Soft-Trust Based Architecture for NextG IIoT/IoET Security, Authentication and Authorization
2023 IEEE Texas Power and Energy Conference (TPEC)(2023)
摘要
One of the biggest challenges in scalable deployments of massive machine type communication (mMTC) is the efficient, scalable and low-delay security and authentication solutions. MMTC involves Industrial Internet of Things (IIoT) and Internet of Energy Things (IoET) in 5G/6G and Next Generation (NextG) Power Systems. Criticality of this challenge is amplified when considering characteristic limitations of typical IIoT & IoET devices and inherent lack of robust built-in security features. Scalable solutions for IIoT dynamic authentication and authorization could address many of the concerns. In this work, we review and propose an architecture for trust management of IIoT/IoET devices in NextG Systems using suitable trust tools and frameworks such as Blockchain. The proposed architecture adopts a two-tier hierarchical Blockchain-based consensus. To support scalability, we examine the benefits of utilizing a directed acyclic graph (DAG) data structure on the Blockchain.
