I am writing functionality of secure channel protocol SCP02. My Init update and External Authentication commands can work without any problem. But when I try to calculate MAC of successive command APDU, it does not get verified with the MAC that is there in JCOP command.
Could anyone help me on this issue? Many thanks.
