Security related commands

Command

Description

Authenticate

MIFARE DESFire EV1 and the reader device show in an encrypted way

that they possess the same secret which especially means the same key;

this not only confirms that both entities are permitted to perform

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

Change KeySettings

changes the master key settings on MIFARE DESFire EV1 and

application level

Set Configuration

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

Change Key

changes any key stored on the MIFARE DESFire EV1

Get Key Version

reads out the current key version of any key stored on the MIFARE

DESFire EV1
