O2 has announced that it is deploying new data security between its key data centers against quantum computers. The data centers are operated by CETIN, the largest telecommunications infrastructure provider in the Czech Republic. O2 and CETIN confirm their technological lead and readiness for new security challenges associated with the development of quantum technologies. O2 is the first in the Czech Republic to deploy quantum-resistant network security. The new technology protects the backbone network for mobile and data services from future threats.
The new highest security layer protects the network connection between two main data centers in Prague, operated for the operator by CETIN. These centers are the fundamental pillars of the entire O2 network and ensure the operation of core mobile and data service systems, including LTE, 5G, VoLTE and IoT networks.
CETIN has deployed quantum key distribution technology for the O2 network , connecting two main data centers in Prague with an optical link secured by these keys. This step will contribute to even greater security of data stored in the data centers. CETIN also plans to gradually add quantum key distribution equipment to other secure network nodes. The optical link connecting the data centers is 25 kilometers long, but the technology used allows for secure data transmissions up to a distance of 120 kilometers.
CETIN has invested millions of crowns in equipping data centers with quantum key distribution equipment. The security uses the QKD method, i.e. Quantum Key Distribution. CETIN is working on this method with its partner ID Quantique, a Swiss company that was founded in 1990 as a spin-off from the University of Geneva and offers a number of solutions for quantum key transmission and quantum attack detection.

O2 is the first in the Czech Republic to deploy quantum-resistant network security. The new technology protects the backbone network for mobile and data services from future threats. We are responding to the growing risks associated with the development of quantum computers.
Radek Šichtanc, Director, Security, O2
Cryptography is a fundamental building block of security in the digital world, whether it concerns secure communication on the Internet, electronic signatures, identity verification, secure data storage and many other applications. I see the deployment of new technologies such as quantum key distribution and post-quantum cryptography, resistant to future threats using quantum computers, as a fundamental step by O2 to ensure long-term protection of information.
