guidelines risk rejection without consideration of their merits.

Regulations

The review process for TCHES, Volume 2027, Issues 1–4, will be governed by the following regulations:

  • Authors of submitted papers are highly encouraged to check the TCHES FAQ for answers to questions related to policy and procedures governing TCHES (e.g., changing authors, withdrawing a paper, resubmission rules, etc.).
  • TCHES follows IACR policy, i.e., with respect to irregular submissions: any submission deemed to be irregular (e.g., which has been submitted, in parallel, to another conference with proceedings), will be instantly rejected. IACR reserves the right to share information about submissions with other program committees and editorial boards to ensure strict enforcement of the policy.
  • TCHES follows IACR policy with respect to conflicts of interest that could prevent impartial review. A conflict of interest is considered to occur automatically whenever one (co-)author of a submitted paper and an Editorial Board member
    • were advisee/advisor at any time,
    • have been affiliated to the same institution in the past 2 years,
    • have published 2 or more jointly authored papers in the past 3 years, or
    • are immediate family members.
    For an interpretation of the above reasons, please refer to the IACR policy on CoIs (https://www.iacr.org/docs/conflicts.pdf). Note that conflicts may also arise for reasons other than those just listed. Examples include closely related technical work, cooperation in the form of joint projects or grant applications, business relationships, close personal friendships, instances of personal enmity.
  • Full transparency is of utmost importance, authors and reviewers must disclose to the Editors-in-Chief any circumstances that they think may create bias, even if it does not raise to the level of a CoI. At the time of submission, authors are required to
    1. make a declaration regarding any conflicts of interest (including reasons for the conflict), and
    2. guarantee that at least one author will be physically present at the associated CHES conference to present the paper if the submission is accepted for publication in TCHES.
  • Each paper will be double-blind reviewed by at least three members of the Editorial Board.
  • Submissions that deanonymize the authors, either directly, by including authors names or affiliations, or indirectly, e.g., by including acknowledgments or through file names or comments in the supplementary material, risk rejection without review.
  • TCHES supports and follows the IACR policy on the use of artificial intelligence in the preparation, submission, and review of papers. Authors and reviewers are expected to comply with this policy:
  • In order to improve the quality of the review process, authors are given the opportunity to submit a rebuttal (between the indicated dates) after receiving the associated reviews.
  • The review process outcome is either an outright accept or reject decision, or one of two deferred decision types. Specifically, "minor revision" means the paper is conditionally accepted and assigned a shepherd to verify the revision is adequate, while "major revision" means the authors are invited to submit a revision of their article to one of the following two submission deadlines; a later re-submission will be treated as a new paper.
  • When submitting a major revision, follow the instructions in the submission system to indicate that the paper is a major revision and to provide the ID of the earlier submission in the Comments to Editors-in-Chief field of the submission. To ensure consistency, the reviewers assigned for a revised paper are ideally the same as for the original submission.
  • Resubmission of papers that have previously been rejected from TCHES is only allowed after major modifications and approval by the Editors-in-Chief prior to submission. Requests must be sent to the Editors-in-Chief by email to [email protected] at least one week before the submission deadline and must be accompanied by a document explaining the differences from the original submission and describing how the suggestions in the previous reviews have been addressed or otherwise considered, together with a draft of the revised paper. Except in extenuating circumstances, such requests will not be granted if the resubmission is within one year after the original submission.
  • Resubmission of papers that have previously received a “reject & resubmit” decision from TCHES is only allowed after significant modifications and approval by the Editors-in-Chief prior to submission. Requests must be sent to the Editors-in-Chief by email to [email protected] at least one week before the submission deadline and must be accompanied by a document explaining the differences from the original submission and describing how the suggestions in the previous reviews have been addressed or otherwise considered, together with a draft of the revised paper. Except in extenuating circumstances, such requests will not be granted if the paper is resubmitted at the immediately following submission deadline.
