Las Vegas, NV Inks Contract w/Motorola Solutions for Long-Anticipated Interop System

Better hope they didn't watch last week's episode of Locked Up Abroad.

I guarantee that PD will Encrypt all of their mission cirtical or all of their talkgroups for sure. Why not, they can and will with the use of their APX 6000 and 7000 radios. Like in other postings Las Vegas PD will drink the Kool-Aid from Motorola and opt in and say wow now we can go silent and nobody can hear us anymore. Isn't that great.

Fire will probably have the capability to Encrypt but they will probably opt out because there would be no reason to encrypt and jepordize any critical communication hick-up on the system.

Hopefully within in time some genius will crack this encryption crap and use a keyloader and we will all be back in business.

Also, too with this NSA crap lately I think each cell phone should have an encryption key installed and then when we make calls then we can encrypt our conversations. Why not

Or if you cant beat em, then join em.

From what I've heard about LVPD's many dustups with the local media, expect this system to be encrypted out of the box. I'll be really surprised if it's not.

I like your idea of being able to "go secure" on our cell phones. That'd be neat, but you'd only be able to call other people with the same type of phones otherwise how would they decrypt it on their end and encrypt the voice traffic they send back to you? Plus in full duplex? That'd be something. I think that would work better via VOIP. You could talk securely over the internet using voice packets encrypted with PGP encryption. That's probably doable.

As for some genius figuring out how to crack P25 encryption, here's why it'll never happen:

I thought of a way to systematically search the keyspace based on known plaintexts that occur at various points in a P25 transmission, but the trick would be having a computer with enough room and horsepower to store the entire keyspace's worth of encrypted plaintexts and return results from such a search within a reasonable timeframe, like within our lifetime for example. The keyspace is beyond huge, guys. Really. It's gigantic. Imagine trying to find a planet just like earth - I mean just like it, down to the last blade of grass - in the entire known universe. Now you have an idea of how hard of a task "cracking this encryption crap" would actually be. But let's say you had such a supercomputer with a few petabytes of disk space to store all the trillions upon trillions of possible combinations of the known plaintexts and had them all sorted in a neat little line (ha little) so that you could employ a binary search on them and return the result in let's say a year, which would be pheonomenal speed by the way, then sure - it's theoretically possible and pretty easy (by comparison) to modify DSD to dump the voice packets out, call any number of open source routines to decrypt them using the key you found, and then reinject them into the vocoder portion of that program for playback. But how practical is that? And how many millions of dollars would you spend on such a thing? Hell for a tiny fraction of that kind of money I'm sure you could social engineer your way into the radio shop and bribe one of the techs to clone you a radio.

That's why it'll never happen. It's not impossible, just really impractical.

If you want to find out what's going on (as opposed to listening to po-po chatter) I think the best strategy aside from mass political upheaval would be to create something like Waze but not for boring traffic reports. For crime and other incidents of interest.

Imagine if everyone with a cell phone could get compensated for reporting an incident that they are witnessing. Said incident is then broadcast over other channels to paid subscribers. Or to everyone if there was some other means of paying for all the tip offs.

Next generation scanning.

Not only that, with budgets and police forces being cut to pay for elaborate, unnecessarily lavish radio systems, help may actually come sooner by a crowd of strangers than the police. In my area, the police are hiding, that was a priority but a lot of time when you dial 9-1-1, nobody answers. Not sure what the ramifications could be. Just thinking out loud.

Cutover looks to be in the mid-2014 timeframe (as long as schedules hold up) and it was proposed as a P25 phase 2, 12 channel, 9 site simulcast system with 22 standalone/IR sites ranging from 2-12 channels and will replace the OpenSky system for voice only. My guess is that data will still go over OpenSky. Folks are probably right on the encryption part - LVMPD has privacy with OpenSky right now (which can be ran with AES encryption as a standard feature) so I would assume that they wouldn't want to take a step back with their voice system privacy...but we shall see!
