SK Telecom and Nokia have developed a prototype quantum cryptography system that combines the South Korean company's quantum key server with an encryption device from Nokia.
The system, shown Monday at Mobile World Congress in Barcelona, was put together to demonstrate interoperability between the two vendors and comes as SK Telecom kicks off a push to get telecom carriers and equipment vendors working together on next-generation quantum-secured networks.
Quantum cryptography involves the transmission of encryption keys across fiber optic networks. It relies on the principles of quantum mechanics to detect if an eavesdropper has viewed a key en route.
