I'am implementing the differents implementations of globalplatform scp01 and scp02 on Javacard and I've found a problem.
Can someone explain me how is the mechanism of secure channel initiation on mode implicit?
In the spec I've found perfectly described the explicit way, (pag. 214, E.1.2.1 Explicit Secure Channel Initiation, with an awesome graphic), but the implicit form is very brief...
What are the steps I have to follow to do it correctly??
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
