A method and apparatus are provided for verifying authenticity of program code for an electronic control unit. In one implementation, a method is provided. According to the method, program code for an the electronic control unit is received. The method may access metadata embedded in the program code. The metadata may identify a source of the program code. The method may further communicate via a network with a server to determine a status of the program code. The method may verify the authenticity of the program code based on the source of the program code and the status.

Verifying authenticity of electronic control unit code

A method for detecting breaks in a border of a network is disclosed. The method may include monitoring network regulation and shaping traffic passing through the border. The method may also include providing, by a first confederate server on a first side of the border, a first connection request to a second confederate server on a second side of the border. Further, the method may include providing, by the second confederate server on the second side of the border, a second connection request to the first confederate server on the first side of the border. The method may also include executing a network diagnostic command if one or more of the first or second connection request is granted. Further, the method may also include copying any outputs of the network diagnostic command to a file.

Method and system to detect breaks in a border of a computer network

Methods and systems are provided for securing electronic control unit code. In one implementation, a method is provided. According to the method, an order for the program code may be transmitted to a developer. The order may include specifications and an authentication key. The method may further include receiving the program code and the authentication certification from the developer and verifying the authentication certificate to determine whether the developer was an authorized source of the program code. The method may generate metadata identifying the authorized source of the program code and embed the metadata in the program code.

Securing electronic control unit code

A computer-readable medium is disclosed. The computer-readable medium stores a virtualized service tool application program for running on a computer running an existing operating system platform. The virtualized service tool application program has operating system software configured to execute as an internal operating system platform separate from the existing operating system platform, and that is configured with settings that permit the computer to communicate with one or more machines coupled to the computer. The virtualized service tool application additionally has a service module configured to perform service-related tasks for the one or more machines coupled to the computer.
