Introduction to EncryptionThere is no one single way to encrypt a file. Hundreds of ciphers exist today and many more are being developed every year. Some can be done with nothing more than a pencil and a piece of paper, while others require the number-crunching power of a computer to be effective and practical. In this article, Joshua Ryder presents some basic examples to illustrate how encryption works.

The Ghost of Fireballs PastEerie-sounding echoes from Leonid and Geminid meteors were captured by amateurs monitoring the Navy's Space Surveillance Radar. During a shower like the Leonids, radio signals from TV stations, RADAR facilities, and AM/FM transmitters are constantly bouncing off meteor trails. The echoes can be heard around the world.
Naval Space Surveillance System : NAVSPASURNAVSPASUR is a unique multistatic radar system that detects orbital objects passing over the contiguous United States. It can detect objects as small as 10cm diameter at orbital heights up to 15,000 nautical miles, and measure the positions and velocity vectors of detected objects as they pass through its detection plane. It is operated by the US Navy, has headquarters at Dahlgren, Virginia, and is an important data source for NORAD .
At Lourdes, air is filled with secrets
Just south of the Cuban capital’s Jose Marti airport—and clearly visible to passengers on final approach—is a little known Russian military base, one without weapons systems but with scores of antennas and satellite dishes straining to hear some of America’s closest held secrets.

DSD - Sigint and history
Signals intelligence and information security have a long and honourable history in the service of the Australian Government and its allies in times of peace, crisis and conflict. The current generation of Australia's Sigint and Infosec professionals are proud to inherit that record, and to add their own contributions to it.
But it is a history little known to the public at large. Because of the secrecy that surrounds the the business of intelligence collection, many of the great successes of Sigint cannot be revealed until many years later.
