DOI: 10.1109/access.2022.3201648
Abstract: Physical layer covert channels exploit the characteristics of radio signals to convey secret messages while remaining inconspicuous within wireless channels. With specifically designed modulation schemes, covert channels effectively disguise secret messages as noise. Since the… read more here.

DOI: 10.1109/access.2022.3229124
Abstract: Federated learning (FL) goes beyond traditional, centralized machine learning by distributing model training among a large collection of edge clients. These clients cooperatively train a global, e.g., cloud-hosted, model without disclosing their local, private training… read more here.

DOI: 10.1109/lcsys.2020.3033059
Abstract: In this letter, using a control-theoretic approach, we present a covert channel technique, enabling a compromised networked controller to leak information to an eavesdropper who has access to the measurement channel. We demonstrate that this… read more here.

DOI: 10.3390/app11041641
Abstract: Network covert channels are increasingly used to endow malware with stealthy behaviors, for instance to exfiltrate data or to orchestrate nodes of a botnet in a cloaked manner. Unfortunately, the detection of such attacks is… read more here.
