Un institut de recherche en informatique recherche un stagiaire pour développer des techniques de fuzzing guidées par des modèles DY adaptées aux protocoles d'e-voting. Le candidat, qu'il soit à la recherche d'une carrière académique ou non, bénéficiera d'un encadrement dédié tout en étant encouragé à contribuer de manière indépendante. La rémunération est de 4,50 € de l'heure avec des avantages tels que la restauration subventionnée et un accès aux formations professionnelles.
We are seeking a Master’s intern or a PhD candidate to join our puffin [1] team and design Dolev‑Yao (DY) model‑guided fuzzing techniques [2] amenable to e‑voting protocols.
First of all, the candidate will get familiar with formal DY models, fuzzing [2], as well as with the existing code base of SwissPost [4].
There are several challenges to adapting DY fuzzing techniques to e‑voting and to SwissPost. First, e‑voting protocols differ from mere internet protocols in that they involve complex workflows and interactions between different actors, implemented as different micro‑services in SwissPost. Therefore, the intern will have to design a way to fuzz such complex workflows in order to animate e‑voting ceremonies and elections. Second, the security properties of e‑voting protocols are different and more complex than those of authentication protocols such as TLS. Therefore, the candidate will have to design objective oracles capable of detecting violations of e‑voting security properties. Finally, SwissPost is supposed to resist strong threat models, including insider threats and collusions between different actors. Therefore, the candidate will have to design dynamic actor compromise within the DY fuzzer.
The precise direction this project will take shall be agreed upon with the candidate at the beginning of the project. The candidate will benefit from dedicated engineering support from our research engineer working on the project, while also being expected to contribute independently to the software development efforts. Should we find any vulnerability, we would follow standard and ethical responsible disclosure practices.
Internship candidates interested in pursuing an academic career may also consider continuing towards a PhD, as we have additional funding available for promising candidates.
