Re: secure channel initiation mode implicit
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. ...

T=0 protocol cannot distinguish between the Lc and Le bytes. So it uses specific status words, such as ...
