Import DMR Radio Privacy/Encryption Strength Question

[RayAir]

Do any of these import DMR radios like the CS750 or Tytera MD-380 offer voice privacy at least comparable to MotoTRBO Enhanced Privacy (40 bit) or ADP, preferably a little stronger?

I know the CS700's I have only offer Basic Privacy which is a 4 hexadecimal key. So I'm guessing it is 16 bit software (non cryptographic) scrambling with 65,536 keys. I guess that will keep most people out, but I bet there's a few on this board that could figure the key out. It also appears each vendor has their own privacy/encryption schemes (ex-CS700 Basic Privacy not comparable with Motorola Basic Privacy etc)

I'm looking for an option without spending a lot of money as we will buy these radios with our own money.The radios will be used for surveillance off- network our normal unencrypted digital system.

Import DMR looks to be the best bet so far (cost wise).

If I can't find a good DMR option, I could refurb our old LPE-200 radios. They have AEGIS and have the VGE key still loaded (infinite key retention) and can be used on the ITAC channels. But all batteries and chargers need to be replaced and I have no key loader or way to disable a lost radio, etc.

Any suggestions?

Update: Just got an answer from CS Inc. They are working on adding AES to the CS750 radio.
Good encryption looks like it is finally coming to entry level DMR radios.

I know you posted this two months ago Ray, but the Tytera MD-380 with firmware updates now has enhanced encryption which is 128 bit. I am sure soon enough it will be 256 bit as well given in due time!!

Yep. Hadn't discovered the 380 at the time I originally posted this.

I decided to download the md-380 CPS and was shocked to see that it took 32 digit hexadecimal keys for "Enhanced".
