Machine to Machine (M2M) communication is one of the most important parts of the Industrial Internet of Things (IIoT). In this field, a large number of devices and sensors communicate with each other without human intervention. To establish secure communication, IIoT devices must perform mutual authentication. Besides, not only well-known attacks but physical attacks are also expected in these systems. On the other hand, many IIoT devices (e.g., smart sensors) have limited processing power and memory. Therefore, many of the existing authentication protocols are not appropriate for these systems. To meet this issue, in this paper, a new authentication scheme is presented for M2M communication in IIoT by using lightweight cryptographic functions, such as XOR operation, one-way hash function, and Physically Unclonable Function (PUF). The security analysis demonstrates that the scheme is resistant to both physical attacks and several well-known attacks. Also, the performance evaluation shows that the protocol is efficient in terms of storage, communication, and computation costs. Conclusively, in comparison with the existing protocols, our proposed protocol is more applicable for IIoT.
