Treffer: Simple, secure and lightweight authentication protocol with session-key generation for IIoT device in IIoT networks.

Device authentication is essential for protecting IIoT networks due to the industrial internet of things (IIoT) rise in connected devices. This work presents a novel protocol for IIoT device authentication using XOR and hash functions, two simple cryptographic techniques. Our protocol makes use of authentication and session key generation to increase the security of IIoT devices in IIoT networks. In our proposed protocol, IIoT devices send a message to a server requesting authentication, and the server responds with session keys. In order to maintain a secure connection, the IIoT device refreshes the session key and stores it for use in upcoming communications. We used the AVISPA (automated validation of internet security protocols and applications) and ProVerif tools to assess our proposed protocol. The outcomes of our proposed protocol demonstrate that this protocol provides a low-overhead, secure, and effective mechanism for IIoT device authentication. Our proposed protocol uses the least amount of energy, making it simple to implement in a real-time context. [ABSTRACT FROM AUTHOR]
