Postdoktor innen kryptografi (FHE) i Bergen

Hva vi ser etter

We are looking for candidates with a PhD degree in Cryptography, Computer Science, Mathematics, or a closely related field to work on the two projects. The successful candidates will have a strong track record demonstrated by publications in high-impact journals and international conferences. A basic knowledge of FHE is required, and demonstrated experience with the practical application of FHE or cryptographic engineering is an advantage.

You must be highly motivated, demonstrate strong analytical skills, and you will be encouraged to nurture your own research passions. We expect the candidate to possess strong communication and collaboration skills and be fluent in English, both in academic writing and speaking. Finally, the successful candidate will have good interpersonal skills and be willing and able to contribute to Simula UiB's working environment.

Arbeidsoppgaver

The successful candidates will work on two different projects named PREMAL and SECSHARE, respectively, in Håvard Raddum's team. The focus of the two projects and the profile for their ideal candidates are described as follows.

PREMAL is a project focused on privacy-preserving machine learning using FHE. The project will investigate trade-offs between accuracy, time, and memory complexity when performing encrypted inference, and explore to what extent machine learning models can be simplified and made FHE-friendly while still being useful. The project will also investigate how to perform encrypted training and enhance the application of FHE to federated learning.

SECSHARE is a project led by the Norwegian company Mobai and is dedicated to building a privacy-preserving system for authentication using biometrics. Simula UiB leads the work package on cryptography and is responsible for designing the cryptographic protocol for the authentication system. FHE will be a central part of the system, but multi-party computation (MPC) will also play a role. The postdoc hired on SECSHARE is not expected to work full-time on the project but will also have the opportunity to develop their own research agenda in FHE or, more broadly, in privacy-enhancing technology.

The positions are both for a three-year period.
