Securing Fiber Using Light Polarization
screenbert writes: "A new and novel way of
communicating over fiber optics is being developed by physicists supported by
the Office of Naval Research. Rather than
using the
amplitude and
frequency
of
electromagnetic waves, they're using the polarization of the wave to carry
the signal. Such a method offers a novel and elegant method of secure
communication over fiber optic lines. This
press release has more information. Of course I always thought that fiber
was always pretty secure anyway since it's a lot harder to tap than copper."
"It provides a definite advantage over direct encoding of polarization, leaving an eavesdropper only chaotic static, and no means to extract the signal."
Why the extra security? There's already the depths of the ocean, the difficulty of trying to tap a fiber line, not to mention whatever encryptation they have on their data. They must be looking at some questionable pr0n to go to these lengths.
Job? I don't have time to get a job! Who will sit around and bitch about being broke and unemployed then?
Because it was harder to tap than string between cans.
Is this the promised end? Or image of that horror? KING LEAR
Because it was harder to tap than two guys yelling across the yard at each other.
Why go through the trouble of intercepting it at the fibre level when we can just intercept it near their WiFi stations?
Then they should rename USS Jimmy Carter to USS Richard Nixon or maybe USS Deep Throat :-)
