SECURELY PROVIDING DIAGNOSTIC DATA FROM A VEHICLE TO A REMOTE SERVER USING A DIAGNOSTIC TOOL

摘要

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.
