Hi,
could somebody tell me if the flash report (Entire Flash) is located in the SCK key?
It is possible to reade the SCK key in the lab mode?
Thanks for your help :-)
Best regards

Yes, I am sure. Encryption keys are not in flash memory

SIM only?
Or the keys are then stored on the radio?

Nope, there is special ASIC IC for crypto function

Ok!
Is saved when you insert the SIM of the Key in IC?
Key stored as long as it remains to be "** 00 # #" presses? Or it will be deleted if the SIM is removed?
Excuse my bad english :-)

What is needed to write a Key to the radio?
Keyloader? Flash cable?
Or that only works with a SIM?

No problem, however this hardware is not cheap and not easy to buy either.

Seems only KVL can manipulate with internally protected AIE keys.
******** TETRA radios has no mystic chips inside but KVL must have to protect secret data and algorithms.
