UK Researchers Achieve Secure Key Transmission Over 14.5 Miles

UK researchers have managed to send untamperable encryption keys over long distances, opening the way for totally secure communications. A team of scientists said on Wednesday they had made a major leap toward developing secure global communications.

Researchers from QinetiQ, the commercial arm of Britain's defence research agency, and their colleagues at Ludwig-Maximilian University in Munich have sent a key for deciphering coded information over a record 14.5 miles of open space between two mountains in Germany.

"This is the only way to distribute keys for encoding data in absolute security without actually sending a guy with a briefcase," John G. Rarity, of QinetiQ, told Reuters.
