Thanks for your answer,
I already tough about implementing the authentication process in the reader, but my problem is that I need the key on the client app in order to build the response.
Our application has to work on any android phone, so I it is not possible (and secure) because I should transfer the password in a request from the server.
It is also not possible to store the passwords on the device, as the application should work on any NFC compatible phone.
I suppose the mifare authentication won't fit the requirements of our application.

Do you have another tag that could fit with our requirements?
We need to be able to authenticate a tag with an android app, by exchanging challenges with a distant server.
