Dear,
MPCOS-EMV has a crypto-engine(3DES) which it uses it for some specifi(ed)ic purpose.
It cannot be used to encrypt arbitrary data. It is basically used in commands which
have a 'secure messaging' option + almost all payment commands.
>Is it possible to generate 3des key in the MPCOS-EMV card using OCF??
No. You have to create keys outside the card and inject(load) the key unto the card.
>If so, what is the procedure to generate key ?
As mentioned earlier, the cards do not support key generation.
>and How to encrypt and decrypt the data using that key ??
Please go thru the card manual and it should be very clear.
Note on key generation: Please note that you don't really need a key generation module
inside the card. Unlike assymetric algorithms like RSA, 3DES doesn't force you to
derive(compute) the keys in a particular fashion. Ofcourse, it MAY discourage you to
use weak keys like
00000000 00000000
00000000 FFFFFFFF
FFFFFFFF 00000000
FFFFFFFF FFFFFFFF
Warm Regards
