Following the success of the 2021, 2022 and 2024 editions, DGA — in partnership with CREACH LABS and with the support of ANSSI, IRISA, IRMAR and the Pôle d'Excellence Cyber — is organizing the 4th edition of the Post-Quantum Cryptography workshop during the European Cyber Week 2026.

Description

At the dawn of the quantum computing era, the security of digital communications is entering a new phase. Post-quantum cryptography is now essential to protect our data and ensure its authenticity through electronic signatures, the foundation of digital trust.

This 2-day workshop brings together the academic, industrial, and institutional communities around topics ranging from the design of schemes to their implementation and evaluation.

At the agenda:

• Talks addressing strategic, regulatory and digital sovereignty challenges,
• Industry feedback on the integration of post-quantum cryptography and electronic signature solutions,
• Presentations of ongoing research and development, especially on new signature schemes, their performance and their large-scale deployment.

Call for posters

A Call for Posters is open to PhD students and postdoctoral researchers. The poster session is an opportunity to present ongoing work and to engage in discussion with specialists from a range of disciplines. Topics may include, but are not limited to:

• New post-quantum cryptographic schemes (design, security, cryptanalysis).
• Performance and optimization of post-quantum primitives.
• Software, hardware or embedded implementation, resistance to physical attacks.
• Integration, large-scale deployment and post-quantum cryptographic transition.

Each accepted poster will be the subject of a short 3-minute talk. The best poster will be awarded a prize during the event.

• Submission

  One-page abstract in English, with name, affiliation and contact details
