Information about the department

The Department of Computer Science and Engineering is a joint department at Chalmers University of Technology and the University of Gothenburg, with activities on two campuses in the city of Gothenburg. The department has around 210 employees from over 30 countries. Our research has a wide span, from theoretical foundations to applied systems development. We provide high quality education at Bachelor's, Master's and graduate levels, offering over 120 courses each year. We also have extensive national and international collaborations with academia, industry and society.

Major Responsibilities

We are looking for an excellent, motivated, self-driven doctoral student to work in the area of information security and cryptography. The position is for up to five years at the Department of Computer Science and Engineering, within the group of Prof. Katerina Mitrokotsa who is doing research in cryptographic protocols that guarantee reliable authentication, privacy-preservation and verifiable delegation of computation. The topic of this project is the security and privacy issues of resource-constrained devices (e.g., sensors) that rely on external untrusted servers to perform computations. More precisely, the student will work on developing efficient authentication and verifiable delegation of computation mechanisms that provide: i) provable security guarantees, and ii) rigorous privacy guarantees. The overall aim of the PhD position will be to design and evaluate cryptographically reliable and privacy-preserving authentication and verifiable delegation of computation protocols. The research shall also consider the case where multiple clients outsource joint computations to untrusted cloud servers. Security and privacy proofs in this important setting are significantly more challenging, as they involve secure multi party computation between many untrusted peers.

The PhD student will be supervised by Prof. Katerina Mitrokotsa.
Katerina Mitrokotsa's research is currently funded by the European Commission and the Chalmers ICT Areas of Advance and the Swedish Research Council.

Position Summary

Full-time temporary employment. PhD student positions are limited to five years and normally include 20 per cent departmental work, mostly teaching duties. Salary for the position is as specified in Chalmers' general agreement for PhD student positions. Currently the starting salary is 27,835 SEK a month before tax. The position is intended to start in Sept 2017.


The PhD student is expected to have a MSc degree or equivalent, and strong background in mathematics and/or theoretical computer science, with some background in cryptography. The position is fully funded for up to five years.
Experience in one or more domains such as cryptography, design of protocols, secure multi-party computation and differential privacy is beneficial. Mathematical maturity is essential. As for all PhD studies, a genuine interest and curiosity in the subject matter and excellent analytical and communication skills, both oral and written, are needed.
Students that are expected to receive the MSc degree (or equivalent) in 2017 are also encouraged to apply. Knowledge of Swedish is not a prerequisite for applying since English is our working language for research, and we publish internationally. Both Swedish and English are used in undergraduate courses. Half of our researchers and PhD students at the department come from more than 30 different countries.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
