What is SCP02 used to do? Is it securer than SCP01? Anyone can give me a explanation in brief?

You can refer to annex D/E of the 《GPC_Specification_v2.3.pdf》.

The Secure Channel provides a secure communication channel between a card and an off-card entity during a Application Session

, GlobalPlatform Card Specification says.

There are three kinds of Secure Channel Protocol(SCP), SCP01, SCP02, SCP03.

And SCP02 is the most common one.
