About

Marloes Venema

I am a postdoctoral researcher in the IT Security and Cryptography Group of Tibor Jager at the University of Wuppertal (since March 2023). Before this, I was a PhD student under the supervision of Greg Alpár in the Digital Security group at Radboud University Nijmegen. I defended my thesis, Attaining Basically Everything in Attribute-Based Encryption: Simplifying the Design of Practical Schemes via Pair Encodings, in September 2023. I also obtained a master's degree in Computing Science (Cyber Security) and a bachelor's degree in Mathematics at Radboud University.

My research focuses on practical and secure access control mechanisms for real-world applications. In particular, I design and analyze advanced cryptographic mechanisms, e.g., based on attribute-based encryption, that enable fine-grained access to sensitive information while providing strong security and privacy guarantees, e.g., by automating security analysis and implementation. By combining theoretical foundations with practical considerations, I aim to develop mechanisms that can be deployed in real-world settings such as healthcare, cloud infrastructures, citizen services, and content-delivery networks.

I have recently received an Emmy Noether grant from the DFG to establish my own independent research group at the University of Wuppertal (see MAPS-ABE).

Projects

MAPS-ABE · Emmy Noether Group

Funded by an Emmy Noether grant from the DFG, MAPS-ABE establishes my independent research group at the University of Wuppertal. The project develops modular approaches for simultaneously achieving practical and security properties in attribute-based encryption, with the long-term goal of enabling privacy-preserving access control (also to data that needs to be processed), including in the post-quantum setting.
