Abstract: At training time, Federated Learning algorithms can be vulnerable to data and model poisoning attacks, where attackers can manipulate the parameters of the global model to produce indiscriminate or targeted errors when the model is deployed. In this talk we present, adaptive federated averaging, a technique for mitigating the effect of such attacks and detect the malicious participants trying to compromise a federated learning task, including a robust aggregation algorithm capable of ignoring malicious updates and a Hidden Markov Model to model the participants’ behaviour during training.

Abstract: Space-air-ground integrated networks (SAGINs) extend terrestrial network infrastructure to non-ter­restrial networks (NTNs), integrating satellite and unmanned aerial vehicle communications, high-altitude platforms, and space systems. These integrated networks can provide connectivity to remote locations, enhance service delivery, and support new ventures. NTN integration is an ambitious mission in 3GPP to extend the Internet to sky and outer space. Machine learning (ML) and artificial intelli­gence (AI) solutions are being explored to advance cooperative and autonomous behaviour, self-organisation, and optimisation in SAGINs with associated security challenges. In this talk, we will explore the security, intelligence, and programmable aspects of SAGIN.

Abstract: Federated learning provides a new way to use Machine Learning models as there is no need to exchange data. The only information exchange between the nodes regards the ML model’s parameters like the weights of a deep neural network. Although FL makes it possible to extract knowledge of training data without direct data exchange, transmitting the model updates could enable an attacker to infer private data. Our proposal for secure FL leverages the (Fully) Homomorphic Encryption (FHE) approach. FHE enables computation on encrypted data without the need for decryption, thus offering a robust solution for privacy-preserving FL. In this presentation we will examine the design considerations for integrating FHE into the Federated Learning model built for CONFIDENTIAL 6G use cases.

Abstract: The exponential growth in connected devices with Internet-of-Things (IoT) and next-generation wireless networks requires more advanced and dynamic spectrum access mechanisms. Blockchain-based approaches to Dynamic Spectrum Access (DSA) seem efficient and robust due to their inherited characteristics such as decentralization, immutability and transparency. However, conventional consensus mechanisms used in blockchain networks are expensive to be used due to the cost, processing and energy constraints. Moreover, none of the blockchain-based DSA systems can efficiently address spectrum violation (i.e., unauthorized access to the spectrum). To address these issues, we propose a newly tailored energy-efficient consensus mechanism called Distributed-Proof-of-Sense (DPoS) that is specially designed to enable DSA and detect spectrum violations. The proposed consensus algorithm motivates blockchain miners to perform spectrum sensing, which leads to the collection of a full spectrum of sensing data. An elliptic curve cryptography-based zero-knowledge proof is used as the core of the proposed mechanism. With the potential of blockchain and smart contracts, the proposed DSA system can provide service automation and real-time spectrum marketplace features as well.
