The Chalmers CryptoTeam is recruiting! Join us as a PhD student and work on cutting-edge research in cryptography, in a dynamic and forward-thinking environment. 

About us 

The PhD student will join a world-leading research environment at the Chalmers Security & Privacy Lab as a member of the CryptoTeam. The Crypto Team currently has two faculty members and four PhD students with a focus on cryptographic primitives with advanced properties, protocols, provable security and foundations of cryptography.

The position is hosted by the Information Security (iSec) unit within the Department of Computer Science and Engineering—a joint department of Chalmers University of Technology and the University of Gothenburg with 300+ employees and a strong international profile.

About the research project  

The PhD student will join the CryptoTeam at Chalmers and will be supervised by Assistant Professor Elena Pagnin.

The research topic is “Consistency Protocols for Transparency Technologies”. This entails devising efficient ways to cryptographically ensure that a centralised system will deliver the same data to any user querying for any given label. For example, consistency guarantees that when public keys are distributed by a service provider (e.g., WhatsApp), all users will consistently get the same public key for any given user. The PhD student will focus on protocol design, security proofs, and integration into larger ecosystems.

This project defines and investigates evolving committee-based consistency protocols, a novel branch of consistency protocols for Transparency Logs (a generalization of a verifiable PKI). The goal is to prove security against a set of powerful and realistic adversaries using advanced cryptographic schemes and results from probability theory.
