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%

SK Telecom to launch 802.11.ax Wi-Fi

SK Telecom is preparing to launch a next-gen public Wi-Fi service based on the 802.11.ax, which offers up to 4.8 Gbps per AP. This is about four times faster than the Giga Wi-Fi (802.11ac Wave1, 1.3Gbps) that SK Telecom first commercialized in 2013.

'T Wi-Fi AX' uses four antennas to transmit and receive radio waves, and the available frequency bandwidth is 160MHz, which is twice the conventional Wi-Fi. The 2.4GHz and 5GHz frequency bands are used.

The latest Samsung Galaxy smartphones are equipped with 802.11.ax chips, and SK Telecom anticipates that other models will be as well.

"T Wi-Fi AX" is the first in Korea to utilize commercial APs that have been officially certified by the government. The AP received an electromagnetic compatibility certification from the National Institute of Advanced Industrial Science and Technology (AIST) at the end of August and final equipment approval from the Ministry of Information and Communication.

SK Telecom picks Samsung, Ericsson and Nokia for 5G

SK Telecom – setting the pace in the 5G race



SK Telecom, South Korea's leading mobile operator by market share, is one of the big players to watch on the global stage for early 5G commercialisation. In fact, a race is on with local rivals KT and LG Uplus to have the first 5G service running in time for the 2018 Winter Olympics, which will be hosted in Pyeongchang, South Korea in February 2018 - only seven months away. Of course, 5G standards are not complete and won't be in time for the Winter...

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.

SK Telecom – setting the pace in the 5G race

SK Telecom, South Korea's leading mobile operator by market share, is one of the big players to watch on the global stage for early 5G commercialisation. In fact, a race is on with local rivals KT and LG Uplus to have the first 5G service running in time for the 2018 Winter Olympics, which will be hosted in Pyeongchang, South Korea in February 2018 - only seven months away. Of course, 5G standards are not complete and won't be in time for the Winter Olympics, which means that network planners will be rushing to show off systems that have barely been tested. Sceptics will say that 5G demos at Pyeongchang are likely to be very limited in their footprint and perhaps only 4.5G rather than truly next gen. However, SK Telecom has a track record of being first with many networking technologies, extending back to its earliest days in CDMA.

Background

South Korea's mobile market is one of the most mature in the world. There are three dominant mobile operators: SK Telecom (approximately 49% share), KT and LG Uplus. Mobile penetration has exceeded 110% for years. The majority of users are on subscription-based plans, rather than prepaid, and churn is relatively light compared to other countries.

SK Telecom, part of the SK Group conglomerate (chaebol), was founded in 1984 and has a CDMA network architecture heritage. For its most recently reported fiscal quarter, SK Telecom posted revenue of KRW 4.234 trillion, operating income of KRW 410.5 billion, basically flat from a year earlier, and net income of KRW 583.5 billion, up 2.1 %YoY. As of the end of March 2017, SK Telecom had 21.65 million LTE subscribers, representing a 10.9% YoY growth, and taking up 72.6% of the company's total mobile subscriber base of 29.83 million. ARPU was KRW 34,927 ($31.04), down 2.9% YoY. SK Telecom also operates the Cyworld social network and virtual reality service as well as the Nate-on messaging application.

First in Carrier Aggregation

This week, SK Telecom announced the launch of LTE-A Pro service, which it described as the last stage of LTE evolution. The service footprint covers the main areas of six major cities: Seoul, Busan, Daegu, Gwangju, Daejeon and Ulsan. The initial LTE-A Pro service uses three-band/four-band carrier aggregation (CA) to deliver rates of up to 700 Mbit/s. When 4 x 4 MIMO is added, the service accelerates to 900 Mbit/s. SK Telecom plans to scale up LTE-A Pro further using five-band CA with 4 x 4 MIMO to achieve 1.2 Gbit/s peak rates. The first mobile device to support the LTE-A Pro service is Samsung’s Galaxy S8. An over-the-air firmware update will be needed to support the additional CA bands.

SK Telecom's spectrum resources include 10 MHz bandwidth in the 800 MHz band, 20 MHz bandwidth in the 1.8 GHz band, 10 MHz bandwidth in the 2.1 GHz band, 10 MHz + 20 MHz bandwidths in the 2.6 Ghz band.

Peak speeds of 700 Mbit/s and up on a mobile phone are certainly impressive. Actually, SK Telecom has been delivering a 500 Mbit/s mobile service since June 2016 using 256QAM combined with tri-band CA. Four years ago, in June 2013, SK Telecom launched the  first LTE-A service, which boasted download speeds of up to 150 Mbit/s, which is two times faster than its regular LTE service and 10 times faster than its 3G network. This was achieved using CA across two 10 MHz channels, along with the first Coordinated Multi Point (CoMP) implementation. Samsung's Galaxy S4 handset, which was the latest and greatest model in the summer of 2013, was the starring device for this milestone service launch as well.

Many world capitals today have yet to attain the 150 Mbit/s performance peaks offered in Seoul four years ago. But surprisingly, SK Telecom's LTE adoption rate amongst is 29.8 million mobile subscribers was only 72%, or 21.6 million users, as of March 2017. This means that even for a mobile operator with the most advanced network in the world, a significant percentage of users are laggards when it comes to updating to the latest service.

Recently, SK Telecom gained recognition for two other technology innovations: 5G mmWave Handover and a Green Scheduler with Lean Carrier algorithm. Both advances won Global Telecoms Business (GTB) Innovation Awards last month. The 5G mmWave handover technology, developed with Samsung, supports Gbit/s-level performance using multiple mmWave 5G base stations. The companies used the Ray Tracing method to calculate the optimal location of mmWave base stations. SK Telecom and Samsung also cited their work in 3D beamforming to resolve attenuation of radio signals in mmWave frequencies. The Green Scheduler with Lean Carrier technology, which was developed in partnership with Ericsson, enhances network energy efficiency while reducing signal interference.

With Ericsson, SK Telecom is also known to be working on a 5G connected car program. Earlier this year, SK Telecom, Ericsson and BMW Korea achieved a peak rate of 3.6 Gbit/s for a connected vehicle travelling at a speed of 170 km per hour. To pull this off, the three companies deployed the world largest mmWave 5G trial network using the 28 GHz band. Beamforming and beam tracking technologies were used to optimise the connection to the speeding car.

Leaping ahead in quantum technologies

To further illustrate its interest in pushing technological boundaries, SK Telecom signed separate research partnerships earlier this year with Nokia and Deutsche Telecom focused on quantum cryptography. The first partnership will match SK Telecom's Quantum Key Distribution System (QKD) with Nokia’s next-generation optical transport system. The first prototype was shown at Mobile World Congress in February.

Nokia and SK Telecom are also collaborating on a Quantum Random Number Generator (QRNG), which is seen a key technology for applying quantum cryptography technologies to IoT devices. SK Telecom has developed what it claims to be the world’s smallest 5 x 5 mm CMOS Image Sensor (CIS) based all-in-one, single silicon (ASIC) for providing non-deterministic true random numbers on demand from quantum-shot noise. The plan is to commercialise the technology to enable secure IoT.

SK Telecom's Quantum Alliance with Deutsche Telekom is more open. At this stage, the agreement aims to the channels of communications open between carriers and vendors when it comes to quantum technologies. The official statement from the company, by, Cha In-hyok, EVP and head of IoT business division, states:

    “Committed to building a quantum-safe future, SK Telecom has been actively developing quantum cryptography technologies since 2011. SK Telecom believes that the co-establishment of the Quantum Alliance with Deutsche Telekom will bring us closer to realizing this goal, while also creating new valuable business opportunities in areas including quantum-safe communications, the Internet of Things and big data. It will work together to accelerate the growth of quantum-based cybersecurity technologies and its ecosystem".

SK Telecom and Deutsche Telekom Launch Quantum Alliance for Secure Communications

SK Telecom of Korea and Deutsche Telekom announced at MWC 2017 that they have established the Quantum Alliance, designed to enable secure communication in the quantum computing era.

The companies noted that with industrial espionage and cyber-attacks a growing threat, plus the prospect in the near future that quantum computing could enable the cracking of existing encryption algorithms, today's common cryptography methods could become ineffective, meaning that server access, data links and documents, and the Internet as a whole, could be insecure and easily accessible.

In an effort to address this, SK Telecom and Deutsche Telekom have founded the Quantum Alliance, intended to ensure communications remain secure and with the primary objective of establishing the technical prerequisites for secure communications into the future. The partners believe that to achieve this network operators and hardware manufacturers will need to work together to define and implement common, global technical standards.

As a second step, the Quantum Alliance will seek to develop flexible services and security solutions that maintain secure communications. In the medium-term, the alliance has a target of developing, testing and delivering products that enable secure communications in the age of quantum computing.


As part of the initiative, SK Telecom and Deutsche Telekom are committed to recruiting partners for the alliance over the coming months, and plan to approach network operators, network equipment makers, device manufacturers and software vendors. Working with the new partners, the companies then plan to create a detailed action plan for how to proceed.

Recently, SK Telecom and Deutsche Telekom (DT), working with Ericsson, announced a joint demonstration of an intercontinental 5G trial network providing network slices in each operator's footprint covering South Korea and Germany. The demonstration was hosted at DT's corporate R&D centre in Bonn, Germany and the SK Telecom 5G Testbed at Yeongjong-do (BMW driving centre) in Korea, and followed the announcement of a collaboration on 5G at MWC Shanghai 2016.

The partners noted at the time that at MWC 2017 they would demonstrate the creation and management of federated network slices in a NS-as-a-Service (Network Slice as a Service) model.
