Description

P3S3 is an international thematic Summer School to be held from June 1 to June 5, 2026, co-organized by Université Paris-Saclay (Graduate School ISN) and Institut Polytechnique de Paris at the Institut Pascal.

Data protection, security, and privacy are central challenges in modern information technologies, spanning both theoretical foundations and practical applications. The main objective of P3S3 is to provide an in-depth introduction to these topics through the presentation of several cryptographic protocols, from their underlying mathematical principles to their concrete real-world deployment. A second objective of the school is to introduce formal methods and tools for analyzing the security of these protocols. To this end, the program is structured around several main thematic areas:

cryptographic protocols: zero-knowledge proofs, homomorphic encryption, and electronic voting
formal methods for security analysis: protocols and code analysis
privacy-enhancing technologies (PETS): technical and legal aspects

P3S3 is primarily aimed at PhD students, as well as early-stage researchers, and offers a full week of lectures delivered by leading experts in these fields. In addition, by bringing together researchers from different communities, the school seeks to foster new interactions and strengthen collaborations.

Application and Registration: a 2-step procedure

To participate in the summer school, you will first have to apply, and then, after a review process, you will receive a link to register. We welcome European applications, and a few “housing” grants will be allocated to support PhD students, covering housing and registration fees.

Application

Depending on your status, information will be asked:

PhD student: CV and motivation letter
Academic & Industry: CV

There will be two rounds for applications:

First round:
- Until March 30 (23:59 Paris time).
- Notification of acceptance: after April 15.
Second round:
- From April 1 to April 15 (23:59 Paris time).
- Notification of acceptance: after May 4.
