4.1 CRYPTO I: Card Authentication
For correct authentication of MIFARE Classic
products the fast CRYPTO 1 stream cipher is
available. The corresponding keys have to be
programmed into the secure non-volatile key
memory of the CL RC632.
Only two commands need to be sent by
application software to turn on CRYPTO 1
secured communication.
4.1.1 INITIATING CARD AUTHENTICATION
The correct key for the authentication has to be
selected from the secure internal non-volatile key
memory and loaded into the internal CRYPTO1
register. Next the authentication command is
transmitted to the card.
After receiving the first message token from the
card, the µ-Controller has to check the

communication status flags. If communication so
far has been successful the second part of the
authentication procedure can be started.
4.1.2 SECOND PART OF CARD
AUTHENTICATION
Data to be transmitted to the card in this phase
are generated automatically by the internal
CRYPTO 1 unit inside the CL RC632. To request
this action the according command has to be
triggered.
The card will respond with the second message
token. Then the communication status flags have
to be checked by the µ-Controller. If
authentication has been successful further
communication with a MIFARE Classic card
continues CRYPTO 1 enciphered.
