Toward Secure Fault-Tolerant Wireless Sensor Communication: Challenges and Applications

The wireless sensor network (WSN) is gaining huge importance these days. It forms the backbone of IoT systems, a cutting-edge technology. As the applications are rapidly increasing, it is important to address the security concerns around this network. The fault-tolerant algorithms form an integral part of the wireless sensor distributed network. These algorithms make the wireless sensor network act as fault-tolerant, thus making the sensor readings more reliable. Even today, many sensor nodes are transmitting the data within the network in a wireless mode, with inappropriate security mechanisms in place. To overcome this gap, elliptic curve cryptography (ECC) and its variants are integrated with fault-tolerant sensor communications recently. In this study, we focus on presenting the challenges involved in implementing ECC-based secure sensor communication in the existing systems and the suitability of ECC-based secure communication for many real-time applications.
