A Secure Lightweight Mutual Authentication Scheme in Social Industrial IoT Environment

The Social Industrial Internet of Things (SIIoT) is a new paradigm that integrates social networking features into the Industrial IoT (IIoT) environment to enforce efficient and effective service discovery and collaboration between smart IoT objects in a friendly and scalable way. Therefore, in such environment, the establishment of secure and trust communication scheme is a crucial need between peer IoT devices having similar social profiles. In addition, the limited resource constrained IoT devices are unable to deal with huge computational overheads. To address these issues, we propose a novel solution offering secure Fog-based Social Industrial IoT (Fog-SIIoT) scheme. Fog-SIIoT guarantees mutual authentication, anonymity, and secure communication through a trust key agreement between social smart things. The proposed scheme is suitable for the social resource constrained IIoT as it only uses hash function, bitwise XOR operation, and symmetric cryptography. Comparing to correlative schemes, our solution presents many advantages in terms of security aspects, efficiency, social-awareness, and reduced computation overheads. Besides, the security analysis indicates that our scheme can withstand many known attacks.
