5.10.4. MIFARE DESFire EV2 : Authentication¶
Warning
To run this example, you would need the nxpnfcrdlib component for which a Non-Disclosure Agreement(NDA) needs to be signed. Please contact your FAE for additional details.
5.10.4.1. Prerequisites¶
Section 5.10.2 MIFARE DESFire EV2 : Prepare MFDFEV2 must have been executed, so that the MIFARE DESFire EV2 card has the required credentials. For relevant platforms, a KSDK package is available. Please import and execute the example MIFARE DESFire EV2 : Prepare MFDFEV2.
Section 5.10.1 MIFARE DESFire EV2 : Prepare Secure Element must have been executed, so that the Secure element has the required credentials. For relevant platforms, a KSDK package is available. Please import and execute the example MIFARE DESFire EV2 : Prepare Secure Element.
Section 5.10.5 MIFARE DESFire EV2 : Change Key must have been executed.
Section 5.10.6 MIFARE DESFire EV2 : Diversified Change Key must have been executed.
Note : Order of execution se05x_Ev2PrepareCard, se05x_Ev2PrepareSE, se05x_Ev2ChangeKey, se05x_Ev2DivChngKey, se05x_Ev2AuthTransaction.
Bring Up Hardware. (Refer Development Platforms)
Connect RC663 to your microcontroller. (Refer mifarekdf-rc663)
5.10.4.2. About the Example¶
This project is an example demonstrating the Mifare Desfire EV2 authentication using Se05x. After authentication, it performs encrypted communication with the desfire EV2 card.
It uses the following APIs and data types:
5.10.4.3. Running the Demo¶
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo
If everything is setup correctly the output would be as follows:
