DSD+ DMR encrypt decoding

[tromb]

If I have the encryption key, there is a possibility that you put in the DSD + and decode traffic.

Thanks and Best Regards

Nope.

 

[tromb]

Is there a possibility that sometimes have this function ?

Is there any software that can allow such a thing?

Thanks and Best Regards

Nope.

(hate to be an echo but, you're not going to discover any help or information about communications decryption of any kind around here so...)

If it is legal to do so (and I can only assume you have the key via legitimate means), then the only two options are:

1. Assuming RAS isn't used, buy the same DMR equipment that's being used and then add the key to this to decrypt, or

2. If (and only if) the Motorola Basic Privacy flavor of encryption is being used, then acquire an ADCR25 receiver and it will decrypt it without the need for a key. Note you can no longer buy an ADCR25: they were withdrawn from sale shortly after some simple decryption features were added....I'm sure you can draw your own conclusions as to why it's no longer for sale !

I have the same need ... so please let me know if you have I solution
Thank you!

If its motorola basic privacy its easy, you don't even need the key number as it can be determined from the AMBE frames and is very easily descrambled.

.....but it still won't work with DSD+.

I rarely see anyone using BP in my area. Those that do are usually using lower tier radios like CP200d etc. As you mentioned it's extremely weak but it keeps the scanners out.

BP encoded frame

I know the problem is discussed, but i would know if there a way to extract the encoded Basic privacy frame bits from DSD+ or previous version in order to check and try an offline manipulation to remove the encription?
Could be nice to have a binary output in DSD in order to perform some sperimentation, any idea if is possible to modify DSD source file to add this functionality?
Thanks everybody!

It would be trivial to modify the DSD source code to do this. It's probably on GitHub.

Such recoding would also render any distribution or use of that version of the software unlawful.

How don't you know it isn't already? I think he is suggesting to the DSDPlus team to add this feature that is all.

 

[DaveNF2G]

Your question makes no sense.

 

[woodpecker]

Why is that unlawful?

 

[toastycookies]

Why is that unlawful?

It is not.

Again. Illegal.
