EVANSTON, Ill. -- Put aside images of World War II espionage and codebreaking. Today cryptography is vital to the security of a form of communication and commerce never imagined 60 years ago: the Internet. Researchers at Northwestern University now have demonstrated a new high-speed quantum cryptography method that uses the properties of light to encrypt information into a form of code that can only be cracked by violating the physical laws of nature.
The above story is based on materials provided by Northwestern University. Note: Materials may be edited for content and length.
