Zimmermann's Silent Circle Now Live 127

e065c8515d206cb0e190 writes "Several websites have announced the launch of Silent Circle, PGP's founder Phil Zimmermann's new suite of tools for the paranoid. After a first day glitch with a late approval of their iOS app, the website seems to now accept subscriptions. Have any slashdotters subscribed? What does SilentCircle provide that previous applications didn't have?"

    The "Silent Circle" uses their own "Silent Network", allowing centralized user tracking. Also, the code isn't open source, so you have no idea if the crypto key generation is any good or if there are backdoors.

        Considering Zimmermann's track record of not including backdoors and that he was investigated for several years much to his personal detriment for several years in the 90s for his release of PGP I think this particular protocol is pretty safe. Lastly and business case is based 100% on total security. If ever it leaked that there's any kind of backdoor it would all be for naught. I highly doubt the core team (there are 4 of them, including Zimmermann, 2 ex seals, and Callas) would risk their reputations on including a backdoor. In addition any real backdoors would flag an interference.
        • Regardless of their reputation, a central server will always put you at risk. There are lots of bad people out there with squeaky clean reputations, but we only find out when they slip up.

            Even if the endpoints encrypt data, encrypted data going through one central point is still at risk. Even though it can't be read, it can be tampered with, possibly DoS-ed. At the minimum, an attacker can eventually do traffic analysis and figure out who is communicating to whom.

        That's funny, because I almost feel the complete opposite way. I really want to trust Zimmerman, but I can't make myself do it. Part of it is keeping his work closed source, which is extra scary when talking about cryptography. Being asked to trust a security solution that you can't examine is insane.

        But part of it also comes from his past. He went against the wishes of the US government and won. In my experience, that just doesn't happen... ever. The fact that he's still working in cryptography and not in some hole somewhere makes me think he's playing ball with the government. It at least raises doubts, which cannot be alleviated by reviewing the source code.

        Or maybe I'm just paranoid. But cryptography is the plaything of the paranoid, and relying on the paranoid to just trust you seems a little off.

            "But why trust the skilled individuals?", you may ask. Answer: because I find it unlikely that all the world's cryptographers are conspiring to keep quiet about any vulnerabilities they find the code. At any rate it's a more sensible strategy than "assume that Zimmerman is both infallible and incorruptible".

              Yes. Let me just add a nitpick. It is necessary that *any* user can *initiate* an independent audit of the code he personally received.

              Merely trusting a community of experts who choose to publish their audits as they please is another form of argument from authority. It's a slippery slope to a world where the source code is only available to qualified experts, since there would be no point in making it available to nonqualified individuals.

              Instead, the point of open source is that any user can hire an expert of their choosing, to work on source code as given to them (not source code the expert downloaded from a presumably equivalent source). AND THE PROBABILITY THAT SOME USERS ACTUALLY DO SO MUST BE STRICTLY POSITIVE.

              because I find it unlikely that all the world's cryptographers are conspiring to keep quiet about any vulnerabilities they find the code.

              Like nearly everybody, cryptographers tend to act in the best interests of their employers. That is why it is necessary for random users to hire such cryptographers every once in a while, as outlined above.

              We cannot trust that the usual employers won't keep quiet about the findings for selfish reasons, eg large companies like Microsoft or Google sitting on discoveries until they can create and deploy a patch.

I do NOT mean this in a religious sense, any way shape or form. At the time (this was the 1980's) he spoke a lot (incessantly?) about the danger of nuclear war and all these bombs we've got. I expect that this same incredible focus and sense of purpose has now been applied to security, which could be a really good thing. I also expect that he has mellowed a bit, but that's just a guess.

    I wrote to Silent Circle over a week ago when news of the impending launch first started making circles.

    SC's COO was kind to respond in an attempt to allay my fears. Sadly though his answer was more "non" than one.

    A week ago replied back with a follow-up question, and have yet to receive a response.

    While my political activism is pretty much limited to change.org petitions, SC is directly marketing their services TO activists. As the Occupy movement has shown, political activism, and the free-speech that goes along with it, are becoming in jeopardy. My concern, and I feel it's a valid one, is that CALEA will give subscribers a false sense of security. After all when Microsoft purchased Skype, one of the first things they did (they had no choice) was to install CALEA intercepts.

    Hopefully somebody at Silent Circle will be able to answer this. Until then, I wouldn't recommend it. Check out The Guardian Project and Jitsi instead.

    Of late I've been thinking that it might be prudent to establish an on-line persona that can't be traced back to me. Between corporate tracking (Google?) and government's love of surveillance, and a sense that we could be heading for some economically or politically charged time, I can see situations where anonymity could be essential.

    It seems to me that if you can start with an untraceable e-mail address and consistent use of Tor, you should be on the way to building up an on-line profile that's recognizable, useful, and fairly disconnected from real life.

    I'm not naive enough to think that anything I could do would be 100% safe or secure, but surely you can keep most of the prying eyes away from you.

      "might be prudent to establish an on-line persona that can't be traced"

      It would be prudent for everyone to do so. And everyone should encrypt every communication possible.

      The simple reason is that if only 1% seek privacy, then governments and others can simply focus their great power on that 1%; but when everyone seeks privacy it is more difficult to snoop on any particular 1%.

      Yes, it will be harder to pin down bad guys & terrorists, but that's the wrong approach anyway. When people are educated, treate

      With version number, installed add-ons and what information is available about your particular hardware, it's quite possible to figure out which personas belong together.

      It's not just about a particular id bit any longer, it's tiny bits of irrelevance scooped up by tracker networks combined into a whole in the long term.

  • I'm personally surprised that no one has bothered to build encryption in to the TCP/IP stack yet, an sTCP/IP if you will. Using a public/private key encryption model, each time the stack initiates a new connection to any IP, it would first ask the other side if it supports secure encryption, if it doesn't, the other side would probably return an error. Once it is determined the other side supports encryption, both sides generate one-time key pairs and transmits the public key to the other side. Once the con

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
