Abstract
A method of supporting secure access to an electronic control unit (ECU) of a vehicle may comprise receiving, from a diagnostic tool connected to the vehicle, encrypted data including an ECU address corresponding to the ECU, vehicle identification information of the vehicle, and a security seed, decrypting the encrypted data, retrieving, from a database, an initialization vector based on the ECU address and the vehicle identification information, calculating a security key based on the initialization vector and the security seed using an application programming interface (API) associated with an original equipment manufacturer (OEM) of the ECU, encrypting the security key, and sending the encrypted security key to the diagnostic tool to be decrypted and used by the diagnostic tool to gain secure access to the ECU.
