Hacking: New laser may stop computer hackers
A THEORY first proposed by Albert Einstein 70 years ago has provided the basis for a new electronic "key" that could spell the demise of computer hackers.
Physicists at the Australian National University (ANU) have successfully used bright lasers to prevent transmitted data from being hacked.
Their breakthrough was based on work done by Einstein and his colleagues in 1935 who uncovered a phenomenon known as entanglement, a theory which described the way particles of energy interacted predictably with each other.
Applying this theory in the field of quantum cryptography had allowed the ANU group to generate a secret key that prevented data from being hacked. The Australian: New laser may stop computer hackers [November 07, 2005]
