基于区块链智能合约的异构服务器安全去重方法
Secure Deduplication Method with Blockchain-based Smart Contract for Heterogeneous Cloud Servers
摘要
Abstract
In the era of big data in response to the conflict between the reliability enhancement of user data in cloud server storage and the strategy for removing duplicate data,a heterogeneous server data security deduplication meth-od was proposed blockchain-based smart contracts.Leveraging the decentralized,tamper-proof,and publicly trans-parent characteristics of blockchain,as well as the automation capabilities of smart contracts,this method could a-chieve data storage security,reliability,and privacy protection.Specifically,the method combined secret sharing and blockchain smart contract technology to design a secure and efficient cloud storage data deduplication service.Moreover,by replacing the role of centralized third-party entities with blockchain and mitigating server heterogenei-ty through smart contract scripts,potential security risks were eliminated.Experimental results demonstrated that,under various scenarios with different file sizes and block quantities,the average computational overhead of this method was 65.42%to 115.77%lower than the comparative solutions,and the average storage overhead was 7.94%to 19.50%lower.Additionally,for varying numbers of heterogeneous storage servers,this method exhibi-ted significantly lower average computational and storage overhead,with reductions of 67.27%to 177.89%and 34.01%to 72.89%,respectively.Therefore,the proposed approach could outperform two existing blockchain-based deduplication method in terms of security,computational and storage efficiency.关键词
