Outsourced databases need to compute query results over encrypted data.  This is challenging, since the operation needs to be efficient, but any side information can destroy the security of the encryption.  (Equi-)Joins are particularly challenging, since their operations are input data dependent.  I will present the most recent results on joins over encrypted data in the interactive setting, e.g. homomorphic encryption or multi-party computation, and the non-interactive setting, outsourced databases using functional encryption.

Florian Kerschbaum is an Associate Professor in the David R. Cheriton School of Computer Science at the University of Waterloo and has served as executive director of the Waterloo Cybersecurity and Privacy Institute since 2018. Prior to Waterloo, Florian worked as chief research expert at SAP in Karlsruhe (2005 – 2016) and as a software architect at Arxan Technologies in San Francisco (2002 – 2004).

Professor Kerschbaum holds a Ph.D. in computer science from the Karlsruhe Institute of Technology (2010) and a master’s degree from Purdue University (2001).

His interests lie in data security and privacy in data management, machine learning, and blockchains. He extend real-world systems with cryptographic security mechanisms to achieve (some) provable security guarantees. His work has been applied to products for databases, supply chain management and RFID tracking.
