By using a novel method (covered by trade secret law and now patent-pending in 26 countries) our server software transmits packets onto your local network without reading them, thus preserving their unique quantum properties. Any attempt to read the packet, except by the intended recipient will destroy the quantum waveform of the packet. Our sophisticated error-recovery system will detect this and re-initialize with a predefined Emergency Quantum State, which has all the same characteristics as the Normal Quantum State, but has not been compromised by the attempted eavesdropper.

Unfortunately, the method can be cracked easily. Because the system uses two patented states, a Normal Quantum State and an Emergency Quantum State, and it's patent-pending in 26 different countries, you can divide the 26 patent-pending states by the two patented states giving a pending 13. By rotating the 13 twice, of course, the original text can be recovered. However, the method is partially useful, using a lemma by Dr. Denning. While 26 is divisible by 2, it's not divisible by 3, so the addition of a third state renders it effective again. Denning's paper recommends use of a National Security State as the additional state, which provides effective protection, additional security and supports the legitimate needs of law enforcement. So if you want your crypto to be secure, it's an offer you can't refuse... Another approach has been suggested by the Syndicate for Quantum Deconstruction, in their prescient 1998 paper "Smash the State". By deconstructing the quantum packet on arrival, an imbalance is created which can only be resolved by constructing the packet an equal time period before the origination of the packet in the Normal Quantum State. In addition to preventing the emergence of the Emergency Quantum State, it allows, and in fact requires, the packet to be present and read some time before its original transmission time. Copies of the paper are currently circulating only as preprints; the original will be posted on http://www.timenet.net/1998/Physics/~SQuD/Deconstruct.vrml as soon as it becomes available. #-- # Thanks; Bill # Bill Stewart, stewarts@ix.netcom.com, +1-415-442-2215 pager 408-787-1281 1995: Chat rooms, espresso, and Linux 1996: Exon, melatonin, and Java.
