| Quantum cryptography scrambles data in a different way to conventional cryptography, because the information about security keys is encoded on to a single photon of light. "Quantum cryptography is already in use," said Dr Lam. "Its popularity at the moment is very modest. However, I believe this will change in the next few years. "We can prove that, if done right, it is absolutely secure against eavesdroppers. A 'disembodied' transmission of information is therefore a good starting point for crypto-communication." |
