FCC Affirms VoIP Must Allow Snooping 301

Posted by CowboyNeal from the big-brother-is-listening dept.
MarsGov writes "The FCC released an order yesterday that requires all broadband providers and all "interconnected" VoIP providers to implement CALEA — in other words, law enforcement can snoop on your online conversations, both voice and text. While this is no surprise, it makes encryption for VoIP even more urgent."

      If Skype bows to FCC pressure (which they will) then they will not provide encryption in their service which means that the people using Skype won't be able to encrypt their calls.

    Encryption for VOIP won't help in many scenarios that LEAs are interested in. If you're calling a land line from your VOIP connection, the end point on the land line won't be able to decrypt the conversation, so even if all of the VOIP traffic is encrypted you'll have to go to the PSTN in the clear. AIUI, that's what they mean by "interconnected".

On the other hand, analysing the call graph [wikipedia.org] is quite tractable and completely orthogonal to the content. Enryption won't protect you from the government knowing who you're taking to!

        With all the talk of Bush authorizing international wire-taps on US-to-non-US citizens, it came up that the most probably reason the NSA is involved (see the current case EFF vs ATT) is that the NSA's Echelon system does have the throughput to handle that kind of workload. That Echelon was initially designed to snoop on purely international traffic, but it is just as easily turned on US citizens if the right (or wrong) person wants it to be so.

        Just from an algorithmic viewpoint - that kind of workload is going to fall in the "embarrasingly parallel" group which means you can just keep adding PCs to scale-up to a volume of phone calls that is limited only by floorspace and electricity.

        • Not Tor as it's currently implemented, no. I think the latency is way too high, even under ideal conditions (something that's perceptibly slow for HTTP traffic isn't going to fly with SIP packets). However that doesn't mean that you couldn't, at some point in the future -- maybe today -- set up something Tor-like for voice. The problem would be finding enough high speed and low-latency nodes to provide any real security, while also not injecting tons of latency into the call.

        That ethos is actually something that's been in use for quite some time by seemingly many groups, somewhat under our collective noses, Numbers Stations, [wikipedia.org] shortwave radio transmissions with origin unknown that transmit codes of numbers or letters, repeat a few times, then disappear. Most likely they are for undercover operatives with a codebook.

        The idea is that it's tough to track their origin (apart from perhaps the language of some of the short messages that accompany them, but even that could be a red herring) and it's impossible to track down who's recieving it. Also, if it's using a one-use key decoding system, it's impossible to decrypt a meaning from it. Finally, most of these stations reappear at regular intervals, there's no real way to tell if one day's message is "all clear" or if it's "commence with the plan tomorrow."

    If you trust the government not to abuse this, then consider whether you trust the government to be able to effectively safeguard access to this. Ignoring social engineering (e.g. $), how likely is the government to have every bit of this infrastructure protected against stealthful 3rd party break-ins?

    Suddenly blackmail is going to get a lot easier.

    It took many decades for the Internet to flower and change the world with its freedoms. It is taking far less for the governments of the world to deflower the Internet and sow the seeds of thought control.
    • I know it is bad form to reply to one's own post, but I would like to point to the "Clinton era" encryption strategy with a (faulty) back door. That was the "clipper chip", and you can read about it here. [wikipedia.org]

      The point is ... whatever the backdoor mechanism the government mandates, it will be vulnerable to third-party abuse.

  • Nothing like a group of a few poweful men enforcing their whim on us, ensuring that they can continue to stay in control over the masses. Passing laws, rules, regulations, and restricitons that pretty much none of us want, without consulting us, and barely even informing us.

    Can't you just smell that freedom?

    Can we please quit voting for the establishment now? Please? With a cherry? For the children?

    Properly implemented, SIP (common VoIP protocol) works like this:
    A='A Party' - the person making the call
    B='B Party' - the person receiving the call
    P='Proxy' - the VoIP provider

    A and B register with P.
    A makes a call to B:
    . A requests P that it be put through to B
    . P contacts B, B's phone rings
    . B answers
    . P lets A know B's details
    . P lets B know A's details
    . A and B exchange voice traffic directly, without involving P

    This allows latency to remain low when, say, A and B are in Australia and P is on the other side of the world.

    To perform a successful wire tap in this scenario, the FCC would need to intercept the data at multiple points, possibly in separate countries.

    Alternatively, P can tell A and B that there is too much firewalling in place and that all voice traffic must go via P, but by doing this they are giving the game away... it would be easily detectable by A and or B if they were smart enough to know what was going on.

    • First of all, you don't want to attack the strong links when there are weak links that'll get what you need. A Wiretap is a 3-Way-Call with the Univited Party on Mute. So you don't try to break the cryto, you try to make sure you're on the call.

      SIP Control Support for Encryption is Limited. There are two main kinds of encryption used in SIP - call setup messages, which can be implemented using TLS (SSL's successor) or left unencrypted, and media channel encryption, which is done end-to-end by the calle

    That's okay. Usually when I plan my terrorist attacks, I don't use VoIP. It pays to just have a spoke wheel conspiracy like we used for the September 11th attacks. That way all communication is done through personal meetings and few people know enough of the plan for it to get leaked even if one of our members is busted.

    In fact I am quite happy to see this new FCC order. Don't forget our goals with September 11th was to break America down and give politicians reasons to take the freedoms away from the publi

  • Use IP to IP Dialing To Bypass VOIP Backdoors (Score:5, Interesting)

    by Junior Samples ( 550792 ) on Thursday May 04, 2006 @11:54PM (#15268364)

    I regularly use VOIP via Free World Dialup (FWD). This system uses the SIP protocol. FWD servers seem to have frequent outages. To get around this problem, I've found that I can use direct IP to IP dialing and bypass FWD's servers completely. IP dialing is cumbersome, but you can put the dialed addresses in a speed call list and use 2-digit dialing. This works very well. There's a side benefit of no call logging since the provider's server is being bypassed. In theory I can call any SIP phone that's connected to the internet whether they're on Vonage, Packet Eight, or any other network, if I know their IP address.

    Right now there are about a half dozen members of our private network. We're all registered with dyndns.org to solve the problem of dynamic addressing. We're all using Sipura Network adapters to connect a regular telephone to the Internet. The Sipura adapters accommodate dialing by hostname or IP address. The latency is lower with direct IP dialing because the voice packets are not routed through FWD's STUN or NAT servers.

    This method is more secure since you're not dependent on any VOIP provider. The back doors that they provide for government spying can be bypassed. Encryption would be difficult but not impossible because it would have to be implemented in the Sipura firmware. SIP software phones will also work with direct IP dialing.

    where this is any different then the cops being allowed to tap regular telephones? Seriously, have they once said that the cops will have unfettered access to this information without a warrant? If not, then I do not see why there is this urgent need for encryption on VoIP. I mean we are talking about the police agencies being able to have the same access to listen to VoIP conversations that they already have to tap every other phone line in America.

    Now, I am sure you are all wearing your tin foil caps, but really this is not about some great big brother monitoring scheme. If you are so scared about people listening to your calls, you do not need encryption. Just start talking in code. Afterall, mobsters and just about anyone else committing illegal activity have been doing it for years to avoid being overheard.

    I just am afraid I do not see everyone elses great concern in this matter. Of course, my lack of VoIP means that monitoring my calls is already quiet within the realm of possibility. As for the text conversation part, if I were truly concerned about stuff I was saying the last way I would transmit it would be over IM or through e-mail.
