The mechanism is described in the GPC Specification 2.2.1 section E.1.2.2.
The steps are much the same as the explicit except there is not INIT-UPDATE/EXT-AUTH commands to deal with. When the first secured APDU is received (CLA = 0x84) you follow the process to generate session keys and verify the MAC. The card spec outlines how to generate a MAC with the session keys.
I am a Javacard engineer from China, I have an question which trouble me for a long time,Can you solve it for me?
The question is how to creat a SSD? I can use which APDU? Thanks. My e-mai is email@example.com. l
It is the explicit mode, not de implicit
Yes, finally I found it, but in fact I decided not implement this option because it complicates a lot my code, and in future revisions of GP it will be deprecated.
Thanks for your help
