Hi all! I would like to know how to make sure CAP File never be modified by anybody.
I heard that LOAD COMMAND can use the function of DAP, but I don't know how to use.
Hope some body provide me some suggestions. thx

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.
