PHYSICAL LAYER SECURITY CHALLENGES

In cryptography, it is common practice to issue public challenges as a way to involve the wider community in the testing of cryptographic schemes. With these challenges, the ROBUST-6G project aims to bring this practice to the physical layer security community. We provide adversarial observations for various security scenarios, and ask researchers to break the security of the proposed schemes, according to specific, measurable target outcomes. By including measured experimental data in some of these challenges, we aim to determine whether practical imperfections due to wireless propagation or hardware impairments can be exploited to break theoretical guarantees.
