Abstract: A vehicle system and method of secure communication between a vehicle and an external device communicating with the vehicle in a diagnostics mode. The method includes the steps of: receiving a first diagnostic request at an electronic control unit (ECU) from the external device; determining an increased risk of security breach at the ECU based on the [nature of the] first request; and when it is determined that the increased risk exists, providing a misinformative response

Abstract: A communication system in a vehicle is described and various methods for securely providing diagnostic data between a vehicle and a remote server using a vehicle diagnostic tool. The method may include the steps of: receiving at the remote from the diagnostic tool both a challenge question and encrypted data acquired by the diagnostic tool from a vehicle electronic control unit; using the challenge question to determine how to decrypt the encrypted data; and decrypting the encrypted data at the remote server.
