how to protect JavaCard Applet?

1. How to prevent others from modifying CAP File content?

2. How to make sure CAP File never be modified by anybody?

I know LOAD COMMAND can use the function of DAP, but study for

a long time still can't understand how to use.

3. Have any method may let CAP File can't load into the card(or use)

after altering?

Hope everybody can offer the suggestion or the method, thank you very much!

DAP verifies that the content was not altered and is allowed to be loaded onto the card. The card personalizer needs to provide you a security domain's DAP key. You need to caclulate a message digest of your cap file and give this information out to the person who is authorized to load the cap file. The message digest is part of the INSTALL [for load] command.
