A Blockchain-based Resource Access Control and Sharing Mechanism in NFV
Anwei Dong, Xingwei Wang, Bo Yi, Qiang He · 2023
It is commonly known that sharing the infrastructure resource among different Virtual Network Function (VNF) can improve the resource utilization. However, conventional VNF sharing mechanisms tend to overlook the interests between VNF instances and infrastructure providers. In this context, this paper introduces a blockchain-based framework focusing on resource sharing and access control with profit priority during VNF instantiation. The designed framework plans the secure VNF resource sharing and access control process. Meanwhile, a resource sharing game model and a novel greedy matching algorithm are presented to optimize benefits for both VNF instances and infrastructure resource providers. Additionally, a blockchain-based access control mechanism is designed for secure key storage and fine-grained access control. The experimental results demonstrate the efficiency of the proposed mechanism.
