摘　　要：目前,通过工业物联网不同类型的工业设备实现集群交互,打破了数据孤岛,使得数据不再是独立的,但在这种情况下,数据的传输伴随着数据泄露这一安全问题。此外,工业物联网还表现出需要去中心化、可追溯等特点。为了解决这一问题,本文提出了一个在区块链架构下的基于椭圆曲线加密算法的工业物联网数据隐私保护方案。在方案中,数据接收者和数据发送者之间的数据通过一次性密码进行加密。同时,方案中的密钥传输、密文传输等均由智能合约进行管理,加解密过程均在本地操作,减少智能合约的计算消耗。最后,方案经过仿真及安全性分析,确保方案能实现数据隐私保护。At present, the cluster interaction of different types of industrial equipments through the Industrial Internet of Things breaks the data silos, so that the data is no longer independent, but in this case, the transmission of data is accompanied by the security problem of data leakage. In addition, industrial objects networking also needs features such as decentralization and traceability. In order to solve this problem, this paper proposes an industrial IoT data privacy protection scheme based on elliptic curve encryption algorithm under the blockchain architecture. In the scheme, the data between the data receiver and the data sender is encrypted by a one-time password. Meanwhile, the key transmission and ciphertext transmission in the scheme are managed by smart contracts, and the encryption and decryption processes are operated locally, reducing the computational consumption of smart contracts. Thereafter, through simulation and security analysis, it is ensured that the scheme can achieve data privacy protection.
