摘要
针对物联网燃气表终端远程升级过程中被恶意攻击、固件文件安全传输和可靠更新等问题,研究并设计了一种基于应用程序编程(IAP)技术的燃气表终端远程升级方案。提出采用双APP程序分区设计,升级时交替更新两个APP程序分区,确保不会发生不可回退的升级失败。在程序设计上对Bootloader程序采取轻量式设计,仅有程序跳转一个功能,其他与升级相关的功能全部放到APP程序中实现。整个升级操作由业务服务器、燃气表终端和升级服务器协同完成。测试结果表明,该系统方案能够安全、可靠地实现远程升级。
Based on Internet of things in the process of gas meter terminal remote upgrade by malicious attacks,reliable transmission and update the firmware file security problems,such as research and design a kind of gas meter terminal remote upgrade scheme based on in application programming(IAP)technology,put forward with double application(APP)partition design,upgrade alternately update two APP partition,ensure that won’t happen back,upgrade failure.In the program design,the Bootloader program is designed with light weight,with only one function of program jump,and other functions related to upgrade are all implemented in the APP program.The whole upgrade operation is completed by the business server,the gas meter terminal and the upgrade server.The test results show that the system scheme can realize remote upgrade safely and reliably.
