JavaCard OS

Hi All,

I have done my applet but I need to implement copy protection for it. I don't know how to do.
Now I can read all applets in my card via pyApdutool. And also delete. But I want to make my card fully secure. No one can read Access inside of my card. In applet side, I've added a simple manual authentication procedure. But in card side, I need help.

Thanks.

Hi!

For your requirement, you can change the GP authentication keys to protect your card from accessing by others. Check GP specification for the details of PUT KEY command.
