Use different keysets for different purpose

Post by openxdev » Wed Oct 13, 2021 3:58 am

I am using NXP JCOP 4 (P71) card. There are two stages before the card is being issued.
1. Initialization and applet loading.
2. Write customer profile to applet.

I am able inject a few keysets into the card using PUTKEY command. Is it possible to use or control different keysets for different purposes ? For example, use keyset A for (1) Initialization and applet loading and use Keyset B for (2) Write customer profile to my applet. Or is it better for me to implement SCP02 or SCP03 in my applet for item 2 (Write customer profile to my applet) rather than relying on issuer security domain (ISD) ? Any advise will be very much appreciated.
