  • @ibell63 Perhaps you should consider migrating to the McEliece public key encryption system instead. It is free of all of the problems of RSA being cracked with quantum computers and all of the problems presented by quantum encryption.

    McEliece sound like a good solution to me.

  • @ibell63 Nothing. That's the problem with quantum encryption unless you can verify that the photons came from the source you think they came from you are susceptible to a man-in-the-middle attack.

    There is a "GPS" protocol for quantum encryption that uses 3 strings of photons and precise timing to assure the location of the sender and receiver that attempts to solve this problem. The problem with this is that it only works over very short distances.

  • can't find a full explanation anywhere.... so frustrating

  • Does the light source have any control over what key it produces or is it random?

  • What stops someone from placing telescopes in between alice and bob and the photon source and capturing and then replaying the key?

  • ohhhhhhhh
