Vehicle over-the-air update authentication system and method

A vehicle with an over-the-air (OTA) software update and authentication system, comprising:

• a vehicle computing device, including one or more processors, a communication device for communication with a secure server via a network, and a non-transitory computer-readable storage medium having a plurality of instructions stored thereon, which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receive and install an OTA software update stored in the secure server, the stored OTA software update having an associated first checksum value;
• receive a request to authenticate the installed OTA software update, the installed OTA software update having an associated second checksum value;
• send a signal to the secure server representing the second checksum value to be compared, by one or more processors of the secure server, with the first checksum value;
• receive, from the secure server, a signal indicating if the compared first and second checksum values match or do not match;
• determining the installed OTA software update is authenticated if the received signal indicates the compared first and second checksum values match;
• and
• determining the installed OTA software update authentication is failed if the received signal indicates the compared first and second checksum values do not match.
