VW-2, VW-3 uses AUT64 with 12 rounds, and starting from page 934 mentions AUT64. ref: https://www.usenix.org/system/files/con … garcia.pdf
Orginal crypto states 8-24 rounds.
This means that the same AUT64 key is stored in millions of ECUs and RKE remotes,
without any key diversification being employed at all.
...
the global AUT64 masterkeys for VW-2 and VW-3 are different, but both can be extracted from the ECU firmware
and possibly from the μC in the remotecontrol as well
VW-4 uses XTEA.
e5561 datasheet explains AUT64 also. ref http://media.digikey.com/pdf/Data%20She … /E5561.pdf
