Low-Power Wide-Area Networks (LPWANs) are an emerging Internet-of-Things (IoT)
paradigm, which caters to large-scale and long-term sensory data collection demand …

The vast demand for diverse applications raises new networking challenges, which have
encouraged the development of a new paradigm of Internet of Things (IoT), eg, LoRa. LoRa …

Reproducibility is crucial to the advancement of science; it strengthens confidence in
seemingly contradictory results and expands the boundaries of known discoveries …

Hidden cameras in sensitive locations have become an increasing threat to personal privacy
all over the world. Because the camera is small and camouflaged, it is difficult to detect the …

In this paper, first, a broad overview of existing covert channel communication-based
security attacks is provided. Such covert channels establish a communication link between …

As the popularity of graphics processing units (GPUs) grows rapidly in recent years, it
becomes very critical to study and understand the security implications imposed by them. In …

This article presents a new attack allowing attackers to exfiltrate data from isolated, air-
gapped computers via Wi-Fi frequencies. We show that malware in a compromised air …

In this article, we introduce a new covert channel that enables attackers to leak data
acoustically from highly secured, air-gapped and audio-gapped systems. The proposed …

Air-gapped systems are isolated from the Internet due to the sensitive information they
handle. This paper introduces a covert channel attack that leaks sensitive information over …

LoRa has emerged as one of the promising long-range and low-power wireless
communication technologies for Internet of Things (IoT). With the massive deployment of …
