Best Handset For Freedom?

Father Thomas Dowd writes "The images we are seeing of Iran are being captured on cell phones and the text is being twittered over SMS. Still, the government has some control over the networks, and we are all familiar with fears of wiretap technologies to spy on users. If the cell phone is the new tool of freedom, what would the best 'freedom handset' contain? I'm thinking of a device with an open OS, where each phone could be a router for encrypted messages passed through Bluetooth/WiFi/whatever, thereby totally bypassing physical infrastructures when necessary. Of course, some sort of plausible deniability encryption a la Truecrypt would also be good, in case the secret police catch you with your phone. What else might we need?"

    First off, no commercial phone will come with encryption or any sort of privacy option. This means that you will either need add-on applications, or the ability to tweak the OS.

    Secondly, you need an OS you can audit. This rules out BlackBerry, iPhone, and the Nokia N line. Realistically, you're going to end up with a Linux phone.

    Thirdly, you need one that is well documented, with a vibrant developer and user community.

    With these criteria, I can recommend the T-Mobile G1. I compiled my own OS image, I can run whatever I want (I encrypt ALL data, messages, and calls), and none of it shared with the telcos or the government (one and the same at this point).

      I doubt that. If you had, you wouldn't be able to make phone calls on it. The GSM stack runs on its own processor core, has its own closed-source operating system shipped as a binary blob, cannot be upgraded without the encryption key that they won't give you, and for excellent regulatory reasons even if you did have the key, turning the radio on while running unauthorized firmware would get you beaten to death by lawyers.

      Sure, you can run your own code on the applications processor, but let's face it, any modern electronics device is full if little (and not-so-little) processors running lots of code that you have no access to. You simply have no idea what any of that stuff is doing. Auditing the code running on the apps processor is a start, but no more than a start.

      You tell everyone you want to talk to to set up a public key. Public keys can be put on the internet, anyone who wants to contact you can encrypt his message with the public key and you use the private key (generated at the same time as the public key), which you are keeping to yourself, to decrypt the messages.

      Right because that's what will build the sort of popular uprising that has overthrown numerous governments in the past (including the last Iranian form of government)... armed rebellion.

      There is nothing the Iranian government would love more right now than a bunch of armed self righteous knuckle draggers to start shooting police and militiamen. You instantly change it from a popular peaceful movement into a legitimate civil war and the Government has full authority to start fighting said war. The Iranian government is losing the respect of its people more and more every day due to its heavy handed over reaction to peaceful and unarmed civilians. But by all means break out the ol' Smith and Wesson and start shooting government officials. I'm certain the ensuing civil war will result in a peaceful and democratic government on top. Not a charismatic warlord.

      Soviet Union, Ukraine, India, Iran 1979... the list goes on and on of successful popular uprisings and bloodless transitions of power. It's often then violent transitions which result in unstable and repressive replacement regimes.

    As a dissident, the better choice would probably be a stolen phone! Going to jail for stealing a phone will get you simple prison time and probably a beating or two. Going to jail for spying and sending videos to Western Agents could get you disappeared. Having an openmoko phone would be highly suspicious from a technology point of view (although it would probably be easy enough to hide stuff in from a bunch of police thugs.)

    There are three parts to security: Confidentiality, Integrity and Availability, C.I.A. If the C part is most important, then a netbook with encryption and OS on removable storage makes sense. Availability isn't so good because you can't leave it on all the time to receive messages. Once the revolution has started, availability is more important because the government will be trying to shut down networks, and there is the element of hiding in plain sight if there are a hundred thousand other people in the crowd. In that case, adapt your plans to whatever communications you have left.

    And prepaid cards. For the love of God, don't forget to limit yourself to PREPAID cards. And, needless to say, buy them in reasonable quantities, not too large so the store clerk remembers you, not too small so they have 20 datapoints (shop locations) giving away your location. Buy them in different stores, but make sure your home is not right in the middle of those shop locations. Preferably limit yourself to shops lying in a single direction. Do not recharge the cards if you can avoid it. Communicate using SMS and keep that phone OFF except in secure locations (and the most secure location is within a crowd, say, in a movie theater). Preferably remove the battery alltogether. SMS'es will arive within a few seconds from turning on the phone, so turn it on in a crowd, receive the sms'es, send a response if necessary and turn it back off.

    Oh and, pay them cash. Long live cash for anonymity. Don't carry identification, even if that's illegal.

    Don't use an open source phone. There are so few they give search parties an easy reference point. The more popular the handset, the better. If you have a friend in the phone selling business, ask for the idiot's phone. Buy secondhand, and buy a new handset (with a new, unpredictable IMEI number) regularly. Sell the old one back, because if they are sold again, the buyer will present the authorities with an easy to find, but wrong, target. There are literally thousands of secondhand phone shops in Teheran, and none of those will bother to remember their customers. Especially street stands are good.

    Make sure you have another, regular phone, so that you have the option of dropping your "dissident phone" in a bin, without a search party wondering "hey why don't you have a phone". And carry some sort of hat and glasses, you'd be amazed how much they change your appearance, and it only takes 5 seconds to put them up.

    And if I were in Iran. I'd put on the women's police uniform with some 20 friends, those black clothes, they make you very hard to identify, and you can't really see if it's a man or woman inside, and attack isolated police officers in those clothes.

    You have got to be kidding me."Freedom Handset"?

    If people really want to change the situation they are in, they will find a way to communicate their ideas.

    The message is so much more important than the medium used to pass the message.

    The more "security features" you add to a device, the more difficult it is for the message to get out. You have to have a device to send your encoded messages, and whomever you are trying to communicate with needs a device to receive that message.

    I would think that the less complicated you can make the delivery of the message, the better the chance of your message making it to the people that you want to hear it.

    The real "Freedom Handset" should be a Bull-Horn.
