    Abstract: A method of authenticating an automotive device connected to an engine control system that stores an authentication code in memory of the automotive device that is generated by an encryption algorithm using an identification code of the automotive device as a seed value. The engine controller determines a verification code using a complementary encryption algorithm that also uses the identification code received from the automotive device as a seed value. The engine controller compares the authentication code to the verification code, and indicates that the automotive device is not authentic if the authentication code does not correspond to the verification code. Advantageously, authenticating the automotive device will be done autonomously by the engine controller without prompting by a technician using special equipment such as a laptop computer.

    Abstract translation: 一种认证连接到发动机控制系统的汽车装置的方法,该发动机控制系统将认证码存储在汽车装置的存储器中,所述存储器是使用汽车装置的识别码作为种子值的加密算法产生的。 发动机控制器使用补充加密算法确定验证码,该算法还使用从汽车设备接收的识别码作为种子值。 发动机控制器将验证码与验证码进行比较,并且如果认证码与验证码不对应,则指示汽车设备不可信。 有利地,认证汽车设备将由发动机控制器自主进行,而不需要技术人员使用诸如膝上型计算机的特殊设备的提示。
