GETS isn't the DSN. GETS is basically a way to use the priority bits in a SS7 IAM. DSN, on the other hand, is the modern day AUTOVON. I used to know more about it. All that I remember this late in the night is that there's 2 systems: DSN RED and DSN BLACK. If I remember correctly DSN BLACK is for non-classified communications and DSN RED is for classified communications. For secure communiations they use STU-III phones with some insane key lengths. The key is stored on a paersonal flash memory card that's in the shape of... a key! You plug it into an ITU, turn, and ta-da! That's all that I remember off the top of my head.

Well, like you were saying there is the DSN and the DRSN. DSN CAN be classified with the use of the STU phone/Iridium etc.. I've never personally seen a phone patched into the DRSN but I would think the line would already be classified so no local user encryption would be necessary.. but, using a STU with the network just adds that much extra protection.
The key that you are speaking of is also referred to as the Crypto Ignition Key (CIK). Users refer to the actual plastic "key" looking piece as the CIK (pronounced "sick") and the information on it as the keying material (aka "keymat" aka "key").
