One time pads, as long as the “pads” remain secure, simply cannot be broken. Therein lies the trick though, getting sufficiently large pads (ie. files of random data) securely in both (all) parties hands and keeping them secure. There are some relatively simple procedures for this, but not necessarily easy/convenient procedures...
The beauty of the system I described is that it allows digital transmission. . . and it is still secure. You can also send the same message to multiple recipients so long as they all have the same book, rules, and calendar. Only the recipients can decode it. . . and since it never repeats for character, word, or apparent message, it is totally un-decypherable.
Strict one time pads I imagine are used only for high profile singular comm requirements.
Swordmakers idea eliminates the hard copy pad distribution without the pseudo random number generation of the past, as I gather that new methods approach truly random numbers now.
The San Bernardino shooters apartment had an interesting object. The wall hanging Islamic rug/tapestry.
At first I thought the matrix of the field was a repeating graphic of small diagonals, but a closer look reveals Arabic script that appears to vary. Add the comings and goings of strangers to the apart. How could one be sure of the identity of another agent? The rug has a matrix. of usable 200 cells, with and without script. I subtracted the central image.
It can then be used as a one time pad or point and speak a specific cell or series of cells , the locations set by any factor. Can also reference specific suryas of the Q'ran which have meaning.
Started thinking that using a matrix that has the identical symbol in each cell, that maybe a pad can be created. Taking the star field of the US flag as an example of identical symbols to which various cultural attributes might be ascribed, in this case order of admission, dates etc.
A poor example, I know, but fun to think about.
That's an interesting observation. It could indeed be a key for using a system similar to mine for passing coded messages. Each could be a passage in the Qu'ran which then indicates the starting page. Row and column indicate direction rules for the code number counts. Easy. . . and right in plain site.
...in plain sight...with no paper or transmission trail.
Controller verbal->messenger->agent->point and say or die.
That’s kind of interesting.
Not being picky or anything, but I count 198 cells, with or without the arabic text...not counting the top, larger, text or the central image. Who knows, might make a difference.
That was meant to be 196.
Working from the blurry photo, counted 8 across, 29 down, included blank ‘cells’; 29x8=232
Minus 4x8 center=32
Bi-focals and phone image could effect my count.
Showing my work, not that our count difference affects the general concept of the matrix
Yeah, it really doesn’t matter for the concept, only if one were trying to actually decipher. Interesting idea.
"Black-bag" decryption" -- being sneaky and using subterfuge rather than high-tech to gain the password.These techniques are sufficient for all legally authorized government surveillance (most notably, someone refusing to provide files after being presented with a warrant can be held for contempt of court, which I suppose would be considered an example of a lawful "rubber hose" option).
"Rubber-hose decryption" -- beating the crap out of people until they give up the password.
The Feds want to sweep this fact under the rug, because relying on these options keeps them constrained. Planting bugs, reconstructing messages from electromagnetic noise, etc requires investments in manpower and equipment, and holding people for contempt until they produce records is done in the public eye. Thus, they Feds are limited to picking and choosing actual suspects rather than spying on everybody. Well, too bad -- that's what they're supposed to be doing anyway.
