Security related commands
Description
The response to the RATS command identifies the PICC type to the PCD.
The PPS command allows an individual selection of the communication baud
rate between PCD and PICC. For DESFire it is possible to individually set the
communication baud rate independently for both directions i.e. DESFire
allows a non-symmetrical information interchange speed.
If the PICC needs more time than the defined FWT to respond to a PCD
command it will send a request for a waiting time extension.
Rev. 01.00 — 11 December 2007
Description
In this procedure both, the PICC as well as the reader device, show in an
encrypted way that they possess the same secret which especially
means the same key. This procedure not only confirms that both entities
are permitted to do operations on each other but also creates a session
key which can be used to keep the further communication path secure.
As the name “session key” implicitly indicates, each time a new
authentication procedure is successfully completed a new key for further
cryptographic operations is generated.
Changes the master key settings on PICC and application level.
Configures the card and pre personalizes the card with a key, defines if
the UID or the random ID is sent back during communication setup and
configures the ATS string.
Changes any key stored on the PICC.
Reads out the current key version of any key stored on the PICC.
