智能家居门禁系统的安全控制方法

新兴的物联网技术为综合性智能家居测控系统的构建准备了条件，门禁系统作为智能家居的核心子系统之一，其安全控制的实现有助于提升智能家居的性能和用户体验。针对现有门禁系统存在的控制安全问题，提出了基于持卡人、门禁卡、读卡器三结合的认证机制、保密通信机制和时间戳机制的智能家居门禁系统安全控制方法，建立了近程刷卡控制和智能终端远程控制2种方式，实现对门禁系统通信数据的机密性和完整性保护，并阻止门禁控制指令被截取和滥用，构建了相应的物理仿真系统。测试结果表明，基于物联网技术的智能家居门禁系统在提升使用方便性的同时，所蕴含的安全控制方法有助于增强智能家居门禁系统控制的安全，验证了所提出方案的有效性和实用性。

Secure control methods of the entrance guard system for smart home

The emerging internet of things technology prepares conditions for building a comprehensive smart home, and the entrance guard system is one of the core subsystem of smart home, whose implementation in safety control helps improve the performance of smart home and user experience. Aiming at the secure control problem of the existing entrance guard system, one secure control method of entrance guard system for smart home is proposed, which is based on such mechanisms as authentication among cardholder, entrance card and card reader, secret communication and timestamp. The paper also established two ways including short-range charge control and intelligent terminal remote control, so as to realize the confidentiality and integrity protection of communication data of the entrance guard system, and prevent control instructions from being intercepted and abused, and the corresponding physical simulation system is also set up. The test result shows that the entrance guard system of smart home based on the internet of things technology improves convenience in use, at the same time, the in-built secure control methods are helpful to strengthen the security of control of entrance guard system in smart home, thus prove the effectiveness and practicability of the proposed scheme.
