VAG Manual SFD Unlock Token for Volkswagen and Audi SFD Unlocked One-Time Access
As of 2020, Volkswagen AG will introduce a new procedure for Vehicle Diagnostic Protection (SFD). In order to utilize the SFD procedure, it is necessary for users to be registered in advance on the SFD back end. For the ODIS SFD unlock you need to use ODIS 14.1 Engineering system and VAS6154A or DOIP Enet cable.
SFD will be introduced in two project stages:
- Stage 1 comprises access protection of protected diagnostic objects in control units and the verifiability of this access on an individual level. The protection requirement will be defined for specific control units and diagnostic objects. The protection requirement is limited to specific writing services (codings, adjustments, parametrizations) and routines. Normal reading services (e.g. readout of control unit event memories) will not be SFD-protected. The functions of data string downloading with boot loader data strings, flashing and/or update programming as well as flash data security are also not affected by SFD.
- Stage 2 includes, as a supplement to stage 1, tamper protection of diagnostic contents upon integration of the diagnostic contents by end-to-end safeguarding of diagnostic data between VAG IT back-end systems and control units.
In order to be able to log access to diagnostic contents requiring protection in the future, the IT security organization requires strong user authentication to be enforced. It is, therefore, necessary to use two-factor authentication, which can be implemented, for example, by using
• PKI-cards
• SecurID-cards
• Applications that generate one-time passwords (e.g. Google Authenticator or Microsoft Authenticator).
In the first transition phase, however, weak authentication by way of a username and password will initially be introduced when using the Dealer Portal. The transition to strong authentication by means of the Group Retail Portal will be developed in parallel.
The SFD process requires the vehicle diagnostic tester to have an online connection.
The aim of SFD
Product analyses in the VW Group have shown that there is an increased requirement for the protection of data in vehicles. This is also the case for Vehicle Diagnostic Protection. The previous procedure (activation of security access by way of a 5-digit login code) no longer conforms to the state of the art. As of 2020 – beginning with the market entry of the MQB37W (Golf 8) – there will be a cross-brand introduction of the SFD procedure in order to provide Vehicle Diagnostic Protection.
What is SFD?
Vehicle Diagnostic Protection (also known as SFD – Schutz Fahrzeug Diagnose) is an additional security layer that requires authorization between the vehicle and manufacturer. It may help to protect people from any fraud, by providing information on who and when has made modifications to the control unit. This protection applies to the models manufactured from 2020 with the MQB Evo (VW Golf 8, Škoda Octavia IV, Seat Leon IV, Audi A3 8Y, etc.) and the MEB (VW ID.3, ID.4, Škoda Enyaq, etc.) platforms, restricting such features as adaptations, coding, parametrizations. Control units protected by SFD: Engine Electronics, Central Electrics, Instrument Cluster, Gateway, Multimedia Unit, etc.
