"However, a few nations are now proposing surreptitious and covert methods for obtaining private keys and access to encoded communications".
Mr. Mohammed, who had attended college in North Carolina, taught the men English phrases, showed them how to read a telephone book, make flight reservations, use the Internet and encode communications.
Afterward, K.S.M. taught three of these operatives basic English words and phrases and showed them how to read a phone book, make travel reservations, use the Internet and encode communications.
The Adaptive Wireless Engine, as it is called, is a device whose logic cells have been specifically designed to handle signal filtering, speech encoding, wireless communications protocols, and so on in other words, the sorts of things that mobile phones have to do.
The NSA was intended to be the world's premier SIGINT agency, encoding American secret communications while stealing and decoding other nations'.
Interpretive communications encode messages that require intellectual effort by the receiver to understand the sender's meanings.
From very early in the war the Government Code and Cypher School (GC&CS) was successfully deciphering German radio communications encoded by means of the Enigma system, and by early 1942 about 39,000 intercepted messages were being decoded each month, thanks to electromechanical machines known as 'bombes'bombes
Results: Researchers at the University of Toronto have dramatically increased the distance that a quantum key – photons that represent bits of data for encoding and decoding secret communications – can travel by modifying a commercial quantum encryption system.
The system which encoded and decoded voice communications, was intended to be used in a similar way to a telephone scrambler.
This pioneering effort is an early attempt to transmit data from a satellite using optical communications—sending information encoded in light rather than radio frequencies.
