摘要:

针对工业物联网(IIoT)中,工业设备将数据存储到云端,导致数据易被篡改且无法追踪恶意用户,引起恶性循环的问题,借助区块链的可溯源性和不可篡改性等特点,提出了一种基于区块链的双重可验证云存储方案。首先,使用同态加密技术加密数据并上传至云端,确保传输安全性,实现数据的隐私保护;其次,将聚合密文和上传者信息存储在区块链上,有效避免数据被非法用户篡改的风险,并能对恶意用户进行追溯,实现对云端数据完整性的双重验证;最后,进行安全性分析,证明所提方案比同类方案更加安全可靠。

Abstract:

In response to the problem that in the industrial Internet of things (IIoT), industrial equipment stored data in the cloud, causing data to be easily tampered with and unable to track malicious users, causing a vicious circle, with the help of the traceability and immutability of the blockchain, a dual verifiable cloud storage scheme based on the blockchain was proposed.Firstly, homomorphic encryption technology was used to encrypt data and upload it to the cloud , which ensured transmission security and realized data privacy protection.Secondly, the aggregated ciphertext and uploader information were stored on the blockchain, which could effectively avoid the risk of data being tampered with by illegal users, and could trace malicious users to achieve double verification of cloud data integrity.Finally, a safety analysis was carried out to prove that the proposed scheme is safer and more reliable than similar schemes.

Key words: blockchain, verifiable calculation, privacy protection, cloud storage
