PhD position in Privacy Preserving and Accountable Decentralized Protocols

 The IT University of Copenhagen invites highly motivated individuals to apply for a PhD position starting in 15 January 2023  or soon thereafter.

The IT University’s vision is to create and share knowledge that is profound and leads to groundbreaking information technology and services for the benefit of humanity. The Computer Science Department seeks to conduct research and education that are both foundational and have impact on industry and society.

Job description
In this project, we will investigate new techniques for constructing privacy preserving smart contracts that do not leak user data on the blockchain but still allow for public verification of their executions. While anonymous cryptocurrency systems such as Zcash solve the privacy issues of most current systems, they irrevocably hide all user activities, making it impossible to investigate illegal activities conducted in the system. Aiming at constructing regulation compliant protocols, we will investigate techniques for lawful auditing of user activities in privacy preserving blockchain applications.

The research in this project will focus on employing techniques from the areas of secure multiparty computation, zero knowledge and anonymous credentials to construct privacy preserving yet auditable cryptographic protocols for decentralized applications. More specifically, we will use these techniques to design and analyze provably secure multiparty computation with auditability guarantees and efficient integration with smart contract and cryptocurrency systems. We will also focus on improving the efficiency of such protocols aiming at practical applications.

The successful applicant should have a strong background in computer science or mathematics, with a focus on complexity theory, number theory, algebra and probability theory. Previous research experience in security and cryptography (specially in cryptographic protocols) is most welcome. Moreover, the successful candidate should be motivated and enthusiastic about theoretical research in cryptography.
