KC/KI encryption on smart cards

[luxana]

	I've seen semantics of the KC/KI encryption system used on smart
cards for the local PCN cellular system.  Does anybody know whether this
is secure, and where to get more info on it?  The smart card seems to
generate keys by itself that are used by the cellular phone to encrypt its
calls.  Could this be applied as a universal smart card crypto system?
