Group Sessions
Working groups and room arrangement
ASK 2026 features working-group discussions in the afternoons. We aim to form several small groups, each focused on a specific topic, to foster collaboration and produce tangible research progress.
The following sub-topics are simply intended as a framework to help ensure everyone is paired with fellow researchers sharing similar interests. We recognize that research in symmetric cryptography often crosses these boundaries.
