摘　　要：为解决工业互联网设备运行数据的可信存储问题,本文提出了基于IPFS的区块链数据可信存储系统。利用区块链技术的去中心化、可追溯与不可篡改等特性保证存储数据的真实可信。将源文件存入IPFS系统中,只将文件哈希摘要上链存储,在发挥了区块链优势的同时缓解了链上的数据存储压力。为进一步限制对数据的使用权限,系统内加入无证书密码体制对数据哈希摘要进行加解密操作。实验结果表明,本方案能实现工业互联网数据可信存储,且具有良好的系统性能。In order to solve the problem of trusted storage of industrial Internet equipment operating data, this paper proposes a trusted storage system for blockchain data based on IPFS. The decentralization, traceability and immutability of blockchain technology are used to ensure the authenticity and credibility of stored data. The source file is stored in the IPFS system, and only the hash summary of the file is stored on the chain, which relieves the data storage pressure on the chain while exerting the advantages of the blockchain. In order to further restrict the use authority of the data, a certificateless cryptographic system is added to the system to encrypt and decrypt the data hash digest. The experimental results show that this scheme can realize the trusted storage of industrial Internet data, and has good system performance.
