A Secure and Efficient Cluster-Based Authentication Scheme for Internet of Things (IoTs)

IPv6 over Low Power Wireless Personal Area Network (6LoWPAN) provides IP connectivity to the highly constrained nodes in Internet of Things (IoTs). 6LoWPAN allows with limited battery power and storage capacity carry datagrams lossy error-prone radio links offered by IEEE 802.15.4 standard, thus acting as an adoption layer between protocol network. The data link is based on AES (Advanced Encryption Standard), but standard lacks has omitted security privacy requirements at higher layers. sensor can join network without requiring authentication procedure. Therefore, from perspectives, vulnerable many attacks such replay attack, Man-in-the-Middle Impersonation Modification attack. This paper proposes a secure efficient cluster-based scheme (CBAS) for 6LoWPAN. In this approach, are organized into cluster communicate central through dedicated node. main objective CBAS provide authentic communication among nodes. To ensure low signaling overhead during registration, authentication, handover procedures, we also introduce lightweight de-registration, initial when node or group leave cluster. Our analysis shows that proposed approach protects against various attacks, including Identity Confidentiality Replay Man-in-the-middle simulation experiments show reduced registration delay 11%, handoff 32%, cost 37% compared SGMS (Secure Group Mobility Scheme) LAMS (Light-Wight Authentication & Scheme).
