About the conference

The International Conference on Cryptology in India (INDOCRYPT) is an annual cryptography conference organised by the Cryptology Research Society of India (CRSI) in association with an Indian institute or organisation. The conference seeks submissions from academia, industry, and government on all theoretical and practical aspects relevant to cryptology, network security, and its related fields regarding modern computing systems (see below for Topics). This year conveys the 26th edition of the conference, which will be held in Bhubaneswar, India. Proceedings of this year's conference will be published by Springer LNCS; proceedings of previous editions of the conference can be found online.

Submission Guidelines

Instructions For Authors

High-quality papers on unpublished research and implementation experiences may be submitted. All papers must be original and not substantially duplicate work that has been published at or is simultaneously submitted to a journal or another conference or workshop. Information about submissions may be shared with the programme chairs of other conferences to detect duplication.

Submissions must be processed in LaTeX2e and must use Springer’s Lecture Notes in Computer Science (LNCS) format with default margins and font. Submissions must be anonymous, with no author names, affiliations, acknowledgements, or obvious references. Papers must be submitted electronically in PDF format. Each submission must begin with a title, a short abstract, and a list of keywords, followed by a main body, appendices (if any), and references. The main body should begin with an introduction that summarises the contributions of the paper at a level appropriate for a non-specialist reader. The length of the paper, including appendices (if any) and excluding references, should not exceed 20 pages when formatted using the LNCS style. If the authors include appendices, they should be placed after the main body and before the references. Papers must be submitted via EasyChair.

Optionally, additional supporting material can be appended to the submission. The additional supporting material should be placed after the references, well-marked, and with no prescribed form or page limit. Alternatively, the supporting material can be submitted as a separate file. Authors are encouraged to use this space to include proofs, source code, and other information allowing verification of results; unverifiable papers risk rejection. However, committee members will read the additional supporting material at their discretion, so the submission should be intelligible and self-contained without it. Submissions not meeting these requirements risk rejection without consideration of their merits.

The proceedings will be published by Springer in the Lecture Notes in Computer Science series. The final versions of the accepted papers will have a page limit of 20 pages (including appendices (if any) and excluding references). Thus, the submitted paper should represent what the authors expect to finally publish. All accepted papers must conform to the Springer publishing requirements, and authors will be required to sign Springer’s LNCS 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.
