A while back, Eric Blossom posted a URL for a mass-market, phone encyrption device (http://www.comsec.com/). The point of this post is to posit a
The above mentioned crypto phone was incredibly expensive, if I remember correctly. What it basically was (Please keep in mind I may be thinking of a different product) a box containing a modem and a crypto-crunching CPU. Phone in one end, processed by said CPU, and send out other end. I have/had a similar idea, but I want to try make it a totally software product (assuming you have the necessary hw requirements on your computer) where you talk in through a microphone (can something be wired so you can use a regular phone plugged into your computer/modem/soundcard???) your CPU crunches code, and spits out the encrypted data. Obviously, the complementing steps would be done on the receiving end. Has anyone ever tried anything like this?
I think we need to keep a couple of goals in mind. The first, is to get encrypting phones (or phone add-ons) into Wal-mart, K-mart, etc (where probably most Americans now buy their phones). The prices need to be low enough that people will want to buy them (<$100?). Is this technically feasible? The comsec device from the above URL already demonstrates the needed capability. Is the cost target possible? My guess is soon, given the lowering costs and increasing capabilities of current processors.
Goals sound good. I feel it *definately* has to be below $100. Personally, I use a phone bought at K-Mart that cost $12 _after_ tax... I wouldn't mind paying $50 for a techno gizmo that made my conversations, inane as they may be, private. The price would also have to be low to assure the other end has a similar techno-gizmo, or I would have wasted my money. Anyone else see the *immediate* need for a standard?
The second goal needs to be to push a similar product for cell-phones.
If I'm not mistaken (and I've been known to be from time to time :-), cell phones are already encrypted between the phone and cell tower. That way, they are no less private than a regular phone. Of course, you may be referring to further end-to-end encryption built into the phone in addition to this, but as far as they being less secure than a house phone, I'm not sure about that one.
Given that these goals are met, I think widespread use of crypto over phone lines would become almost inevitable. However, the fun part would be the introduction of such products. The FUD coming from police, the government, etc. would be amazing to behold.
Agreed!
