CCC: Eavesdropper for a quantum cryptosystem

[ElZorro]

Presentation at CCC. Even before quantum crypto is in your hands (and maybe before you even knew it was real and not just sci-fi) its already being hacked.

This presentation will show the first experimental implementation of an eavesdropper for quantum cryptosystem. Although quantum cryptography has been proven unconditionally secure, by exploiting physical imperfections (detector vulnerability) we have successfully built an intercept-resend attack and demonstrated eavesdropping under realistic conditions on an installed quantum key distribution line. The actual eavesdropping hardware we have built will be shown during the conference.

Very impressive indeed!

that's super rad.
