云辅助工业物联网中基于区块链的用户友好型数据检索和共享方案
Blockchain-based user-friendly data retrieval and sharing scheme in cloud-assisted industrial Internet of things
摘要
Abstract
To address the challenges of secure data retrieval and sharing in the industrial Internet of things(IIoT),as well as the vulnerability to offline keyword guessing attacks when using public-key encrypted indexes,a blockchain-based user-friendly data retrieval and sharing scheme was proposed suitable for IIoT.The scheme leveraged blockchain and proxy re-encryption to design a flexible and convenient dynamic data request mechanism,allowing data users to request authorization for data that they do not have access to,thereby obtaining it legally.Cloud servers performed pre-decryption of data,reducing the computational overhead on user devices.The scheme achieved secure multi-keyword search with fine-grained access control and user-defined search precision.A smart contract was used to generate tempo-rary query ID for users,and when returning searched results,additional users were randomly selected to forward the re-sults,preventing attackers from associating keywords with users.As a result,the scheme can resist offline keyword guessing attacks.Experimental results and security analysis show that the proposed scheme offers higher efficiency and is resistant to chosen-plaintext attacks,chosen-keyword attacks,and offline keyword guessing attacks.关键词
