Re how did nobody else find out about this until now?
The same reason NATO and other US allies did not understand the NSA Martin and Mitchell defection http://en.wikipedia.org/wiki/M...
in 1960 with the press conference saying:
"As we know from our previous experience working at N.S.A., the United States successfully reads the secure communications of more than forty nations, including its own allies."
Embassies, govs and firms went on using the same junk standard crypto hardware over decades of revisions. Some even got to re read their own secure embassy communications 'leaked' to the Western press.
There seems to be something missing on the story of gov, staff and developers when it comes to crypto products.
Skilled EU gov experts handing their own political leaders broken crypto that 5++ other nations can break seems too good to be true over generations.
Junk in the hardware decades, junk in the software decades all for speed, interoperability and after a good sales pitch?
Or a lot of skilled people around the world know and just tell their respective govs to bait the junk communications networks until US political leaders speak out.
