I nearly forgot to mention this really great project by Harald and friends: http://gmr.osmocom.org/trac/ To quote his page entirely: "This is the homepage of the Osmocom sub-project GEO Mobile Radio. It is collecting information and software related to the ETSI GEO Mobile Radio specification and its practical implementations like the Thuraya satellite phone network GEO Mobile Radio is a set of specifications describing a satellite based mobile phone network. Radio aspects It uses the L-band frequencies 1634 to 1656 MHz (earth to space) and 1532.5 to 1554.5 MHz (space to earth) for communication between mobile phones and the respective satellites. The polarization is circular (left) and the modulation is pi/4 QPSK, using a channel spacing of 31.25 kHz" Here's a guide for doing your own Thuraya interception: http://gmr.osmocom.org/trac/wiki/Receiver_Setup All the best, Jacob _______________________________________________ liberationtech mailing list liberationtech(a)lists.stanford.edu Should you need to change your subscription options, please go to: https://mailman.stanford.edu/mailman/listinfo/liberationtech If you would like to receive a daily digest, click "yes" (once you click above) next to "would you like to receive list mail batched in a daily digest?"

Really close to what I had in mind, and I plan on using Ed25519. This is actually an approach that forces you to do more than take a fleeing glance at a given user's public key thumbprint/ID and I feel that's missing from many similar systems (e.g. OTR) > People could also associate various metadata with their public key in a > very similar way > to how they do with PGP keys: with metadata packets signed by themselves > and other people, thus establishing a web of trust that would enable > search, the same way we can reliably search for PGP keys but with an > easier-to-use interface that will always show someone's relationship to > your current trusted contacts. > My goal was to collect metadata about content transfers in the system by having all participants in file transfers sign a client-specific long chain which serves as a record of who has transferred what. Through the course of normal system operation any given peer will collect a number of these long chains, which can be run through a collaborative filtering algorithm (e.g. singular value decomposition) in order to make an educated guess about the properties of peers you've never interacted with based on their collective similarity to peers you have interacted with directly.

This allows you to set up secure channels which are based on the same identities as the other signatures in the system.

Good piece, I have been following such developments from a distance for some time, and in fact I won a journalism award for a piece I composed four years ago on this subject. One begins to understand if not approve the actions of moralistic atomic traitors like Ted Hall who gave away atomic secrets because they sincerely believed that no one nation should command such power. Unless one believes that the intentions of the current and future conservative administrations in Washington are wholly benign in the developing world, one cannot but shudder to contemplate Robocop writ large. For those for whom the power motive is paramount the thought of such weapons systems must be as intoxicating as a blast of methamphetamine. For not only can military omniscience provide the basis for annihilating force projection against foreign insurgents, it can offer the means of utterly neutralizing principled political opposition at home. That such technology will not be used in that matter is hardly certain in the light of recent NSA abuses. There is however, some reason to believe that the nation may be roused from this particular wet dream before reaching climax. The manufacture of semiconductors has already fled abroad to nations not disposed to favor such an expansion of U.S. military capabilities, and increasingly the design of semiconductors is fleeing to the same places. The relatively small size of the U.S. engineering community compared to those of certain Asian nations might also work against such a profound military asymmetry ultimately occurring. In other words, the U.S. might be losing the technology base to support such a grand scheme. Imagine if a Dominion Theology regime ascended to power in Washington and thought to utilize armies of Golem against the infidel. The ironies are profound.
