Super-secure network could flag data danger
It's a hacker's nightmare but a dream for bankers and spies: A computer network so secure that even the simplest attempts to eavesdrop will interrupt the flow of data and alert administrators to the snooping.
The work by researchers at Harvard University, Boston University and BBN Technologies is the closest scientists have come to a real-world quantum encryption system that uses light particles called photons to lock and unlock information instead of random-number "keys."
Using the technology, the scientists can swap data, send e-mail and visit one another's Web sites as their data is protected.
