[Jesús Manuel Gómez Fernández]

HI,

I'm usin Mifare SDK Lite and I need to do an authentication to read a file which is configured to request an authentication with a specific key different from the application key.
Is it posible to realice an authentication to read a file which need autentication with a key different from the App key with Lite SDK?

Thanks in advance

Hi Jesús Manuel,

Whether is an authentication needed or not depends on the parameters of the application where the file in bundled. In a case where you have to check very fast whether an access is granted or not, you would omit the authentication. For instance in an access system.

If you need in your case an authentication, you have to select the application first, with the AID SelectApplication(AID) . Next you authenticate with the correct cipher (AES. 3KTDES, etc.) and the key you have decided to use for file read commands. If it was successful, you can read the content of the file.

Kind regards,
The MIFARE Team
