Two attacks (with countermeasures) got accepted at ACNS 2022, the 20th International Conference on Applied Cryptography and Network Security!
The first attack concerns secure conjunctive keyword search schemes. Those are encryption schemes that allow for searching on encrypted data. We specifically looked at schemes that allow for conjunctive keyword search queries.
The second attack concerns industrial control systems. We show how an attacker with limited knowledge on the targeted system can automatically identify sensors that, through targeted manipulation with a single try, can lead to a complete shutdown of the entire system.
