Hello dears
I'm starting to work Secured elements, I have a uicc with its key set KiC, KiD, KiK,which is working fine for one tool , but confused with when other tool is requesting ( S-ENC, C-MAC , DEK ) ?

I figured that KiK is DEK,
but still guessing about the other two :my question is are they the same?

what about the other two , are they the same,if yes :which is which?
KiC is S-ENC ?
C-MAC is KiD ?
"tried to switch but got same error ""check Card Cryptogram failed.""

Is there some specification to explain this?

global platform specs talks about S-ENC and C-MAC, telecom specs ( ETSI )talks about KiC, KiD,

I used the later to access the USIM card with some toll and it works, but pyApdutool requesting S_ENC , C-MAC, & DEK

I could not find any reference to map ( if they are the same ) between those.
