Aiming at the issue of fairness in cloud storage integrity audit
a Cloud Storage Integrity Auditing Model Based on Consortium Blockchains (CSACB) is proposed. First of all
the model describes the composition of audit consortium (AC) by a tree structure
and uses the layer certificate chain (LCC) to identify and control the members of the alliance. Second
variable cloud storage auditing is supported by a two-chain form of integrity auditing chain and dynamic operating chain. Finally
the fair dynamic operation audit model is constructed by using the smart contract (SC) and the data block label index mechanism
and the results of theoretical analysis and experimental show that the model has obvious advantages in terms of security and performance.
