Newswise is reporting that the [a href="vny!://www.newswise.com/articles/view/521790/?sc=rsla"]encryption in the Galileo GPS signal has been broken[/a]. The pseudo random number generator used to obscure the information stored in the Galileo GPS signal has been successfully decrypted and is now available for mere mortals (like you and I) to use. Ha ha!
From the article: 'Members of Cornell's Global Positioning System (GPS) Laboratory have cracked the so-called pseudo random number (PRN) codes of Europe's first global navigation satellite, despite efforts to keep the codes secret. That means free access for consumers who use navigation devices -- including handheld receivers and systems installed in vehicles -- that need PRNs to listen to satellites.'
The Cornell team anaylzed signals from a demonstration satellite that by itself is not useful for navigation, and according to the documentation transmits the same power-envelope, but not the same PRN's, as the operational system. According to Cornell's lawyers, the [a href="vny!://en.wikipedia.org/wiki/DMCA"]DMCA[/a] was not a concern because navigation data is not, and cannot be, copyrighted.
