Digital encryption video

[p99qa40]

is it p25 with voice inversion and des xl or dvp xl ???

[SnrSergntNEDDY]

Christchurch NewZealand police use p25 encryption, recently a small FM transmitter bug was located in a police vehicle, it had been planted and was broadcasting what was heard, $19.95c and the million dollar system was beaten

[fireman3130]

Bushes patriotic (non-patriotic) laws have had alot to do with Encryption

[file83]

Why don't you guys just order those quantum decrypting demodulators from China off eBay? Ooops.....did I just say that?

[aetechllc]

@file83

Exactly!

[alpinestarslidar]

@file83 Because, they do not send the encryption algorithms through the radio transmissions. This is not simplistic encryption. Even if you did eventually crack the keys to the encryption they rekey them every 24 hrs or less. Making your little decryption boxes pointless. It took a kid in Croatia 23 1/2 hrs. to break the code with the at the time 3 yr's ago the fastest supercomputer known to man. Good luck. I doubt some cheap Chinese decryption box is going to decipher the hidden messages.

[file83]

@alpinestarslidar That "WOOSH" sound you just heard was the joke flying over your head.

[EYEOFASERPENT]

Like alpine said. Not simple encryption. The radio I am assigned uses multiple types of encryption and changes day to day along with the keys. One day it could be ADP, next DES OFB type and so on. It is called OTAP. It is rekeyed a couple times a day and the codeplugs are also encrypted with a password changed daily with OTAP within a few seconds to less then a minute. The whole agency is done. Usually only a couple of people know in admin what it is. Even they have a admin watching them.

[w9x7cv3vg6]

well I think that if the system can make gear for them to be able to decode then our scanner makers may soon come across the same technology to be put in scanners but we need to be able to recive the cell frequencies from say 820 to 848 mhz, with the ap25 card,wouldnt that mess their minds up.I have two receivers now that have non stop but I cannot get the digital,I wonder if a ap25 card could be engenered into a yaesu vr-5000 ie..thanks

[Skumling]

Why don't you use CTCSS on it?!

[alpinestarslidar]

@Skumling Let's see Skumling, perhaps because this is "digital system's" Not analog that require ctcss coding, and ctcss coding doesn't keep you from hearing anything. It's only for transmission purposes. It may help you distinguish someone talking close by on a like frequency but that's merely all, this feature is not used on the digital comms. As it's not nessacary.

[Skumling]

@alpinestarslidar Thank you :)

[The73rocket]

You and I don't have to put our lives on the line. It's not just honest people that own scanners. Scumbags can get them too. If I'm gonna rob a store and I know that there's an open channel I'm gonna get a scanner so I can listen for when the police are dispatched so I can get out of there ASAP or hide when I know they're on-scene (they'll radio that in) so I can ambush them. Encryption makes sense. Calling encryption murder is what makes no sense. Can you even relate those two logically?

[mkeeble1989]

@The73rocket you are missing the point. you can't burn down the house to roast the pig.

[alpinestarslidar]

Thankyou XxzombielandxX I agree. That would be some motorist friendly legislation.

[XxzombielandxX]

I believe cops have computers in there cars now. If perivate info/data is exchanged it should be done there and there only. I guess encription will get them off their goddam cell phones so they can use the blinker and obey other driving laws that they dont have time to do now. The mainframe keeps all calls that were transmitted maybe there should be a book in pdf. published that can be requested at the end of every month.

[alpinestarslidar]

@XxzombielandxX I strongly disagree. What ever happened to your 1st amendment right's of freedom of the press? Why is the press, and their associated members not allowed to know what is being discussed behind closed door's? My question, "What is it we are trying so briskly to hide?" What don't we want the press to know about? They even brag on the pages for these chip's about, "How they shall keep media station's from hearing about potential news event's."

[XxzombielandxX]

@alpinestarslidar Youre exactly right! There should be a law introduced. Any data or info pertaining to said violation, that is digitally encrypted cannot be entered as evidence in a court of law!

[alpinestarslidar]

Band? Coldplay...Song title "Yellow." Year of album roughly 2000.

[scpd613]

what is the name of that song/who sings it? thanks.

[MrScrappydue]

nice video

[MrScrappydue]

I have a pro-164 and while I was listening to it a young loud mouth came buy and said my bro has one and he fixed it so he can hear every thing up hear(phone calls) I had one back in 95 and I remember hearing people on phone calls.Why cant or dont I hear them with my new one? Great video by the way.

[CryptoDriver]

How is this murder? You most certainly can encrypt your own personal communications all day long. Ever hear of PGP? Sorry bud, but if you don't have a need to know, you won't get to. All radio transmissions are recorded and available later. Sorry about your luck, but you can thank the criminal element.

[oterotularosa]

sad that it is going to this. sad that phases of end 2 and up will slowly but surely encrypt everyone in the gov. allot of people say no but yes. i know first for fact. i disagree with it that everything needs to be encrypted. allot of people say it wont happen bc of cost, etc but grants are paying for it, new bills require all new radios for govs to have encryption of either, des... opensky.... pro voice and afew others.

[azerty800]

stop the music !!

[kalafoyi]

Well, you can thank the criminals for this.

[alpinestarslidar]

To bad the average criminal wouldn't even understand the half of how to even program such a complex system and device. Considering they aren't even using straight frequencies anylonger. 90 percent of the general public including alot of HAM's don't even understand how to properly program such a device "Digital scanner." I had one on the ham ask me just last night that's been a ham for 20 year's if i'd come over and program his, as not even he a FCC licensed person knew how, yet criminal will?

[billybassman21]

In Houston (Harris County) it seems for now that only the tac and special ops are going to be encrypted. We'll see if that changes and what will happen when Houston PD switches to the Astro APCO-25 system.

[Mainsail76]

I believe it's against the law to "decrypt" encrypted radio traffic. So, don't expect any scanner or device to come along to allow you to listen. They days of us citizens keeping tabs on government and law enforcement scheming is coming to an end thanks to digital. Oh, the government can listen to your phone calls, but you better not listen to their radio traffic. They have a "need to know" when it comes to your life, but you shouldn't know what they're up to. Thugs!

[CryptoDriver]

You're an idiot dude. I have personally been involved in cases where burglars were listening to scanners to avoid getting caught. It's called communications security. The transmissions are recorded and available after the fact for FOIA requests. Right to know doesn't necessarily mean right to know in real time.

[Mainsail76]

@CryptoDriver  My point silly boy was that THEY can listen to our private phone conversations and read our private e-mails without a warrant in real time. You know, "warrantless wiretapping?" But the reverse isn't true when it comes to their comms. Our privacy is just as legit as theirs. You say in another post, "sorry, police officers have a right to privacy." Well guess what, so do I. And don't think for a moment that they won't redact things in a FOIA request document or recording.

[CryptoDriver]

@Mainsail76 Maybe the feds can do all that, but your average street cop? Not.

[BGVAC31]

@CryptoDriver Whats with the name calling you could have just said your whole paragraph without the idiot bullshit. I'm sure you can be more mature than that.

[hondaus90]

i heard that you can take a uniden bc396xt scanner and modify it with a discriminator output, and get the right software and you can decrypt the audio, but it has to be plugged into your computer.

[Dusty696969]

Iv listened to scanners my whole life and just spent 600 bucks on a digital scanner so I can hear the new digital freqs here in the StL and now this crap. I think over time someone will get hold of a encryption chip and revers engineer it and sale them installed in scanners to decrypt the freq and over time just like digital scanners, scanners will have them in there. What do you think???

[Dusty696969]

Also I heard of some scanner box you hook up to your computer and scan from that on your computer with a program that can decrypt them. I read about it but dont know where to get a scanner box or that program. I found things like short wave radio boxs and stuff but nothing scanner. If anyone knows please let me know.

[CryptoDriver]

Not without the encryption key. AES is uncrackable, not to mention the keys probably rotate automatically at a set interval. Sort of like a modern day Enigma machine. You can know the entire process of how it is encrypted, but without the key, you're out of luck.

[Dusty696969]

So the people who created the key the program the whole 9 yards could not get no info themselves. I understand that some things need to be kept under radar. They should have channels to switch to that are encypted in times like these. Now days with digital scanners there are a lot less people willing to even try them. They are a little more complicated than the old day analog scanners.

[radioxdeath]

encryption is heavily abused where I live. They use it to dispatch burglaries or bank robberies whatever crime that is being committed that needs a scanner to assist the criminal in escaping. Unfortunately that's what they don't use if for mostly ,its "hey man can you make sure you, pick me up a can of chew on your way back to the station?" Or "hey man did you get that chicks number when you pulled her over" I've heard this before. Waste of technology and most importantly tax dollars!!

[hondaus90]

GREAT VIDEO.

honestly says a lot

its sad how the government departments would invest in these multi-million dollar 2-way radios, just so we cant hear whats wrong with the world

...sad...

[BGVAC31]

@hondaus90 The best is that most States, cities and towns are putting up these multi-million dollar radio systems but yet lay off nurses, police officers and firefighters because they don't have a budget. I think it's a waste of money. There's other ways to keep things hush hush within a police agency, it's disgusting how these towns, cities just spend our "We The People" money and comeback to us saying they have nothing. It's a big shame.

[cangrejeraub]

ummmm why would you want to monitor radio traffic. what goes on in these communications is noone business. You want know what the government is doing..... then get a job within the government.

[mannydeguzmanjartist]

You simply want to monitor radio traffic to get in touch with your community especially during disasters and emergency. It is more reliable that watching edited news on TV. TV news are sometimes biased on bringing up the events, and monitoring traffic is the only way you could find real "news" as it happens live.

During times of calamities, monitoring traffic could save lives. It gives you a rough idea of the safest places for refuge, and safest place to go.

A scanner is a survival radio.

[ten8goa]

Typically its SWAT, NARCOTICS, ATF, DEA, US MARSHALLS etc. that are encrypted. Sucks, though 'cause they have some good radio traffic.

[alpinestarslidar]

That is not totally true at all. It totally depends on your area, and how anal your officer's really are. They can encrypt whatever they deem fit.

[Dreamlgider]

Police here use 84MHz and cell phones !

[zoltan656]

so you can hear them with modified FM radio .

[Dreamlgider]

i never tried it yet, but i have heard of people modifying regular radios to receive that freq.

[6Ott7]

Is there any way around the encryption to listen to the dispatch?

[alpinestarslidar]

No, and according to US Law, it is now illegal for you to even attempt to monitor their Digitally encrypted communications they had your freedom of information act of 1934 abolished in this respect. You don't have the right in the USA to monitor them anymore. Which is the purpose of this film to inform the public.

[gezelle007]

well where i live there is no current law for scanners, and another thing is that all the public safety channels arent trunked and they arent encrypted. but they are still on uhf. my county has thoght about chaning to a full trunking digital system but that never happened. so they just went to uhf.

[magicjellybeanz]

I wonder who will come out with a decoder...

Matter of time-

Love my BCD-996T!I have one in the car and one in the home.

[TheMightyKinkle]

im assuming DAT is data and LNK is Link, but what are they?

[alpinestarslidar]

Yes, very much so.  You nailed it. Dat is Data, and LNK is link. Yuppers.

[TheMightyKinkle]

but what are they then?

[alpinestarslidar]

LNK would mean Link to the repeater. Data would Mean Digital Packets I.E. Data The packets are sent most likely to let the scanner, or users radio know if the repeater is open or Active for use. I.E. "The famous Busy tone" that officers can now receive on the new Digital system and have to wait for the "Line" in essence to not ring busy in a way. Data could and can also Mean Harmfull interference. There are Data Channels out there for sending info. The BCT-8 has a filter for this as well.

[TheMightyKinkle]

wow you know loads about radios, i only know basic and some intermediate stuff

[alpinestarslidar]

Also, it is probably also saying Dat because most Digital repeaters run on what's called a "Controll channel." Meaning they transmitt and endless supply of garbage sounding transmissions unless programed as a trunked system within a digital scanner. If you perhaps want to see what im discussing just take a regular digital scanner go to radio reference for your area, and attempt to just listen to the nearest controll channel's as a plain freq like you used to in the olden day's.

[alpinestarslidar]

You'll instead hear and endless sound that mimicks what i call "A radio left near an idiling firetruck. Some people call this "motorboating." I personally think it sounds more like a radio left right on the hood of a dang firetruck. What your actually hearing is the Data constantly being transmitted from the repeater to any incoming radio from the Computer connected to the Repeater that let's any incoming radio know, ok this frequency within the public saftey pool is either open, or taken.

[TheMightyKinkle]

yes i have heard this before, it just sounds like a truck engine noise is being transmitted, i have always wondered what that was, i thought it was on a construction site or somthing and you can hear all the trucks

[alpinestarslidar]

Then it goes, ok this channel within the Public saftey pool is open. Because they don't truely use frequency as a term like they used to. The radio's on a digital trunked system in an essence frequency hop. Meaning frequency may only be temperory, hence the computer, hence the data packets to let the rig which freq to hop to next so that an incoming station could always get through, and not every freq is being used at everytime. This free's up space supposedly. And creates Virtual channels.

[alpinestarslidar]

So it's nothing for a police rig to have 120 virtual channels. Virtual meaning they don't truely exist. Technically speaking they don't all have their own dedicated freq is what i'm saying. The freq is designated by the computer/repeater combo, So you may hear your local fire dept on 867.6550 then next hear the police dept on 867.6550. Although in the officers car he never hear's this occur. It's seemless to him or her. Hence the constant "Data" transmission.

[alpinestarslidar]

I hope that better answers all your questions. As for Link a little more in depth on Link. All the link is telling you is that the connecting from you to the Repeater/computer is there. It is active, and if someone would have spoke you'd hear them.  It's telling you the Link between you and whatever your trying to hear is good, and you should hear any transmission from that repeater.

[TheMightyKinkle]

yes thanks, unfortunatly in the UK we cannot listen to the police as they use a digital TETRA Airband system and you cant by any scanner in the UK that could listen to them, and if people hack there scanners this is highly illegal

[alpinestarslidar]

There honestly is none. Thats the truth. And now you know. Tell a friend about your govt's disregard for spending. The reason sir they want to keep those airwaves silenced is to keep You from hearing what they are doing, the media, and other branches of the Public sector. Don't beleive me look at what they brag about on the chips they sell even to encryt analog transmissions yes that day is here and has been for awhile too, they can now encrypt analog transmissions too by adding a chip.

[alpinestarslidar]

Although now day's with computers doubling in speed roughly every two years. You can take that 24 hrs and cut it in half with a supercomputer. Meaning Digital encryption on the level they are using against us, is now useless. To a major country's miliatry or extremist group with money to back a operation dedicated to harming us. So my point is, "what's the point in wasting tax payers hard earned dollars." For a system that can be cracked every 12 hrs or possibly less.

[CryptoDriver]

Go to TruTV's website and watch the video of a wanted pedophile 18 wheel trucker who had a scanner and used it to avoid where they laid spike strips and nearly killed both officers and civilians because of his ability to keep running based on the info he got from the scanner. Since there is no way to lock out only criminals, everybody has to suffer.

[alpinestarslidar]

I don't get why cracking digital encryption is so hard to beleive. All it is, is another form of digital protocol. Just like regular digital scanner tansmissions you hear are a standard protocol they have to be or else communications with each other would be very limited. As for how the 14yr old cracked it in croatia, they used a super computer 10yrs ago and it took 24hrs roughly to crack the digital encryption. Although by then it's typically rekeyed anyhow.

[RayAir1]

I hate encryption. I miss the days when only the feds had encryption because it was too expensive for town cops.

[alpinestarslidar]

X2, although I miss the day's more when they used Low band. 39mhz region. Those radio's worked great too, and back then there was no encryption whatsoever. If they just used the VHF system i'd be happy. That system works perfectly fine. If it didn't ham's wouldn't be refusing to use digital due to fade out's and drop out's and keeping their old analog systems in the VHF bandwidth primarily.

[alpinestarslidar]

Our founding forefathers of this country would be in utter outrage at this. They felt we had to right and it was our "duty" to monitor our gov.

[BubbyandKierra]

I agree with every bit that you are saying. And what was wrong with just having analog too. These local cops are spending OUR, THE PEOPLES, MONEY on upgrading these systems to digital. Thousands of OUR MONEY. I think people need to wake up and start taking a stand. And I know we're talking about scanners here but it works on a lot of subjects. We are slowly getting our rights and money taken away from us.

[alpinestarslidar]

x2 i agree. I couldn't agree more.  Thankyou for your comment and getting the intent of this film. Your comment is much appriciated.

Alpine-

[alpinestarslidar]

This gentlemen is the smartest man i've ever met on youtube, and i'd like to thank you and shake your hand for your intelligence. Also i'd like to shake your hand for getting the, "Purpose" of this film. Incredible Gentlemen. Take care where ever you may reside.

[CryptoDriver]

You can still "monitor" through FOIA... Just not in real time. Sorry, by the nature of their job, the police have things that are "need to know" and can't be released until a later time.

[Dusty696969]

I hate the whole encryption problem but Id be fine with listening to it later like 20 or 30 minutes delays as long as i can hear it all.

[alpinestarslidar]

Yet, we the people are always, "suspicious." Big lol. I find it suspicious that something this stupid need's to be encrypted from the Public eye? Why are we not allowed to monitor our own gov? What's the big secret? That's my question?

[CryptoDriver]

So what, you think the cops should also have to talk only over open air? You think they shouldn't be allowed to use cell phones? Sorry, police officers have a right to privacy, just because they are government employees doesn't open up EVERY facet of their day and communication to the public.

[alpinestarslidar]

A 14yr old in Croatia cracked this type of encrytion roughly 10yrs ago. Although in the USA cracking this encryption would be illegal, modifying a scanner to receive encrypted signals is illegal, and they don't sell ones that are even capable, and infact uniden purposely says on a label on their scanners, that they build them so they are unmodifiable to pick up such transmissions anyway. The cops even had your freedom of information act altered so that they could send "secretive" messages.

[RayAir1]

Yeah right, he probably cracked voice inversion.

[zoltan656]

I never heard about 14 year old cracked digital encryption in Croatia and I live in Croatia do you have any links to that story???

[swedishvolvo]

Why would he encrypt his transmissions? Anyway to crack it?
