摘要： 随着大数据时代的来临,如何在开放、动态、难控的互联网中实现安全可信的数据共享已成为亟待解决的问题。区块链技术以其去中心化、不可篡改等特性,为构建数据可信共享机制提供了技术思路。为此,提出了一种基于联盟区块链的数据可信共享方案。首先,定义了一种基于联盟区块链的数据架构范式,并通过标准化注册流程,高效整合异源、异域、异构的数据资源;同时,设计并实现了数据可信追溯机制,通过数据共享全过程链上留痕的方式,来保证数据需求方、计算节点和数据提供方之间数据流动的安全性和完整性;此外,设计了一种数据处理即服务(Data Processing-as-a-Service,DPaaS)的数据可信共享框架,来支撑数据共享的关键步骤,即需求匹配、数据共享、满意度评价,以应对数据共享过程中的信任挑战。实验结果表明,与传统数据共享方案相比,随着数据集的增大,拟议方案的额外时间占比可降至数据共享总时间开销的30%以内;智能合约查询平均时延能够稳定在0.12~0.2 s,智能合约写入平均时延能够稳定在3~5 s。

Abstract: With the advent of the big data era,securing and trustworthily sharing data on an open,dynamic,and difficult-to-control Internet has become an urgent problem to solve.Blockchain can reasonably be introduced into the trust resolution mechanism for data sharing,leveraging its significant advantages in decentralization and tamper resistance.Thus,a data trusted sharing scheme based on consortium blockchain is proposed.Firstly,a consortium blockchain-based data architecture is defined to solve the problem of heterogeneous data sources and domains.Through standardized registration processes,data resources are integra-ted efficiently.Secondly,a trusted data traceability mechanism is designed and implemented to ensure the security and integrity of data flow among data requesters,compute nodes,and data providers by leaving the traces of the data sharing process on consor-tium blockchain.In addition,a data-processing-as-a-service data sharing framework is developed to support key steps in data sharing:demand matching,data sharing,and satisfaction evaluation,addressing trust challenges during the data sharing process.The experimental results show that,compared with traditional data sharing schemes,the proportion of additional time in the proposed scheme decreases to less than 30% of the total time cost as the dataset size increases.Additionally,the average latency for querying smart contracts remains stable between 0.12 and 0.2 seconds,while the average latency for writing smart contracts stays consistent at 3 to 5 seconds.
