A method, an electronic control unit (ECU), and a secure automotive system are disclosed. The method includes the step of calculating encrypted values for one or more or all modules of the ECU. The ECUs are classified according to a network security assurance level (CAL). Further, the encrypted value is compared to a stored encrypted value. Thereafter, based on the CAL classification of the ECU, one of the following steps is performed: providing control to the one or more or all modules of the ECU when the encrypted value matches the stored encrypted value; and turning off the ECU in one of a current boot cycle or a subsequent boot cycle when the encrypted value does not match the stored encrypted value.

    本发明公开了一种方法、电子控制单元(ECU)和安全汽车系统。该方法包括计算ECU的一个或多个或所有模块的加密值的步骤。ECU根据网络安全保证等级(CAL)分类。进一步地,将加密值与存储的加密值进行比较。此后,基于ECU的CAL分类,执行以下步骤之一:当所述加密值与所述存储的加密值匹配时,向所述ECU的所述一个或多个或所有模块提供控制;以及当所述加密值与所述存储的加密值不匹配时,在当前引导周期或后续引导周期之一中关闭所述ECU。
