摘　　要：云存储广泛应用于数据外包、企业大规模数据存储等方面,但仍存在数据泄露、服务提供商不可信等风险,且操作记录不可追溯。对此,采用区块链和星际文件系统(InterPlanetaryFileSystem,IPFS)代替云存储,提出区块链上Paillier加密数据的安全存储及计算方法。实验结果和安全分析证明,所提出的方案在保护数据的防篡改性、可追溯性和隐私性的同时,实现了对加密数据的安全计算。Cloud storage has gained extensive adoption in areas such as data outsourcing and the management of large-scale enterprise data repositories.However,it continues to grapple with inherent risks including the potential for data breaches,the challenge of ensuring the trustworthiness of service providers,and the lack of a reliable mechanism for tracing operational records.In this regard,blockchain and InterPlanetary File System(IPFS)are used to replace cloud storage,and a secure storage and calculation method of Paillier encrypted data on blockchain is proposed.The experimental outcomes and comprehensive security analyses confirm that our scheme not only fortifies data against tampering,enhances traceability,and safeguards privacy but also enables secure processing of encrypted information.
