Customize JavaCard ATR
I have a legacy contact card (non java card). I am able to emulate the legacy card command set. Would it be possible to also change the ATR of my javacard to be the same as my legacy card ? From my understanding, ATR defines card communication parameters and since each chip has its own properties, d...

Disabling Issuer Security Domain
I have a few sample java cards (JCOP4 P71). My questions: 1. For my application, no loading or deletion of applet is allowed once the applet is loaded into the card. Is it a common practice to disable the selection of ISD once applet has been loaded into the card ? Is changing the ISD keyset suffici...

AEADCipher in java_card_kit-305u3

SCP02 Shared Secret Key Provisioning
I have java card that supports SCP02. From what I read from Global platform specification, both host and applet must have the same 3DES key. What is the right approach to provision the shared key into the applet ? Or supply a seed (e.g card uuid) to the applet during applet load/install and derive t...
