Abstract

There is a growing concern about the complete lifecycle security of data in Internet of Things (IoT). This may cause privacy and trust problems for users regarding data sources, data storage, and access control for data sharing. Blockchain is a valuable solution to the above problems through distributed ledger technology, and it has been widely applied in various fields such as public services, finance, and IoT. However, the data in IoT are characterized by a large quantity, large capacity, and timely response, and existing blockchain systems only partially resolve them for data security and performance. We propose DSChain for IoT data security to address the challenges mentioned above. Our system uses a certificateless signature to ensure a trusted data source and public auditing to ensure the integrity of stored data while using ciphertext-policy attribute-based encryption to control access to shared data. Moreover, we propose a packaging mechanism based on the Merkle Hash Tree that effectively improves system performance. We implement the DSChain and provide a detailed analysis of performance and security. The experimental results indicate that DSChain can achieve approximately 1035 transactions per second on a single peer and is scalable.

DSChain：实现物联网数据全生命周期安全的区块链系统

人们越来越关注物联网（IoT）数据整个生命周期的安全性。这可能会在数据源、数据存储和数据共享访问控制方面给用户带来隐私和信任问题。区块链是通过分布式账本技术解决上述问题的重要方案，目前已广泛应用于公共服务、金融、物联网等多个领域。然而，物联网中的数据具有数量大、容量大、响应及时等特点，现有的区块链系统只能部分解决数据安全和性能问题。针对上述挑战，我们提出了用于物联网数据安全的 DSChain。我们的系统使用无证书签名来确保数据来源可信，并使用公共审计来确保存储数据的完整性，同时使用基于密文策略属性的加密来控制对共享数据的访问。此外，我们还提出了一种基于梅克尔哈希树的打包机制，可有效提高系统性能。我们实现了 DSChain，并对其性能和安全性进行了详细分析。实验结果表明，DSChain 可在单个对等节点上实现每秒约 1035 次交易，并且具有可扩展性。
