I like to call my proposed solution the PATRIOT phone. It will look like this. It will feature RSA cryptography that is all but impossible to break, with no back doors or key escrow. With the right marketing strategy, a satisfactory product, and reasonable price points, it shouldn't be difficult to put such devices in the hands of several thousands of users. At that point, the device becomes an impediment to large scale surveillance. If even 1% of network traffic were encrypted, it would be impossible to capture that volume of traffic for cryptanalysis -- there simply aren't enough supercomputers.

Such consumer technology does not exist. There are a variety of phones that employ RSA or similarly strong encryption, but they are not interoperable and cost $1500 or more. This is puzzling. Crytographic algorithms, qua algorithms, are not patentable subject matter and cannot be monopolized. To whatever extent such monopolization was possible (i.e. by patenting cryptographic math done "on a computer" or "a microchip that performs cryptographic math"), those patents should have long since been expired. See 1, 2. This academic paper suggests a means for implementing RSA into programmable logic chips that cost less than $10, and provides sufficient computing power to encrypt voice data in real time. In fact, that paper is five years old: the technology should be trivial at this point.

*Outline -Form of a solution: the device. *Why doesn't it exist? Supply side: -firmware/chipsets patented... scale? -regulatory issues -lack of competition/barriers to entry *How else might it be implemented -the network? skype, google voice... -or private routers and a mesh grid *Legislative or regulatory response?

Work in progress, nowhere near done.
