The invention discloses a whole vehicle ECU upgrade system and method based on OTA upgrade package encryption, the system comprises an OTA platform, an OTA server, an OTA vehicle end, a TSP vehicle networking platform and ECU electronic control unit equipment, an ECU equipment side uploads an upgrade package to the OTA platform, the OTA platform calculates an upgrade package file and signs and encrypts the upgrade package file, and then a corresponding upgrade strategy is created and an upgrade task is issued on the OTA platform. The OTA platform can terminate and recover an upgrade strategy at any time, the ECU end adopts signature authentication and an OTA background server to perform identity authentication and downloads an upgrade package to the local, an upgrade result is fed back to the OTA platform in the form of encrypted data flow, and the OTA platform analyzes a terminal instruction to obtain the upgrade result and displays the upgrade result on the OTA platform. According to the invention, while the OTA safety of the ECU of the whole vehicle is ensured, a trusted chip is not needed, and the hardware cost of OTA upgrading is reduced.
本发明公开了一种基于OTA升级包加密的整车ECU升级系统及方法,包括OTA平台、OTA服务器、OTA车端、TSP车联网平台和ECU电子控制单元设备,由ECU设备方将升级包上传至OTA平台,OTA平台计算升级包文件并进行签名、加密,然后在OTA平台创建对应的升级策略,发布升级任务。OTA平台可随时对升级策略进行终止、恢复,ECU端采用签名认证与OTA后台服务器进行身份认证并将升级包下载至本地,升级结果以加密数据流的形式反馈至OTA平台,OTA平台对终端指令进行解析,得到升级结果展示在OTA平台。本发明在保障整车ECU的OTA安全的同时,无需可信芯片,降低了OTA升级的硬件成本。
