Feds' Radios Have Significant Security Flaws
OverTheGeicoE writes "The Wall Street Journal has a story describing how the portable radios used by many federal law enforcement agents have major security flaws that allow for easy eavesdropping and jamming. Details are in a new study being released today (PDF). The authors of the study were able to intercept hundreds of hours of sensitive traffic inadvertently sent without encryption over the past two years. They also describe how a texting toy targeted at teenage girls can be modified to jam transmissions from the affected radios, either encrypted or not."
You notice that pretty much everything sold to the federal government is fraudulent? There is an entire industry devoted to ripping them off. Why isn't there a mechanism in place to punish these folks?

or supposed to be. I couldn't find where they where using an encrypted channels.
And it's radio, so NEWSFLASH: It can be jammed.

The front page of the 'texting toy' website begins with 'It sounds 2good2btru - but it's 4real!' and ends with my stomach contents, evacuated onto the floor. Shame on TheGeicoE for subjecting us to that.

I'm totally lost here; want to try again?
Uh. Yeah. I think FCC rules prohibit encryption.
They do not.
And we are talking about radio, not wired communications.
Security issues in radio and wired communications are almost the same unless you can guarantee no physical access to your wire.
You want privacy? Use a phone.
Phones are radios.
The FCC prohibits encryption of radio waves? So...does that mean my WPA2 access point is in violation of the FCC?
:(){
And it is legal to listen in on them. Google for "police scanner".
Now I could see reasons why the FBI might have encrypted radios, but then again they also might decide such a thing isn't necessary, or that they should be selectable.
Either way, the idea of unencrypted police radio isn't surprising, it is the norm. That may change, but for now in most places a cheap scanner is all you need to listen to police radio, if you wish to do so.
try frequency hopping, or spread spectrum technology, no analog or digital scanner can receive them...

Back in the day, you could tune into the police on an ordinary FM radio (in the UK). They used the frequencies from 100 to 108 MHz before they got moved.
Uh. Yeah. I think FCC rules prohibit encryption
There's no overall ban on encryption, although some services such as amateur (Ham) radio aren't allowed to use it.
Is their some reason the feds are not using the same radios the military uses? I'm sure the DOD has some experience in secure portable communications.
Traditionally, all police radio communications were unencrypted and anybody could buy a scanner from RadioShack to listen in. My understanding is that the press commonly used them and would publish what they learnt from it. And that was a good thing, because it forced the police to be a little more accountable.
You can't do encryption over HAM waves because it is supposed to be free and open to all that qualify, not a place for exclusivity. Also they want to be able to monitor to make sure people aren't using it for commercial purposes.
However on other bands, encryption is just fine. You really think the military uses unencrypted radio for all their communications?
For that matter, your cell phone is encrypted. Grated it isn't very good encryption, but it is encrypted. All digital cell phones are.
Try googling "spread spectrum" communications.
With spread spectrum technologies, you can transmit damn near anything covertly.
If the snooper does not have your exact algorithm, not only does he has no way of decoding your transmission, he doesn't even know a transmission took place.
Yes, spread spectrum can be jammed if a wideband noise source is placed near the receiver. The S/N drops so much the receiver will fail to extricate the signal from the ambient noise.
A spark gap is a wideband noise generator.

The changeover started pre 9/11, but the influx of Federal funds after that really kicked it into high gear. All or nearly all major metro areas now use digital, encryptable radio systems and they're spreading to smaller and smaller counties and cities. And thanks to the Publc Safety push they're using the P25 standard for interoperability.
It has made it much harder for journalists to learn about news-worthy incidents.
The prevent encryption on public bands. (CB, HAM, shortwave)
They also describe how a texting toy targeted at teenage girls can be modified to jam transmissions from the affected radios, either encrypted or not."
A texting toy targeted at teenage twats 'twas transformed to twist transmissions 'tween totalitarian terrorist-tackling tards.

"transmitting a 100ms pulse"
You want to try that again?
Well, more like a typo, meant to type "10ms", noticed that it after I posted, but didn't think it warranted a correction, since it doesn't change the basic premise of my post.
But thanks for the correction, you've added a lot of value to my post, Anonymous Coward!
Software or hardware to filter the signal from the noise can help in a jamming environment but it's not a cure-all.
Unless you can stop the jammer from transmitting, stop your receiver from picking up the jamming signal, or you can simply overpower him, it's hard to stop a jammer.
For typical hand-held and automobile radios there isn't a good solution.
The most effective way to stop a jammer usually involves either finding and arresting the person responsible or destroying the transmitter. Sometimes a credible threat to do either will work as well.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
I've always wondered about wholly passive methods for police activity monitoring. For example, how difficult would it be to combine a GPS position fix and a DF setup to track nearby police cars or foot patrols? That's assuming law enforcement and emergency services use dedicated radio bands for communication. I guess eavesdropping would provide further information, but even just a position fix could be useful in the commission of a crime.
