Russians Order Mobile Phone Encryption Removed 302

Posted by simoniker from the static-still-encrypts-messages dept.
PenguinRadio writes "The Moscow Times is reporting that Russian security officers (The FSB, formerly the KGB) ordered all mobile phone providers to switch off their encryption systems for 24 hours, so the police could eavesdrop on all calls. An alert, either an exclamation point or an unlocked padlock, was sent to the phones in question. This is the second time such an order was given - the last time was after the hostage crisis involving Chechnya fighters in a Moscow theater. At least the Russian has the courtesy to warn all their phone users that this was going on. Not sure what the standard FBI procedure is on something like this..."

      It also lists that: "In 2002, no federal wiretap reports indicated that encryption was encountered. State and local jurisdictions reported that encryption was encountered in 16 wiretaps terminated in 2002; however, in none of these cases was encryption reported to have prevented law enforcement officials from obtaining the plain text of communications intercepted. In addition, state and local jurisdictions reported that encryption was encountered in 18 wiretaps that were terminated in calendar year 2001 or earlier, but were reported for the first time in 2002; in none of these cases did encryption prevent access to the plain text of communications intercepted.

      The session key used by the A5 cipher in the GSM standard is 64 bits. Interestingly, ten of those bits are not used. Suspicious people have claimed that the key length was reduced to facilitate eavesdropping. Carriers hotly deny this (http://jya.com/gsm042098.txt).

      Looking at it from first principles, there'd be little reason to disable encryption for a single user. Law enforcement could tap the phone network downstream of the tower, and intelligence services would want to listen to everybody. (I'm speculating 'cause I don't know).

        The difference is the general level of hassle and red tape, as well as accountability. Of course if you're up there in intelligence I'm sure you can unaccountably "tap" the land phone network at will using more advanced systems (Echelon and whatever's come since come to mind) - but if you're just part of some FBI field office trying to handle an immediate situation akin to the Chechnya incident the landline option means you have to get authorization and go on record for doing it, and you have to be precise about what you're tapping, and you could be delayed by all the BS. If you can tap the airwaves easily (supposing you have a laptop that can crack the effectively 54-bit encryption of a GSM call on the air), you can do it without the fuss and without being accountable.

        Don't forget also that finding the right landline call to tap might be a needle in a haystack problem, but finding the right cellular call can be fairly easy if you're on-site near the caller, since you can just look for strong enough signal strength to be within a given radius of you physically, and furthermore even triangulate the signals' positions.

        Good info on GSM technology in that link. I've always had a preference for GSM over the competing standards. It's always seemed like a more elegant solution, especially when it comes to using SIMs.

        Seemed for quite a while that GSM was going to die in Canada, but with two networks now, we're going pretty strong. With the exception of the first (analog) phone I bought, everything else has been GSM and I love the convenience of just moving my SIM from phone to phone and never having to call the company to register a handset, transfer details, worry about programming, etc.

        As posted, the GSM encryption is more than secure enough to stop casual evesdropping. It wouldn't stop law enforcement or government for long, but they can always just monitor at the cell cite, or have the service provider archive the data stream from suspect handsets anyway.

        By contrast, my 900mhz cordless phone at home has absolutely no encryption and could be monitored (albiet at short range) by anyone with a scanner. Consequently, I'd rather use the cell for talking to banks, making purchases with credit cards, etc.

      • There are two versions of A5: with full 64bit (for US, Germany etc) key and 54bit key (For Russia, Latvia, China etc).

        Two months ago I requested my GSM company about their encryption technology. They replied: "Yes, we use good encryption. No, we cannot tell you which exactly".

    The only thing GSM encryption prevents is eavesdropping on GSM calls with radio receivers. Law enforcement can still wiretap where the GSM call hits the copper, after all the call has to be decrypted by the phone network.

    I don't really see why they'd have to do this, technically.

    Perhaps they just wanted to "appease" the public by showing them that they are invading their privacy to search for Chechyen terrorists? After all, this is pretty visible.

      Technically, GSM networks are quite hard to tap in the conventional sense because the way that the switches are interconnected and the calls bounce around between BSEs. Essentially, monitoring GSM requires extra software, that even in Western countries, is only being grudgingly installed by the networks.

      Also, to activate the tap requires the cooperation of the network. This means a nasty trail of paperwork and inconvenient things like warrants. This is fine when you are chasing Chechnyans, but awefully inconvenient when all you want to do is to place a squeeze on an oligarch.

    The true purpose of this action is any one of the following in order of highest to lowest probability:

    1) Draw public attention to the bombing/terrorist act and drum up support for whatever it is the government is planning next. Good way to do it as anyone and their dog carries a cell phone. Bad way to really tap conversations since now everyone knows they are being tapped.

    3) Put the terrorists/chechens/whoever on the run - scare them etc. This sure is a big dynamite in a small pond though - so i doubt it.

    Funny, this reminds me of a joke that a Russian friend told me...

    Both of us are of the age that we grew up during the Cold War and remember what it was like having nukes pointed at each other day and night...

    Anyway, we were on the phone and the connection was really bad. At one point, we heard a click similar to someone picking up the phone. So, Dmitri paused and said, "Wait a second..." After a few seconds, he began to speak again and I asked what had happened. He explained that, in Russian, it is considered polite to pause the conversation when you hear the FSB changing the tapes recording your conversation. :)

    I laughed my ass off.... Yes, people, I'm now ass-less....

    There is no need to turn off the encryption to listen in on calls. They can just use the Lawful Intercept feature which is a built-in in all mobile phone networks. All they need (in most countries) is a court order to enable it. I appreciate that turning off encryption on all calls would enable them to listen in to the calls much more easily, but honestly, how much manpower have they allocated to deal with the tapping of all these phones in that 24 hour window? Do they REALLY believe that this aids them in their investigative efforts?
