    Hi

    I want to know if it is safe to store an AES-key to read a protected sector in a mobile app?

    Suppose that someone extracts the key from the app, can they then create a MIFARE card with a sector that is readible using that same readkey but with different data?

    We are working with MIFARE Plus SL3.

    If it is not safe to do this, how can you securely extract the data from a protected sector without exposing the key to the client app?

    Where can I find more information on the concepts behind this?

    Kind regards,

    Philip
