8 DESFire command set

This section contains an overview of MF3D(H)x3 command code. A detailed description

of all commands is provided in [1].

8.1 Secure Messaging Commands

Table 4. Secure messaging commands overview

Command

Description

Authenticate

Authentication as it was already supported by D40. Only for

KeyType.2TDEA keys. Note that the PICC only performs encryption

operations. After this authentication, the D40 backwards compatible

secure messaging is used.

AuthenticateISO

Authentication as already supported by DESFire EV1. Only for

KeyType.2TDEA or KeyType.3TDEA keys. After this authentication,

EV1 backwards compatible secure messaging is used.

AuthenticateAES

Authentication as already supported by DESFire EV1. Only for

KeyType.AES keys. After this authentication, EV1 backwards

compatible secure messaging is used.

AuthenticateEV2First

Authentication for KeyType.AES keys. After this authentication, EV2

secure messaging is used. This authentication is intended to be the

first in a transaction.

AuthenticateEV2NonFirst

Authentication for KeyType.AES keys. After this authentication,

EV2 secure messaging is used. This authentication is intended for

any subsequent authentication after Cmd.AuthenticateEV2First in a

transaction.

8.2 Memory and Configuration Management Commands

Table 5. Memory and configuration management commands overview

Command

Description

FreeMem

Returns the free memory available on the card

Format

At PICC level, all applications and files are deleted. At application

level (only for delegated applications), all files are deleted. The

deleted memory is released and can be reused.

SetConfiguration

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.

GetVersion

Returns manufacturing related data of the PICC.

GetCardUID

Returns the UID.

8.3 Key Management Commands

Table 6. Key management commands overview

Command

Description

ChangeKey

Changes any key stored on the PICC.

ChangeKeyEV2

Depending on the currently selected AID, this command updates a

key of the PICC or of one specified application keyset.
