Instructions for Authors

Submissions must use the Springer LNCS format with the default margins and font, with one modification: submissions should display page numbers (e.g. by adding \pagestyle{plain} to the document preamble). Submissions may contain at most 30 pages including the title page, bibliography, and figures. Optionally, any amount of clearly marked supplementary material may be supplied, following the main body of the paper or in separate files; however, reviewers are not required to read or review any supplementary material, and submissions are expected to be intelligible without it. Significant changes between the published version and the submitted version should be approved by the program committee.

Submissions should begin with a title and abstract, followed by an introduction that summarizes the paper's contribution in a manner that is understandable to a general cryptographic audience. Submissions must be anonymous, with no author names, affiliations, or obvious references; all submissions will be blind-refereed. (It is acceptable to post full versions to the IACR ePrint archive, give public talks, etc., consistent with the IACR author guidelines.) Submissions must not substantially duplicate published work or work that has been submitted in parallel to any other journal or conference/workshop with published proceedings. Accepted submissions cannot appear in any other conference or workshop that has published proceedings. The IACR reserves the right to share information about submissions with other program committees to check for violations of these rules. The conference will follow the IACR Policy on Irregular Submissions; authors may wish to consult the IACR Guidelines for Authors.

Submissions not meeting the guidelines above may be rejected without consideration of their merits.

All accepted papers must conform to the Springer publishing requirements, and authors will be required to sign the IACR Copyright form when submitting the proceedings version of their paper. By submitting a paper, the authors agree that if the paper is accepted, one of the authors will present the paper at the conference and, in addition, will grant permission to the IACR to distribute the presentation materials as per the IACR copyright and consent form. When applicable, we encourage authors to include in their supplementary materials their responses to reviews from prior IACR events, as described in the Guidelines for Authors. During submission, authors will be asked to indicate any conflicts of interest with the PC members, per the IACR CoI policy, also described below.

Conflicts of Interest

Authors, program committee members, and reviewers must follow the IACR Policy on Conflicts of Interest, available from

In particular, the authors of each submission are asked during the submission process to identify all members of the Program Committee who have an automatic conflict of interest (COI) with the submission. A reviewer and an author have an automatic COI if:

Any further COIs of importance should be separately disclosed3. It is the responsibility of all authors to ensure correct reporting of COI information. Submissions with incorrect or incomplete COI information may be rejected without consideration of their merits.

1 Sharing an institutional affiliation means working at the same location/campus of the same company/university. It does not include separate universities of the same system nor distant locations of the same company.
2 Jointly authored work refers to jointly authored papers and books, whether formally published or just posted online, resulting from collaboration on a scientific problem. It usually does not include joint editorial functions, like a jointly edited proceedings volume. For online publication, the first posting (not revisions) determines the relevant date. Multiple versions of a paper (conference, ePrint, journal) count as a single paper.
3 COIs are not restricted to automatic ones, others being possible. COIs beyond automatic COIs could involve financial, intellectual, or personal interests. 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 chairs or editor any circumstances that they think may create bias, even if it does not raise to the level of a COI. The editor or program chair will decide if such circumstances should be treated as a COI.
