With the popularity of smart home services, smart home devices are also increasing significantly. At the same time, security problems of smart home services are becoming more and more important. With the characteristics of non-tampering and multi-party consensus mechanism, Blockchain technology provides powerful capabilities in security protection. In this paper, we introduce the widely used permission Blockchain Fabric for smart home services. As the high requirements of performance, we firstly study the methods of performance optimization for Fabric. Then, a Fabric-based smart home security control system is designed. Based on this system, the smart home system is able to provide access control and security control for smart home devices. The experimental results show that the system works best when the number of concurrent registrations of smart home device is under 6000.
随着智能家居服务的普及，智能家居设备的数量也显著增加。与此同时，智能家居服务的安全问题也变得越来越重要。区块链技术具有不可篡改和多方共识机制的特点，为安全保护提供了强大的能力。在本文中，我们介绍了广泛应用于智能家居服务的许可区块链 Fabric。由于性能要求较高，我们首先研究了 Fabric 的性能优化方法。然后，设计了一个基于 Fabric 的智能家居安全控制系统。基于该系统，智能家居系统能够为智能家居设备提供访问控制和安全控制。实验结果表明，当智能家居设备的并发注册数量在 6000 以下时，系统性能最佳。
