There is a SECURE Messaging System designed specifically for Prep'ers that is being fielded for just this kind of senerio.... It is called MonkeyNet, and is associated with
[url=http://www.survivalmonkey.com[[/url]. The Technology is ALL Open Source and Available to ANYONE who has an interest in SECURE Messaging.
I wrote a Secure Messaging White Paper that covers the Technology, and Implementation, of the technology, that was published back in October 2011. It is attached here. This system does NOT focus on the Hardware Layer, but only focuses on the SECURE Messaging, as we, basically, have NO Idea, what Comms Links will be available, in any SHTF Senerios. So the idea was, to have a common Technology, spread throughout the Prep'er Communities, that would allow them to decide, with who, and when, to build a SECURE Communications Link. This technology allows for separate Groups, to have their own internal SECURE Messaging, and should they find the need to have SECURE Messaging with outside Groups, they can exchange PADs, and KeySets, that will allow for SECURE Comm Links without compromising their already setup, Internal SECURE Messaging Systems. There is nothing about the technology that must be held "Close" except the Generated PADs, and KeySets, common to both ends of the SECURE Comms Link. The technology can be distributed and used by anyone, without compromising anyone else's SECURE Messaging System. We have published the technology to Off-shore Servers, (Bit torrent, and others) so that it can't be deleted by ANY Government, Anywhere. Our Network is in Beta Testing now, and we hope to roll it out to our Vetted Members, this summer. Anyone can setup there own Network, as they may find need. I will be more than happy to work with ANYONE, who has an interest in building their own SECURE Messaging Network. Just ask... Just Say'en.... YMMV....
