An international team of scientists claims it has achieved perfect secrecy cryptography, one that cannot even be decoded by quantum computing. The team has developed a prototype silicon chip that uses the laws of nature, including chaos theory. With no software or code to manipulate, traditional methods of cracking computer encryption are irrelevant, the scientists claim.
This technology probably will not be available in consumer devices for a few years yet, but undoubtedly will be available as prices drop. You can read more in an article by Davey Winder in Forbes at http://bit.ly/2SvwyVB.
