Trusted AI in Multiagent Systems: An Overview of Privacy and Security for Distributed Learning

Proceedings of the IEEE, Journal Year: 2023, Volume and Issue: 111(9), P. 1097 - 1132

Published: Sept. 1, 2023

Motivated by the advancing computational capacity of distributed end-user equipment (UE), as well increasing concerns about sharing private data, there has been considerable recent interest in machine learning (ML) and artificial intelligence (AI) that can be processed on UEs. Specifically, this paradigm, parts an ML process are outsourced to multiple Then, information is aggregated a certain level at central server, which turns centralized into one brings significant benefits. However, new paradigm raises risks terms privacy security issues. In article, we provide survey emerging from unique perspective exchange levels, defined according key steps process, i.e., consider following levels: 1) preprocessed data; 2) models; 3) extracted knowledge; 4) intermediate results. We explore analyze potential threats for each based overview current state-of-the-art attack mechanisms then discuss possible defense methods against such threats. Finally, complete providing outlook challenges directions future research critical area.

Trustworthy Federated Learning Against Malicious Attacks in Web 3.0

IEEE Transactions on Network Science and Engineering, Journal Year: 2024, Volume and Issue: 11(5), P. 3969 - 3982

Published: Jan. 5, 2024

In the era of Web 3.0, federated learning has emerged as a crucial technical method in resolving conflicts between data security and open sharing. However, is susceptible to various malicious behaviors, including inference attacks, poisoning free-riding attacks. These adversarial activities can lead privacy breaches, unavailability global models, unfair training processes. To tackle these challenges, we propose trustworthy scheme (TWFL) that resist above Specifically, firstly novel adaptive based on two-trapdoor homomorphic encryption encrypt gradients uploaded by users, thereby resisting Secondly, design confidence calculation contribution mechanisms attacks Finally, prove our through formal analysis, demonstrate experiments conducted MNIST FASHIONMNIST datasets TWFL achieves higher model accuracy 2%–3% compared traditional methods such Median Trim-mean. summary, not only variety but also ensure improved accuracy, which enough it solution suitable for 3.0 protection scenarios.
