Einstein key stops hacks 10/05
The Australian, November 08, 2005 - - 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 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.
They uncovered a phenomenon known as entanglement, a theory that described the way particles of energy interacted predictably with each other.
Applying this theory in the field of quantum cryptography allowed the ANU group to generate a secret key that prevented data from being hacked. The discovery was expected to be of particular interest to defence and intelligence organisations, governments and the finance sector because it allowed communication without eavesdropping.
