mechanism of secure channel initiation on mode implicit

Post by shibulijack » Sat Mar 19, 2016 5:36 am

Hey all.

Can someone explain to me how is the mechanism of secure channel initiation on mode implicit? I found the specification which described the implicit way, but it's very brief.
Hope somebody tell me the steps I have to follow to do it correctly.

Thanks~

The steps are much the same as the explicit, except that there is no INIT-UPDATE/EXT-AUTH commands to deal with. When the first secured APDU is received (CLA = 0x84), follow the process to generate session keys and verify the MAC. The card spec outlines how to generate a MAC with the session keys.
