MotoTRBO Capacity Plus- Basic Privacy

MotoTRBO Basic Privacy is a low security XOR scheme to help deter casual eavesdropping.
This is what it sounds like if it were intercepted by a receiver/radio without the proper privacy key.
Given there are only 255 possible basic privacy keys, it is possible (likely) someone will take the time to go through every possible key until they find it.
I recommend enabling RAS to prevent the above attack. If RAS is used, someone with a DMR radio, even if they had the correct privacy key, wouldn't be able to receive any audio.
RAS can provide strong protection against unauthorized repeater access. It also prevents unauthorized DMR radios from receiving any transmitted audio.

Will RAS protect against a DMR scanner too or will a good scanner still pick it up?

I don't own a DMR capable scanner, but my guess would be no. RAS also will not prevent programs such as DSD from receiving traffic. Hytera has an interesting feature called "over the air encrypt" which takes a user defined 128-bit key and scrambles the signalling info such as talk group code and radio ID number. Coupling the above with voice encryption provides decent privacy. Using AES with the above provides very strong security.

As software gets improved and CPU processing gets faster dmr encryption will get broken.

It already is and has been for years unless you manage to get AES-256. Basic privacy offers privacy against scanners and anyone who doesn't try. Enhanced privacy is 40 bit and offers privacy from scanners and casual listeners using SDR programs. Of course I'd never try. This is for informational purposes only.

Hi, sorry to bother you, but do you have any knowledge about the subject of "voice to skull" and about the transmission of voices in a person's head, what frequency can be used and how can it be decoded, I also ask for a friend?
