...Control Unit) installed in a vehicle. Update software is sent from a server to a vehicle’s communication device. When update software is sent from the server, it may be sent in an encrypted format to improve security. If the vehicle (in-vehicle communication device) that receives encrypted data fails to decrypt it, appropriate measures must be taken. To solve this problem, in this OTA technology, if the vehicle receives encrypted update software sent from the server and fails to decrypt the update software, the vehicle will send a notification to the server that the decryption has failed. Please search for this technology in this contest. <<NOTICE>> The target car brands in this search are limited to US, European, Chinese and South Korean brands. ...
