PASS: Parameters Audit-based Secure and Fair Federated Learning Scheme against Free Rider. (arXiv:2207.07292v1 [cs.CR])

Federated Learning (FL) as a secure distributed learning frame gains interest
in Internet of Things (IoT) due to its capability of protecting private data of
participants. However, traditional FL systems are vulnerable to attacks such as
Free-Rider (FR) attack, which causes not only unfairness but also privacy
leakage and inferior performance to FL systems. The existing defense mechanisms
