Industrial Internet Data Sharing Scheme with Attribute-based Proxy Re-encryption in Cloud-chain Collaboration
摘要
Abstract
The industrial Internet is an application ecology of new generation information technology and industrial system in an all-round and deep integration.Through data sharing,it can realize the overall management and allocation of various resources in the industrial field.Aiming at the problem of privacy leakage in the process of industrial Internet data sharing,this paper proposes a cloud-chain collaborative attribute-based proxy re-encryption industrial Internet data sharing scheme,which stores massive industrial data ciphertext in the cloud,and solves the problem of computing and metadata ciphertext storage in the process of data security sharing on the blockchain.Construct a key generation algorithm that can avoid private key escrow by combining certificateless public key cryptography with ciphertext policy attribute-based encryption.Design a trust evaluation consensus algorithm to select nodes with high credibility as proxies in blockchain networks,solving the semi-trust problem of traditional proxy re-encryption.The security analysis shows that the proposed scheme satisfies keyword security and resistance to collusion attacks.The performance and simulation results show that the scheme in this paper has better functions and higher efficiency,and applicability for industrial Internet data sharing.关键词
