International Association
for Cryptologic Research

As AI agents start acting in groups, delegating, negotiating, and relying on each other's inputs and outputs, the security assumptions behind single-model systems stop holding. This project develops principled and scalable foundations for trustworthy collaboration between AI agents, sitting at the intersection of AI and cybersecurity. It is funded by the Swedish Foundation for Strategic Research (SSF) under a programme building research ties between Sweden and Taiwan, including opportunities for research visits among the participants.

We are looking for a dedicated PhD student to strengthen our research in trustworthy multi-agent AI systems. Example research topics include evaluating the robustness of multi-agent systems under adversarial manipulation, designing secure and privacy-preserving multi-agent collaborative mechanisms, and verifiable decision-making under uncertainty and adversarial influence. You will be based in the RISE office at Kista, Stockholm for 4 years, and you will be enrolled as a doctoral student at a Swedish University. PhD education also involves participation in relevant university courses.

We are looking for a PhD student to work on FPGA implementation of fully homomorphic encryption schemes.

About you

Undergrad and master degrees in Computer Science, Mathematics or related topics. Some experience with hardware implementation is required. If you know very well FPGA, but don't know much about crypto, that is not a problem, as long as you are wiling to learn it. You are expected to be proactive and to have some level of independence.

About us:

We are one of the main universities of Brazil, located in a beautiful campus in a calm neighborhood. There are many cultural activities nearby, technological centers including companies like Samsung and LG, parks and natural areas. Also, traveling to other regions of Brazil is very easy (there is an airport in Campinas).

The project concerns information- and coding-theoretic methods for analysing and improving the resilience and efficiency of federated machine learning methods in settings where communication bandwidth is limited and nodes are unreliable.

The project is funded by KTH as part of a joint initiative aimed at strengthening relations between KTH and selected partner universities. The project is carried out in collaboration with the Technical University of Denmark (DTU) in Lyngby, Denmark. The doctoral student will be supervised by two supervisors at KTH and two supervisors at DTU. Mobility is a requirement for the doctoral student; the student is expected to spend a total of at least one year at DTU. However, this period does not need to be continuous and will be planned in consultation between the doctoral student and the supervisors.

Supervision: Professor Ragnar Thobaben and Professor Mikael Skoglund (KTH) as well as Professor Søren Forchhammer and Assistant Professor Stanislav Kruglik at DTU. Decision will be made upon admission.

Artificial intelligence now supports high-stakes decisions in cybersecurity, finance, healthcare, and public services, where accuracy alone is not enough. Such systems must also respect legal, regulatory, contractual, or organisational limits on their use and disclosures. Enforcing these limits is difficult when the data, model, and rules belong to different parties, none of whom can simply hand over what they hold. Privacy-preserving AI protects data and models but not rules, while conventional guardrails inspect information in plaintext and offer weak formal assurance.

This PhD project asks how to build useful AI services that enforce such constraints while protecting sensitive information.

Key research questions include:

• What should compliance mean formally when no party sees the whole system?
• How can enforcement be made verifiable rather than merely trusted?
• What are the practical costs of providing these guarantees?

The research spans cryptography, privacy-enhancing technologies, and trustworthy AI. It will involve stating requirements precisely, designing methods that meet them, analysing their guarantees, and building prototypes to assess their practical performance.

Who should apply? The studentship covers fees at the (UK) Home rate. Home fee status includes UK and Irish nationals, and those with settled or pre-settled status or indefinite leave to remain who meet the residency criteria. International applicants must cover the difference between Home and International fees. Applicants should hold, or expect to obtain, a strong degree in computer science, cybersecurity, mathematics, or a related subject. Experience with cryptography, machine learning, or systems implementation is valuable, as are strong programming skills and an interest in both proofs and prototypes.

Research environment: The successful candidate will join the Cryptography and AI Security Lab at Newcastle University.
