SmartAgri‐IDQ: Quantum‐Resistant Identity‐Based Data Authentication Protocol for Smart Agriculture IoT

ABSTRACT The Internet of Things (IoT) has significantly transformed industries, including agriculture, by optimizing resources and enhancing monitoring. Smart agriculture IoT protocols utilize sensors for data transmission over the IoT network. Due to its open communication medium, it faces significant security challenges, including data authentication, etc. Current literature has various security methods to safeguard IoT‐enabled smart agriculture. However, it has been seen that such traditional systems are weak against the futuristic quantum computers. To safeguard smart agriculture IoT, we propose a quantum‐resistance identity‐based data authentication protocol and call it as SmartAgri‐IDQ. The security of the proposed authentication mechanism is based on the lattice hard assumptions such as small integer solution (SIS) or inhomogeneous SIS (ISIS) problems. The identity‐based cryptography (IBC) is used to avoid the overhead of certificate management and public‐key infrastructure (PKI). To validate the security of the proposed scheme, formal analysis has been done using the Random Oracle Model (ROM) and the Scyther tool, along with informal security analysis. To evaluate the efficiency, a performance and comparative analysis has been estimated based on storage, computation, and communication costs, which affirms the protocol's suitability in resource constraints smart agriculture IoT.
