【Abstract】In recent years, traditional logistics systems are developing toward intelligence based on the Internet of Things (IoT). Sensing devices throughout the logistics network provide strong support for smart logistics. However, due to the insufficient local computing and storage resources of IoT devices, logistics records with sensitive information are generally stored in a centralized cloud center, which could easily cause privacy leakage. In this study, we propose a blockchain-assisted secure storage scheme for logistics data. To be specific, this scheme can be briefly divided into two parts. The first part involves data generation and aggregation, session establishing, records encryption and storage, wherein a blockchain network is used to assist the cloud server with data storage, and smart contracts are deployed to provide reliable storage interfaces. In the second part, an efficient consensus mechanism is introduced to improve the efficiency of the consensus process. Also, the stored records can be securely audited by leveraging the deployed blockchain network. Finally, we analyze the security and privacy properties of this scheme and evaluate its performance in terms of computation and communication overhead by developing an experimental platform. The experimental results indicate that the performance of our scheme is acceptable.

【摘要】近年来，传统的物流系统正朝着基于物联网（IoT）的智能化方向发展。遍布物流网络的传感设备为智慧物流提供了强有力的支持。然而，由于物联网设备本地计算和存储资源不足，带有敏感信息的物流记录一般都存储在集中的云中心，容易造成隐私泄露。在这项研究中，我们提出了一种区块链辅助的物流数据安全存储方案。具体来说，这个方案可以简单地分为两部分。第一部分涉及数据生成和聚合、会话建立、记录加密和存储，其中使用区块链网络辅助云服务器进行数据存储，并部署智能合约以提供可靠的存储接口。第二部分介绍了一种高效的共识机制，以提高共识过程的效率。此外，可以通过利用部署的区块链网络安全地审计存储的记录。最后，我们分析了该方案的安全性和隐私性，并通过开发实验平台评估了其在计算和通信开销方面的性能。实验结果表明我们的方案的性能是可以接受的。
