Security Group at Chalmers with Christoph Egger as main
supervisor. The position is fully funded for 5 years and comes
with 20% teaching duties in the department. The Crypto Team
currently has 2 faculty members and 4 PhD students and is
embedded in the security group that captures a wide range of
topics.
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.
Applicants should have a strong interest in the mathematical
analysis of algorithms in general and cryptography in
particular. A master's degree in mathematics, computer science,
or a related discipline is required. The working language in the
department is English, and applicants are expected to be fluent
both in written and spoken English. Swedish courses are available
for interested students.
Applications are due March 10 and should be submitted via

## On the Topics
+ 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.
