mifare desfire changed key ok, but authenticated failed

[zhanghuiquan]

hi guys,

There was a strange problem reading the mifare Desfire card.

I have several white CARDS with the key set to 0 by default. After I pass the authentication by command, I send command to change the key. The card's return status is shown to be successful.Then I used the changed key to authenticate, but the key could not be authenticated.
