Wireless sensor networks (WSN) traditionally refer to a set of hundreds or thousands of devices with the ability to monitor certain physical parameters and send them cooperatively to a main node, the sink, which acts as an interface with the rest of the world. The diversity of services, applications, and devices applied in WSN has increased considerably in recent times, resulting in an increase of security requirements, threats, and weaknesses. Cryptographic primitives and algorithms and information security protocols are being proposed as solutions in many different environments, from the most classical, such as stream ciphers, authentication mechanisms or key distribution schemes, to the most recent ones, such as critical infrastructure protection, epidemic models for malware, jamming, and cyber-attack propagation, the application of artificial intelligence, etc.
This Special Issue focuses on cryptographic applications and information security protocols, algorithms, and systems for wireless sensor networks.
