📢Attending ACM SAC'26? Check out @ShengLiuKTH’s presentation on “DEFEND: Poisoned Model Detection and Malicious Client Exclusion Mechanism for Secure Federated Learning-based Road Condition Classification”, joint work w. @PanosPapadimitr (S2RAI: Safe, Secure and Robust AI Track)

This paper shows that FL-based intelligent transportation systems are vulnerable to targeted label-flipping attacks. We introduce DEFEND, a countermeasure that utilizes neuron-wise analysis to detect poisoned model and leverages adaptive rating to exclude malicious clients.
