SK Telecom announced on Feb. 7 that its two techniques related to quantum cryptography communications have been adopted for international standardization projects at a recent ITU-T conference in Geneva, Switzerland. Techniques adopted for such projects become global standards after discussion with dozens of countries in the ITU-T.
The two techniques are related to a system for quantum key distribution in a communications network and a method for using an existing encryption scheme for quantum key distribution. Both techniques are essential for quantum cryptography application to communications networks.
Earlier, in September 2018, SK Telecom presented and obtained an approval for details to be reflected in the final standards of a security framework for quantum key distribution in a communications network and a security technique for quantum random number generators, which were adopted for the ITU-T’s international standardization projects.
As a result of the additional adoption, SK Telecom has become a company in charge of four ITU-T international standardization projects in the field of quantum cryptography. At present, SK Telecom is the only company in the world that is in charge of at least four such projects in that field.
