Karsten - this is the only ref I've ever found that's publicly available: http://www.informatik.uni-augsburg.de/lehrstuehle/swt/se/teaching/fruehere_semester/ws0506/javacard/Dokumentation/UserGuide.pdf

See table 10.

Note that instead of using the diversification data from the response to an Initialize Update, this document uses data from the CPLC.

>>My card implements the Visa Global Platform VGP 2.1.1 Configuration 3. And I have troubles with External Authentication. I tried to use different key derivation schems. In particular I tried 'visa2' scheme. But card cryptogram that I compute on the host is wrong. Can somebody provide me what key derivation scheme should I use with GPShell? Or may be libGlobalPlatform doesn't support VGP 2.1.1 Configuration 3 key derivation scheme?
