Remember the infamous snowden affair, when there was a general question about why the United States was able to monitor and monitor the world?The reason is that America's information network is incredibly powerful, and the world is highly dependent on America's information network technology, which is the key technology.No matter how sophisticated the device is, its data is stored on a small chip.But the chip with infinite power has a fatal weakness, that is its "destiny" is in the hand of the designer, the industry commonly known as "back door".If you don't have a key core technology, the "back door" that the designer left behind will expose all your secrets to people in an instant.

In fact, the us government's control of core chip technology has never stopped before it was banned.On April 9, 2014, the us Commerce Department announced that decided to reject Intel sold to national supercomputing center in guangzhou China "to" (XEON) chip is used for "tianhe ii application system upgrade.At the time, the U.S. department of commerce argued that the "tianhe-2" system, which used two Intel microprocessors, and the earlier "tianhe-1" A system, "are believed to be used for nuclear detonation simulations."This reason is difficult to convince, because all the expert inside course of study thinks, whether it's for security or confidentiality point of view, "tianhe ii can't directly used in a nuclear blast simulation.
