A new three-factor authentication scheme using Chebyshev chaotic map for peer-to-peer Industrial Internet of Things

Abstract

The Industrial Internet of Things (IIoT) is an emerging technology for smart manufacturing and productivity improvement. Due to the increasing complexity of manufacturing, devices with smart industrial sensors from several domains work together on the same job, raising serious security and privacy concerns about peer-to-peer (P2P) communication. Specifically, P2P secure communication should be focused on when it comes to high efficiency and security of information exchange between two industrial sensors. However, none of the existing schemes can resist physical attacks towards industrial sensors. To resolve the problem, we propose a new three-factor authentication and key agreement scheme named NTFAK for P2P IIoT communication using Physical Unclonable Functions (PUF) and Chebyshev chaotic mapping, where PUF is used to replace the smart card factor in the traditional schemes. The unclonable property of PUF and its ability to securely identify a device by challenge-response can provide safety to physical attacks. Besides, the use of the Chebyshev chaotic map also can provide high computational efficiency while ensuring better security. The proposed scheme enables secure communication between any two industrial sensors, which can resist physical attacks and offer a smaller key size, faster computation, and higher efficiency for IIoT. The security of our scheme is formally proved by the random oracle model, and security properties are discussed to show our scheme resists various attacks. Moreover, experiments were implemented to prove the efficiency of our scheme. Specifically, the results show that NTFAK can improve the computation and communication overheads by 36.6% and 17.5% at least, compared to existing schemes, while also ensure a minimum time reduction of 30.4% in delay time. In terms of security and functionality features, NTFAK satisfies the proposed 14 properties, outperforming existing solutions.
