Our paper „Libertas: Backward Private Dynamic Searchable Symmetric Encryption Supporting Wildcards” got accepted for publication at DBSec 2022! In the paper, we propose our new encryption scheme Libertas which allows for secure search on encrypted dynamic databases. The novelty lies in the fact that Libertas supports wildcard search queries and meets, at the same time, the so-called „forward and backward privacy” notion, which increases security against file-injection attacks.
Welcome to the Safety-Security-Interaction Group!
The Safety-Security-Interaction group is concerned with the development of theoretically sound technologies for maintaining the security of IT systems in the context of safety-critical systems and the Internet of Things. The focus is on the development of security solutions that are tailored to the context-specific conditions and that take into account various types of user-interaction as well as the functional safety of the to-be-protected systems.
