This year, the 20th International Workshop on Security (IWSEC 2025) calls for posters that focus on any relevant topic of the workshop. Posters should present on-going study, idea, or project that is not mature yet, and interesting as work in progress. Student projects (Bachelor, Master, or PhD) and related studies are also welcome. Posters must fit within an A0 size space (118.9 cm (height) and 84.1 cm (width) / 46.8 in (height) and 33.1 in (width)). Posters will be presented as an interactive presentation style. Poster boards will be provided at the poster presentation date.

• Submission deadline: October 3, 2025 (AoE)
• Notification of acceptance: a couple of days from the submission deadline.

The list of accepted posters will be available through the workshop web page. NO PAPER proceedings will be published regarding the posters. Instead, IWSEC 2025 will provide a space for each poster at the IWSEC 2025 poster session room.

Basically, copyrights of any content for the poster presentations are retained by the authors; we WILL NOT impose any restrictions on the poster authors to submit the contents to other journals/conferences in the future.

However, the authors must take considerable care in publishing the documents at the workshop web page. Every published document is on POSTER AUTHORS’ RESPONSIBILITY. IWSEC 2025 accepts no responsibility and no liability for any loss resulting from the published documents. IWSEC 2025 does not endorse documents that violate any law or infringe the rights of any third party.

Prizes will be awarded to the authors of the Best Poster(s). Program Committees will select awards during the conference.

Poster Chair: Toshiki Shibahara (NTT, Japan)
