Ha, even if there was one AES 256 was designed to be quantum resistant. It would be reduced to AES 128 bit strength. Still very strong. So strong that if a computer could search 2^80 keys a second it will still take 100,000 years to search just 1% of the AES 128 key space. My guess is the most expensive, purpose built supercomputers today could probably only search 20 - 50 quadrillion keys per second. That's very fast. Fast enough to crack any 80 bit keys (RSA-1024 included) in under a year. Hence, the changeover to RSA-2048.

Pyrofriends Slightly more complicated than Moto BP, but still very weak. Don't be fooled by it being called a 256 bit basic key. No security if the key can be found by performing a simple math op on only 4 basic privacy frames from stereotyped segments of a transmission.

Well, according to me analogue scrambling is only to avoid listening by simple scanners/receivers. Real security is quite zero. I absolutely agree with "RFI Crypto Lab", at the moment only AES can be considered a secure encryption algorithm. Basic encryption uses RC4 encryption algorithm which is no more secure. Hytera implements a very good solution to increase security using "rolling keys". So setting AES + 30 rolling keys is the most secure solution. Of course to use AES you've to pay for a dedicated license, both for Hytera or Motorola.

RFI-Crypto Lab thanks for your answer! What do you think about scrambling in analog channels?
Well, according to me analogue scrambling is only to avoid listening by simple scanners/receivers. Real security is quite zero.
I absolutely agree with "RFI Crypto Lab", at the moment only AES can be considered a secure encryption algorithm. Basic encryption uses RC4 encryption algorithm which is no more secure.
Hytera implements a very good solution to increase security using "rolling keys". So setting AES + 30 rolling keys is the most secure solution. Of course to use AES you've to pay for a dedicated license, both for Hytera or Motorola.
i had no problem obtaining AE31 boards for my nx-5000 series radios and the encryption software from kenwood and now i run all my HT and mobiles on AES 256Bit on ham frequencies in Canada its legal
Would you mind sharing how much the boards cost?
@@rfi-cryptolab4251 my cost was around 400 canadian dollars per cryptographic module. Prices vary depending on wether you are paying retail or dealer cost.

Thank you for the information.
I purchased the AES (DMRA) licenses for my Hytera radios.
They were $275/radio. You can enter a 128 or 256 bit key.
Using 256 they work with MotoTRBO AES.
I have a question. What dose digital sound like on a analogy scanner?
I’ve heard it, it sounds like a helicopter when in FDMA mode but in TDMA it’s different here are some links for you to listen,
DMR FDMA:www.w2sjw.com/sounds/DMR TDMA_Simplex.mp3
DMR TDMA:www.w2sjw.com/sounds/DMR_TDMA.mp3
By the way, TDMA is short for. Time division multiple access
FDMA it’s also short for. Frequency division multiple access when used in Symplex for amateur radio
like a bunch of clicks and pops. Even unencrypted. Its exactly that - a "digital" signal. Its not modulated the same, so an analog scanner or even another analog radio tuned to the same frequency will just be like "yea, I have a signal but - I have no idea what this is" and you just here this annoying popping sound that sounds like a machine gun lmao. Analog radios typically us FM (Frequency Modulation) so it has no idea what to do with a digital signal thats modulated a completely different way
If someone hacked the police and just cloned the same key for the all the police radios. They would be fucked
Decrypt Alg =AES .DSD+
You can by a cheap Chinese DMR Radio and Find the Scramble Code,
How do you get DSD+ to decode encryption?
you can't.
its virtually impossible to decode AES 256 at all. The most powerful computer in the world can take nearly 7 Billion years to get even close
Des56 you can
How can I contact you?
Why right here me lad.
Is it AES? Are you sure?
Uh huh.
Is there a way to decrypt (not decode the digital) signal that my local police use? They use a digital trunk system but it’s also encrypted.
Thanks in advance

Yes, become a cop and get hired by the department.
There is also the federal prison option.

Please do explain.
There’s no possible way to just listen to police encryption? I heard if you use a method that isn’t a scanner it’s still considered a legal loophole according to FCC laws. Is it automatically a felony?
Cool DG scanner😷 💩 😷
what usb dongle types do you utilize to test with?

In this video I used a disc tap.
I sometimes use an AirSpy or a nooelec premium.
Hello my friend
When I hear in my country, I don't hear anything
I find guidance in writing
Enc Group call; TG = 1RID = 5136068
Is there a solution to this thing? I want to know what, please
Can I break AES256 for P25? 😁
NO way to break it i wish i could do the same
