Scientific American on Quantum Encryption

Posted by samzenpus on from the just-try-and-break-it dept.

prostoalex writes "Scientific American claims that advances in commercially available quantum encryption might obsolete the existing factorization-based solutions: "The National Security Agency or one of the Federal Reserve banks can now buy a quantum-cryptographic system from two small companies - and more products are on the way. This new method of encryption represents the first major commercial implementation for what has become known as quantum information science, which blends quantum mechanics and information theory. The ultimate technology to emerge from the field may be a quantum computer so powerful that the only way to protect against its prodigious code-breaking capability may be to deploy quantum-cryptographic techniques.""

    Someone needs to write a Encryption routine that uses the source text as the key. THAT will really show 'em!

      Already done - XORing the source text with itself is a provably perfectly secure form of encryption!

      But you still need to apply for an export licence if you use a encryption key greater than 128 bits in size.

  2. n.b does not hurt cats unless you observe them by Engineer+Andy · · Score: 5, Funny

    As far as I can tell, no cats were harmed in the making of these quantum cryptographic devices, although if you look inside the box, the act of looking at the cat inside may (or may not) kill it

    Quantum computing doesn't make threats.

    It makes promises.

    so you gonna break his face and slam a cardboard box over his head? "no officer, his face is not smashed. however, if you take the box off it might cause it to be smashed or not"
