.@savagejen There's one universal feature of space opera: cryptography is mysteriously a lost technology. B5 was even worse.

@bascule@puellavulnerata@savagejen In all seriousness I wrote a long and pretty dumb blog post on this question. http://blog.cryptographyengineering.com/2012/07/four-theories-on-cryptography-of-star.html … -
@matthew_d_green@puellavulnerata@savagejen ever seen this? search for "cipher": http://www.st-minutiae.com/academy/literature329/207.txt … -
@bascule@matthew_d_green@savagejen The dialogue seems to more or less support my "Trek crypto is reduced to the Vigenere level" theory. -
@puellavulnerata@matthew_d_green@savagejen if you read past the Treknobabble it sounds like they're using a 43-part product cipher -
@bascule@puellavulnerata@savagejen Their encryption is obviously based on RC4. -
@matthew_d_green@puellavulnerata@savagejen RC4 and 41 other ciphers that Data knows how to break! Just can't get #29 for some reason

@bascule@matthew_d_green@savagejen Seems pretty hard to transpose any of our complexity theory to a world where it's a dynamical variable. -
@puellavulnerata@matthew_d_green@savagejen A Fire Upon the Deep used a sneakernet of spaceships with fragments of secret shared OTP pads -
@bascule@matthew_d_green@savagejen Crap, I'd forgotten that detail. Need to re-read it... -
@puellavulnerata@matthew_d_green@savagejen yeah, it was basically the endgame for cryptography: OTP was the only thing that worked -
@bascule@puellavulnerata@savagejen Greg Egan used quantum key distribution. Same deal.
