An Enhanced Multifactor Authentication and Key Agreement Protocol in Industrial Internet of Things

Yiran Han, Hua Guo, Jianwei Liu +3 more

The Industrial Internet of Things (IIoT) is the application of the Internet of Things (IoT) in the industrial field. IIoT allows users to remotely access industrial equipment and the data in it, which also brings certain challenges to the security of industrial data. Authentication and key agreement protocols are very effective security technologies in the matter of protecting industrial data. There is a large amount of research work on authentication protocols in IIoT, but most of the protocols have security weaknesses. Recently, Rafique et al. proposed a multi-factor protocol in IIoT that can accomplish authentication and session key establishment through a gateway. Rafique et al. claimed that their protocol is secure, unfortunately, we carefully analyze the protocol of Rafique et al. and find some security flaws, i.e., it is vulnerable to insider attack and known session-specific temporary information (KSSTI) attack, and unable to provide forward security. We explore the factors of insecurity and propose an enhanced multi-factor secure authentication and key agreement protocol in IIoT. The new protocol improves the security of the protocol while using only symmetric cryptography, hash function, and XOR operation. Formal security analysis and informal security discussions demonstrate that the new protocol is resistant to a variety of known attacks. After performance analysis, our protocol has lower computational cost, and increases no significant communication cost, while providing more secure and robust properties.

Faster Authenticated Key Agreement With Perfect Forward Secrecy for Industrial Internet-of-Things

Zheng Yang, Jun He, Yangguang Tian +1 more

Industrial Internet-of-Things (IIoT) is the basis of Industry 4.0, which extends Internet connectivity beyond traditional computing devices like computers and smartphones to the physical world for improving efficiency and accuracy while reducing the production cost. However, there are tremendous security threats to IIoT, such as IIoT device hijacking and data leaks. Therefore, a lightweight authenticated key agreement (AKA) protocol is commonly applied to establish a session key for securing the communication between IIoT devices. To protect the previous session keys from being compromised, perfect forward secrecy (PFS) has been one of the most important security properties of AKA. In this article, we present an efficient PFS-enabled AKA protocol for IIoT systems, which is developed based on a new dynamic authentication credential (DAC) framework, without using any public-key cryptographic primitives. It is worth noting that our protocol is also faster than the state-of-the-art DAC-based AKA protocols with PFS. Moreover, we give the formal security result of the proposed protocol in the random oracle model.
