Motorola Turbo UHF Question. Is Does TDMA mean encrypted?

[MattSR]

YSome people (including one person on this board) have tried to claim that the Enhanced Encryption would be just as easy to 'break' as WEP encryption. The fact that the encryption data is different for each data message and superframe sent, tends to contradict that idea.

Enhanced Privacy/Encryption is NOWHERE near as trivial to break as WEP. I know what the differences are and the way each message is encrypted differently - In cryptographic terms a Nonce or Initialisation Vector is added to the key before encrypting the frame which prevents time memory tradeoffs. In addition to this the first 256 bits of keystream are discarded, which also kills off all the vulnerabilities that were in WEP.

While its not trivial, 40 bit RC4 can be broken pretty easily - just no where near as easily as the half arsed WEP implementation.

Also note - these tricks aren't really tricks or anything proprietary - They're simply the recommendations that Ron Rivest made when the cipher was originally designed.

I can confirm 100% that ADP works as mentioned above too.

If its basic privacy there are 255 keys, you could try them all if its worth your time. If its enhanced privacy it is a 10 digit hex key. There is no built in random generator so I would start with the obvious, 1234567890, 1111111111, 2222222222, etc then phone numbers for the company or the shop who set up the radios.

Also you said he mentioned the key was 64 something, maybe its basic privacy key 64?

Back to OP's original question, no, TRBO does not imply that the signal is encrypted. TRBO implies that the signal is digital, as opposed to analog. Encryption is a feature that is added to the transmitted signal to keep listeners with digital reception capability from understanding what is in the digital signal.
