Abstract:

Data sharing in the field of industrial Internet provides a powerful impetus for the vigorous development of industrial Internet by integrating management and flexible configuration of resources. However, there are single point of failure and data leakage problems in the current industrial Internet data sharing and storage process due to the adoption of single-cloud storage mode. This article proposes a multicloud collaborative data security sharing scheme with blockchain indexing. The blockchain-assisted multicloud storage model is constructed to enable indirect retrieval of industrial data through a federation chain. Enterprises on the alliance chain cannot directly access the industrial data stored in their respective private clouds for each other. To address the lack of trustworthiness of ciphertext retrieval, a tree-structured indexing method supporting keyword ciphertext retrieval is designed to realize efficient keyword token search. To prevent unfair trading behavior of data sharing participants, a fair trading contract is designed to overcome the disadvantage of dishonest execution of protocols by cloud servers. The security analysis shows that the scheme satisfies IND-CKA security. Simulation results show that the tree indexing approach constructed in this article has less time overhead compared to the traditional sequential indexing and other robust technique. And the efficiency advantage is more prominent when the number of keywords is huge.
