Light-SAE: A lightweight authentication protocol for large-scale IoT environments made with constrained devices

Due to the increasing demand for Internet of Things (IoT) applications with sensitive data, use encryption on constrained devices is crucial protecting and ensuring privacy security. The used in such have limited computational power, memory, energy resources, making them vulnerable attacks that exploit these limitations. Lightweight cryptography has been growing fast recent years aiming circumvent lack security types devices. We propose a modular solution capitalizes strengths lightweight offer an approach can be easily adapted meet needs private wireless sensor networks. designed work multi-hop communication networks, where Nodes out range Gateway part network, offering same level Node has. To further enhance lifetime our incorporates key renewal mechanism supports signature schemes integrity. Additionally, it distributed achieve high levels scalability. Experimental results show using top standard protocols does not introduce significant overhead terms performance.
