An Enhanced Hybrid Algorithm for Wireless Sensor Networks Security in the Internet of Things

Abstract

The Internet of Things (IoT) is an exciting future technology that promises to connect tons of devices through the internet. As the number of people connecting to the internet increases, it is expected that communication will produce mountains of data. Wireless Sensor Networks (WSNs) are now used by IoT to collect, monitor, and transmit data and confidential information through wireless networks using sensor nodes. There are numerous challenges that WSNs encounter caused by attackers with unauthorized access and data security. Especially in the context of IoT, where small embedded devices such as sensor nodes with poor computational capabilities are expected to connect to a larger network. Thus, WSNs are prone to a variety of attacks. Furthermore, implementing security is time-consuming and selective, as traditional security algorithms degrade the security of data in transits due to computational complexity and inherent delays experienced during algorithm execution. As a result, this research paper presents an encryption algorithm that integrates the Secure IoT (SIT) algorithm with the Security Protocols for Sensor Networks (SPINS) security protocol to develop a Lightweight Security Algorithm (LSA) to overcome data security issues while minimizing the level of attacks and power consumption in WSNs without compromising the performance.
