OTA keys ?
Posted: Tue Feb 20, 2018 6:50 am
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.""
