encryption

Hello, I've been monitoring this 800mhz DMR Capacity Max system for a day now but I ran into this issue that I have never experienced before. Most of the talkgroups are in the clear, but today I recived what appears to be really faint mumbling with loud beeps on top (like PTT grant and some...

Hello, all, I will thank all in advance who can help me 'understand' some of this. I am really new to this modern type of scanning. I have a Uniden SDS-200 which I'm trying to program a few local P25 trunked systems into my scanner. I spoke with someone at Uniden who looked up my county (San...

I recently got Two Bridgecom Mavericks and Converted them to do NXDN for Public Safety with my Fire Company. Very well performing radios so far but I have two issues... 1. The NXDN ID's are Picky of when they work 2. Status Messages don't Properly Work from time to time 3. My main issue is I...

I just moved from south of Ames down to Des Moines, and Story county sheriff is often linked to polk co simulcast extending down into Des Moines area and I've started to notice that Law 1 (28501) and LEA (28502) have shown up as encrypted for me, they've never shown up as encrypted when I lived...

Hi, I have a Baofeng DM32UV, I have a couple encryption keys loaded in it, encrypting voice that i transmit from the baofeng works fine, and I can decrypt it on my Motorola DP4801 (XPR7550) however, voice that is encrypted by Motorola, either AES256 or RC4 is not decoded on the baofeng, I just...

Hey, I was wondering what's the procedure to add/purchase encryption algorithms (such as DES or AES) on an APX radio? The device has secure HW (MACE). Thanks

Hello, I have seen that you can load encryption keys to APX radios through KFDtool with just a programming cable. Is this true? Every time I try, I get "Error -- A connection attempt failed because the connected party did not properly respond after a period of time, or established connection...

I'd like to gather information on which "budget and entry-level" DMR radios have encryption compatibility between models. Hopefully we can use this thread as a repository for this information across manufacturers and models. If anyone has experience in this space, please let us know. It would...

I heard from a few admins from Seminole county that they are upgrading to APX nexts and encrypting all their talkgroups even fire. I don’t know how this would work on the Orange County system 46C for their patient transport to Seminole county. If anyone has more info pls let me know thx

Hi all, I recently moved to the roanoke, va area and i'm trying to get a handle on why some freqs aren't coming through. I've read that roanoke city and county both have all law enforcement activity on encryption but i also cannot seem to receive county fire frequencies on my sds100. Is fire...

I remember during the time OSP and everyone else were still on the Moto SmartNet Type II system, Delaware Post 21 had a TAC channel listed in the database, below the main talkgroup. I remember they had the option to use encryption but were mostly in the clear (De). Does anyone know if such a...

I'm seeing these unknown link control messages carried in a contiguous chunk of TDULC messaging on some Phase 1 traffic channels. In both examples, it was immediately following an AES-256 encrypted group call. Within sdrtrunk I'm calling these RADIO REPROGRAM, but I'm not yet certain of the...

I haven't found this exact question answered, but I am monitoring a DMR one freq system run by a business. I'm curious, if they decided to, how easy would it be for them to encrypt their communications? Is it as easy as simply turning on a setting, or would they need to incur extra costs? I know...

Hey all, I'm really hoping this doesn't turn into a flame war or anything, I'm just trying to better understand the key differences in implementation. Question I'm aware that companies like Anytone, Hytera, Motorola, etc. offer encryption in their DMR radios, and I know that Anytone and Hytera...

For anyone using 128 bit encryption, I have a Python script that will generate a cryptographically strong key that involves 14 rounds of randomization, SHA-512, PBKDF2, HMAC, a 64 byte initial token, a 64 byte dynamic salt, and 1 million iterations. They come out strong, when I histogrammed over...

Heard from a reliable source that Suffolk county is going FULL encryption in 2029. im so upset

Hello, I have some issues with received encrypted voice with my Anytone AT-878UV Plus and Hytera Handhelds, which operate at Basic encryption type, 10 characters length. The result I get that via repeater mode, Hytera receives my encrypted voice well and on my Anytone the only thing I get is...

The county I am based out of is stated as "Fully Encrypted" on Radio reference. However, someone has a Broadcastify feed for said county and can pick up the county. How is this possible? Is there something wrong in the Radio reference database? He posted some frequencys for "Point to point...

Is it possible to detect encrypted talkgroups (BP / EP / AES) on Motorola Connect+ systems by scanning the Control Channel?

During the tragic active shooting at Michigan State University, police units requested tactical/encrypted channels but were then notified by the dispatcher that interoperability may be compromised since not all units on scene have access to the same encrypted channels. This was becoming a...
