快科技8月24日消息，工信部组织全国汽车标准化技术委员会完成了《汽车密码技术要求》强制性国家标准的制修订工作，征求意见稿已于8月21日公开发布，向社会各界征求意见，截止日期为2026年10月20日。    (ECNS) -- The first phase of the middle route of China's South-to-North Water Diversion Project had transferred more than 80 billion cubic meters of water to northern China as of Friday, directly benefiting nearly 118 million people, according to the Changjiang Water Resources Commission.     The water comes mainly from Danjiangkou Reservoir, where managers balance reservoir inflows, local demand in the Hanjiang River basin, northbound supplies, and downstream ecological needs.        This summer, after forecasts pointed to below-normal rainfall, authorities adjusted reservoir operations to retain about 1.5 billion cubic meters more water as a buffer against possible drought.    Technology is playing a growing role in monitoring water quality.    An AI-powered floating platform works alongside satellites, drones, and ground monitoring stations, feeding data into a digital twin of Danjiangkou Reservoir that tracks water quality, simulates flood scenarios, and supports emergency planning.    At Danjiangkou Reservoir, the core water source for the middle route, an autonomous vessel collects samples from different depths to monitor algae.    Using AI-powered microscopy, the floating station identifies microorganisms quickly and tracks algal activity, giving early warning of blooms.    The vessel is part of an integrated satellite, aerial, surface, and structural monitoring network that combines remote sensing, drones, ground-based stations, and sensors embedded in the dam.    By fusing multi-source data in real time, the system has shifted water monitoring "from isolated points to full-area coverage," said Cui Dongdong, deputy director of the technology development department at a company under the Yangtze River Water Resources Commission of the Ministry of Water Resources.    With the digital platform, a regulation plan that once took days to produce can now be generated in seconds.    The platform runs more than 15 professional models covering flood routing, pollutant dispersion, and dam structure simulation.    The 1,432-kilometer middle route canal carries water across the Yangtze, Huai, Yellow, and Hai river basins before it reaches households in the north.    Water quality has also improved, and the nationally protected "crystal jellyfish," known as the "giant panda of the water," is now sighted frequently in the reservoir, an indicator of excellent conditions.     (By Helen Mo, intern Yang Hongran)                    。标准规定了汽车密码应用技术要求及同一型式判定，并描述了相应的试验方法。

二 | 其中最核心的要求之一是安全启动密码应用，车辆需通过密码技术确保在上电或重启过程中加载的软件组件真实、完整、可信，防止固件、引导程序、操作系统或关键应用软件被非法篡改、替换或伪造后运行。换言之，车辆每次上电启动时，软件系统都要先过一道“密码验真”关卡，逐级校验各层启动组件的合法性，任何一层被篡改都将被拦截。测试方法也相当硬核，测试人员需依次尝试替换固件、引导程序、操作系统、关键应用软件等启动组件镜像，上电启动车辆，检测车辆系统是否具备逐级安全启动校验流程。该标准还涵盖车载软件升级（OTA）场景，要求车辆使用车载软件升级系统进行软件升级时，应采用密码技术对升级包进行真实性和完整性验证，确保升级过程中不被注入恶意代码。标准适用于指导、规范汽车整车及零部件产品密码应用的设计、开发、测试验证，涵盖总体框架、通用要求、安全要求等内容。据悉，此次强制性国标的出台，意味着汽车软件安全将从“企业自律”迈向“强制合规”，未来所有在中国市场销售的车型都必须满足密码应用技术要求。
