Abstract:
A method of providing access to a password-protected electronic control unit (ECU) using encryption includes generating a cryptographic key for the ECU using a master password, a serial number of the ECU, and a password-based key derivation function; converting the generated cryptographic key into an ECU password; and accessing data from the ECU using the ECU password.
