Survey on Federated Learning Threats: concepts, taxonomy on attacks and defences, experimental study and challenges Rodríguez Barroso, Nuria Jiménez López, Daniel Luzón García, María Victoria Herrera Triguero, Francisco Martínez Cámara, Eugenio Federated learning Adversarial attacks Privacy attacks Defences Federated learning is a machine learning paradigm that emerges as a solution to the privacy-preservation demands in artificial intelligence. As machine learning, federated learning is threatened by adversarial attacks against the integrity of the learning model and the privacy of data via a distributed approach to tackle local and global learning. This weak point is exacerbated by the inaccessibility of data in federated learning, which makes harder the protection against adversarial attacks and evidences the need to furtherance the research on defence methods to make federated learning a real solution for safeguarding data privacy. In this paper, we present an extensive review of the threats of federated learning, as well as as their corresponding countermeasures, attacks versus defences. This survey provides a taxonomy of adversarial attacks and a taxonomy of defence methods that depict a general picture of this vulnerability of federated learning and how to overcome it. Likewise, we expound guidelines for selecting the most adequate defence method according to the category of the adversarial attack. Besides, we carry out an extensive experimental study from which we draw further conclusions about the behaviour of attacks and defences and the guidelines for selecting the most adequate defence method according to the category of the adversarial attack. This study is finished leading to meditated learned lessons and challenges. 2022-12-22T07:47:15Z 2022-12-22T07:47:15Z 2022-01-20 journal article Published version: Nuria Rodríguez-Barroso...
