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.
