Review: Secure key management techniques in IoT-enabled wireless sensor networks.

with the hasty growth and extensive use of wireless sensor networks (WSNs), it is imperative to enhance the security for WSNs. The concept of the Internet of Things (IoT) is determined by growths of the Internet with the interconnectedness of diversified smart objects using dissimilar networking and communication technologies. Among countless basic networking technologies for the IoT, Wireless Sensor Network (WSN) technology has become an essential building block. IoT empowered sensor networks to afford a wide variety of application areas such as smart homes, smart healthcare, smart cities and various solutions for the manufacturing industry. The incorporation of WSNs in IoT will also generate newfangled security challenges for launching secure channels sandwiched between low power sensor nodes and Internet hosts. The key management is an effective way to protect WSNs from various malicious attacks. This will lead to numerous challenges in designing new key establishment and authentication protocols. This paper discusses about several KMS Taxonomies and surveys and recent KMS which are applicable for WSN. [ABSTRACT FROM AUTHOR]
