The invention relates to a secure serial bus for automotive applications. A secure serial bus communication method and apparatus suitable for automotive applications are disclosed herein. An exemplary sensor IC includes a sensor controller that operates a transducer to obtain measurement data that can be formatted into data packets; a scrambler that masks each data packet by a scrambling operation before a data block is sent to the bus controller device via the serial bus, the scrambling operation having a secret configuration and/or a secret initial state; and an integrated circuit component that operates on the seed value to derive the secret configuration and/or the secret initial state.

    本发明题为“用于汽车应用的安全串行总线”。本文公开了适用于汽车应用的安全串行总线通信方法和设备。一种例示性传感器IC包括:传感器控制器,该传感器控制器操作换能器以获得能够格式化为数据分组的测量数据;加扰器,该加扰器在数据块经由串行总线发送到总线控制器设备之前通过加扰操作掩蔽每个数据分组,所述加扰操作具有秘密配置和/或秘密初始状态;以及集成电路部件,该集成电路部件对种子值进行操作以导出该秘密配置和/或该秘密初始状态。
