SK Telecom applies Quantum Cryptography to network security

SK Telecom has applied a Quantum Random Number Generator (QRNG) developed by ID Quantique of Switzerland to its 5G authentication center (AuC). QRNG is a device that constantly generates “quantum random numbers,” which creates strong keys that are not biased and cannot be predicted. SK Telecom said it plans to apply the same quantum random number technique to its 4G network as well.

Next month, SK Telecom will also apply ID Quantique’s Quantum Key Distribution (QKD) technology to the Seoul-Daejeon section – the most data traffic-concentrated section in Korea - of its 5G and LTE networks, to strengthen the security of 5G and LTE data transmission and reception. QKD provides ultimate cryptographic security based on the laws of quantum mechanics. It enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages.

SK Telecom invested US$65 million in ID Quantique in February 2018.

SK Telecom also noted its pivotal role in global standardization of QKD and QRNG technologies at ITU-T. In February 2019, SK Telecom’s two new technologies related to QKD have been selected as work items by ITU-T’s Study Group 17 (SG17), which coordinates security-related work across all ITU-T Study Groups. Combining these two work items with the two on-going work items on QKD and QRNG technologies it proposed in July 2018, SK Telecom is currently leading a total of four meaningful work items in SG 17. In addition, Sim Dong-hi, a delegate from SK Telecom,  is serving as associate-rapporteur on quantum technology in SG17.

“As security emerges as one of the most important issues in the 5G era, SK Telecom is determined to provide the most secure 5G network and focus on expanding the ecosystem by developing quantum cryptography technologies,” said Park Jin-hyo, the Chief Technology Officer of SK Telecom.

SK Telecom's Mobile Edge Computing box cuts 5G latency a further 60%

Korea's SK Telecom achieves 1 Gbit/s with Ericsson LAA

Ericsson announced that SK Telecom, a major mobile operator in South Korea, has tested mobile broadband using Ericsson's Licensed Assisted Access solution, during which it achieved data speeds of up to 1 Gbit/s to smartphones in an indoor environment.

Ericsson noted that Licensed Assisted Access (LAA) technology utilises licensed LTE spectrum and unlicensed spectrum, and in the testing SK Telecom used one LTE 20 MHz band and three WiFi 20 MHz bands, also applying Ericsson's 4 x 4 MIMO functionality in the LTE frequency band. Additionally, Listen-Before-Talk technology was applied to both the WiFi and LTE networks to optimise the utilisation of available spectrum and reduce resource contention.
Using Ericsson's LAA solution, broadband users are able to connect via WiFi automatically to leverage the benefits of LTE. This enables users to access the network more quickly and, when terminating a session, network resources are released more quickly. This helps improve the utilisation of the unlicensed spectrum and service quality.


* Recently, SK Telecom announced that in collaboration with Samsung Electronics and Nokia it had demonstrated 5G communications using the 3.5 GHz band for the first time in Korea. SK Telecom teamed with Samsung Electronics to develop a 3.5 GHz 5G end-to-end network with 5G virtualised core, virtualised RAN, distributed unit (baseband and radio unit) and test device based on 3GPP 5G New Radio (NR) standards elements.

* SK Telecom also worked with Nokia to co-develop 5G base station equipment and test device for the 3.5 GHz spectrum and achieved Gbit/s-level throughput during a field trial held near its Bundang office building through the application of carrier aggregation to increase bandwidth. The two companies also measured link quality (BLER) depending on the distance between a moving vehicle and base station.

* SK Telecom stated that with the successful trials of 3.5 GHz 5G networks, it has secured the essential technologies to deploy 5G networks using above-6 GHz and below-6 GHz frequencies. The company expects that 28 GHz, a potential above-6 GHz frequency in Korea, will support tens of Gbit/s through the use of a wide bandwidth of hundreds of MHz, while the 3.5 GHz band can be used to provide wide area coverage.

SK Telecom commercialises T-MANO NFV

Korea's SK Telecom announced that it has commercialised T-MANO, an NFV MANO (network functions virtualisation management and orchestration) platform that performs integrated management and orchestration of virtualised network equipment and software.

SK Telecom noted that NFV MANO, also termed MANO, provides an architectural framework for managing and orchestrating virtualised network functions (VNFs) and other software components. The new T-MANO solution has been optimised to SK Telecom's network environment, and is based on the ETSI specifications that define the MANO architecture to facilitate the deployment and connection of services as they are decoupled from dedicated physical devices and moved on to virtual machines (VMs).

Prior to the development of T-MANO, SK Telecom stated that it was necessary to develop, build and operate a separate NFV management platform for each network equipment provider due to the fact that each piece of NFV equipment was based on different specifications, depending on the manufacturer.

Leveraging T-MANO, SK Telecom is able to more efficiently utilise its virtualised network equipment by managing service quality and data traffic in an integrated manner, regardless of equipment manufacturer, while improving the overall service quality through responding flexibly to service failures and errors.

The solution also enables the company to significantly reduce the time required to set up new equipment and provide a new service as it can upgrade the whole system at once, as opposed to upgrading each system separately as was necessary previously.

SK Telecom intends to leverage T-MANO to expand the telecommunications infrastructure ecosystem by opening up the APIs of T-MANO so that the industry can use it to build virtualised network equipment or software.

The company will first apply T-MANO to its virtualised VoLTE (HD Voice) routers, and then plans to expand its application to the virtualised LTE evolved packet core (EPC) and additional equipment including MMS Servers. SK Telecom stated that in 2017, virtualised EPC will account for around 80% of newly-deployed EPC equipment, while from 2019 it intends to deploy only virtualised EPC solutions.

In the field of NFV, SK Telecom has also commercialised an international standards-based NFV system orchestrator, named T OVEN, that was unveiled in 2015, and applied NFV technology to its base station equipment in September 2016.
