Light as a perfect encryption

So far, the mathematical encryption to withstand even the most hack attacks. But computers get faster and faster. “It’s only a matter of time before unauthorized persons to hack into the most protected computer,” says Horace Yuen, Project and professor of electrical engineering and computer sciences at Northwestern University.

But Yuen has a solution with quantum encryption at hand. While current encryptions are based on mathematical relationships, the new method uses light to manipulate the data. The resulting patterns are much more complex pattern than just “on” or “out” as with traditional methods. The content or attachment in an encrypted mail using the new method had become unreadable, because the data is too much “junk data” contained.

His invention is particularly timely in light of global terrorist attacks. A threat against one of’m afraid, is to control the entry into systems which use water or electricity. “These same machines need better security,” said Yuen.
