LAPE2D: Lightweight Authentication Protocol to Secure End and Edge Devices in Iot Framework

The Internet of Things (IoT) is omnipresent in every industry and has extended its footprint in various domains. This IoT device augmentation in today's smart world demands lightweight and secure authentication mechanisms for resource-constrained types of devices. This work proposed new authentication and key management schemes to equip these devices by leveraging lightweight cryptographic mechanisms. The proposed approach utilized various multi-device authentication scenarios such as end node to (edge) gateway, Gateway to Gateway and Node to Node through the gateway. In an IoT ecosystem, two end nodes have the same session key, which may be used for more secure communication. The robustness of the proposed mechanism is instantiated with the message exchange process of various scenarios and thorough cryptanalysis of the most common network intrusion attacks. Also, this proposed methodology provides more efficiency than existing works concerning communication overhead and computing complexity.
