Keyloader Question

[Thefish561]

I am curious if it is possible to "read" the encryption info from a radio with the KVL. I realize you can "write" a code but how would someone go about getting the information out of the radio witout being the "keeper of the code".

Thanks in advance

If you're not the keeper of the code, then there's no need for you to know the code.

Even if you're an end user of the code, there's still no reason for you to know it.

Therefore, unless you're the keeper of the code, there's no need for you to know the code.

Keyloader based encryption would be severely compromised if any Tom, Dick or Harry could go out and buy and keyloader and just read the encryption out of the radios.

No, the code can't be retrieved from the KVL or the radio.

Moved to the Motorola forum. I don't see any digital voice reference.

The only thing you can retrieve from a KVL is the index ID.

No, the code can't be retrieved from the KVL or the radio.

The above is a correct statement. If you didn't originate the code or retrieve it from another individual there is no way to retrieve it from the KVL or the radio.

Not quite. You can retrieve the KeyID (KID) Algo KID (AlgID) Keyset ID (KSID) Storage Location Number (SLN)

Mind you, in P25 mode (CKR mode) all the transfer done between a KVL and radio is in the clear. If you have a DSO or logic analyzer, a copy of the specs and the KVL you can watch the data transfer on wire and get the key from there.

Once the KVL itself is compromised the keys need to be discarded.

As far as what the original poster is asking - no. You cannot retrieve the keys from a radio.

Thanks for the correction; my terminology seemed sketchy.
