摘要
针对现有物联网网关的异构性终端接入需求和数据传输的安全问题,本文设计了一种同时支持Wi-Fi、蓝牙和ZigBee等无线连接方式并且采用SM4国密算法加密传输数据的安全物联网网关。网关硬件设计方面,采用三星Exynos4412开发板,板载Wi-Fi/蓝牙二合一芯片RTL8723U,另外通过串口外接ZigBee芯片ZA2530-2591;网关软件设计方面,通过向主控芯片烧入同时支持三种连接方式的Java程序,结合SM4国密算法,满足了终端向网关的多方式连接请求和数据安全传输需求。最后的测试表明,网关的总平均连接失败率为0.4知,总平均连接时间为7.50ms,远低于CCSA规定的标准。
To meet the heterogeneous terminal access requirements of the existing Internet of Things gateway and to ensure the data transmission security,a secure Internet of Things gateway which supports Wi-Fi,Bluetooth and ZigBee wireless connection modes and adopts the SM4 national secret algorithm to encrypt data transmission is designed in this paper.In terms of hardware design,Samsung Exynos4412 development board and onboard Wi-Fi/Bluetooth two-in-one chip RTL8723U are adopted,and ZigBee chip ZA2530-2591 is connected externally through serial port.In the aspect of software design,the multi-mode connection request from terminal to gateway and the demand of data transmission security are satisfied by typing JAVA program that supports three connection modes simultaneously to the main control chip and combining the SM4 national secret algorithm.The final test results show that grand mean connection failure rate of the gateway is 0.4‰and grand mean connection time is 7.50ms,which are well below the standards set by the CCSA.
