Dear Colleagues,

Today, wireless sensing is the backbone of several IoT applications, ranging from environmental monitoring in smart cities to on-body sensors utilized in healthcare. While advances in wireless sensor technology facilitate higher data availability, lower energy requirements, and lower manufacturing costs, there is an ongoing demand to keep the level of security, privacy, and trust in wireless sensor networks (WSN) on par with classical IT systems.

Firstly, improvements in resilience shall push WSN applications toward critical infrastructure/disaster recovery, where continuous and reliable operation needs to be guaranteed. To this end, novel intrusion detection systems, robust medium access protocols, and anti-jamming techniques show potential as promising solutions.

Secondly, comprehensive vulnerability analyses on physical, network, and application layers are crucial to, e.g., unveil security design flaws or expose hidden vulnerabilities.

Thirdly, lightweight implementations of authentication, encryption, and secret key exchange are necessary to improve the confidentiality and authenticity of collected data. A potential way to approach resource conserving security features involves ingredients from physical layer security. Repurposing sensing technology to, e.g., generate true random numbers for cryptographic algorithms or perform tampering detection might help to reduce the computational and communication burden on the sensor node.

As the topic of this Special Issue touches upon multiple areas of wireless sensor technology, we humbly assume that the theme represents the scope of the Sensors journal as well as the interest of the readers. For instance, the wireless security topics deal with ways to improve data throughput under intentional/unintentional interference. Further, the physical layer security topics blend research agenda from, e.g., privacy and sensor data acquisition, which might be of interest to both security researchers and sensor technology experts.
