Secured IoT Gateway For Smart Nation Applications

Security is a critical element for IoT deployment and it affects the adoption rate of smart nation applications. This paper presents a Cross-Layer Security Authentication Architecture that enhances the security of end-to-end communication for IoT nodes. The authentication architecture combines user-definable parameters, information from user identity, the physical, network and application layers to generate an encrypted unique authentication key that is embedded in each IoT device. Experimental tests were performed and field tests results for three smart nation applications, namely manufacturing, eHealth monitoring@Home and an integrated social and sensing solution using Vehicle-to-Anything (V2X) network are presented.
