SECURE BOOT OF VEHICULAR PROCESSORS

Techniques for securely booting processors in a vehicle are described. An apparatus comprises a circuit coupled to one or more processors of a vehicle and managing a secure boot process for the processors. The circuit receives an indication that the vehicle has been powered on and sends, to a network server, a request for boot files for the processors of the vehicle. In response, the circuit receives, from the server, most recent versions of boot files respectively corresponding to the processors, wherein each boot file includes a digital signature of a trusted authority. In response to obtaining the most recent versions of the boot files, the circuit sequentially boots the processors using the respective boot files, wherein each processor executes a corresponding boot file upon verifyingauthenticity of the digital signature in the boot file using a corresponding class authentication key. 本发明描述了用于安全地启动交通工具中的处理器的技术。设备包括连接至交通工具的一个或多个处理器并管理处理器的安全启动处理的电路。该电路接收到交通工具已通电的指示，并向网络服务器发送交通工具的处理器的启动文件的请求。作为响应，该电路从服务器接收与处
