Jobbannons

We are looking for a PhD student to join the Crypto Team and Security Group at Chalmers with Christoph Egger as main supervisor. Depending on the interests of the applicant, possible research topics include fine-grained and bounded space cryptography, realization of idealized models, relationship between cryptographic notions, and similar topics in foundational cryptography. Exploring connections to statistical security notions and formal methods is possible. One or two extended research visits are encouraged during the doctoral study.

Project overview

• In Bounded Space Cryptography we are working with adversaries that are not restricted in their runtime but have limited memory and are trying to achieve basic cryptographic tasks that are secure against such adversaries.
• Idealized Models are simplifications made in proofs for real-world cryptographic protocols. We often know that this is an oversimplification in general and can hide attacks. We are interested in studying under which circumstances the simplifications can be justified.
• Cryptography relies on unproven assumptions like the hardness of factoring. Studying Relations between Cryptographic Notions asks the question of the type "If I can build public key encryption, can I also always have signature schemes?" and proves whether such statements are true or false.

Information about the division and the department

The Department of Computer Science and Engineering is a joint department at Chalmers University of Technology and the University of Gothenburg. The department has around 300 employees from over 30 countries. Our research covers 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 have extensive national and international collaborations with academia, industry, and society.

The PhD student will join a world-leading research environment at the Chalmers Security and Privacy Lab and Crypto Team.The security and privacy lab consists of more than 20 established researchers and covers a wide range of privacy both from a theoretical and practical perspective. The Crypto Team currently has two faculty members and four PhD students with a focus on foundations of cryptography as well as cryptographic primitives with advanced properties.

Our aim is to actively improve our gender balance in both our department and division. We therefore strongly encourage applicants from historically-excluded groups to our positions, such as women and non-binary individuals. As an employee of Chalmers and CSE department, students are given the opportunity to contribute to our active work within the field of equality and diversity.

Main responsibilities

• Research in the area of foundational cryptography
• Communication of results in the form of academic publications and presentations
• 20% of teaching for the department
