LG Uplus is set to create international standards for service quality management in communication environments utilizing next-generation security technologies such as Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD). The aim is to systematically manage the increased latency during the encryption process while maintaining the quality level of existing communication services.
On July 12, LG Uplus announced that it recently proposed the development direction of next-generation security communication quality management technology, co-developed with IoT Communication Tech, at the International Telecommunication Union's Telecommunication Standardization Sector (ITU-T) SG13 meeting held in Geneva, Switzerland.
The ITU-T is an international organization that establishes global communication technology standards, and SG13 is a group that researches future networks and service quality. This technology was adopted as an ITU-T international standardization project in February and will be developed into an international standard after consultations among member countries and companies.
PQC is a mathematics-based encryption technology that is difficult to decrypt even under attacks from quantum computers, while QKD is a technology that securely transmits encryption keys using principles of quantum mechanics. Both technologies are considered essential for implementing next-generation secure communications. However, applying them to communication networks may increase latency due to the additional processes of encryption, decryption, key generation, distribution, and management. This has been identified as a challenge for the telecommunications industry, which aims to enhance security while maintaining the quality of existing communication services.
In light of this, LG Uplus proposed latency-related quality management standards that can maintain the quality level of existing services even in encrypted communication environments. For latency-sensitive services like voice calls, the target standard is set at approximately 0.15 seconds (150 ms), a level at which users do not experience discomfort.
They also presented a plan to manage transmission delays in the communication network alongside delays arising from encryption processing. This comprehensive management of various delay factors during communication aims to maintain the perceived call quality and service stability for customers while applying next-generation security technologies.
If this technology is confirmed as an international standard, global telecommunications operators, equipment manufacturers, and security companies will use it as a basis for applying next-generation security technologies to communication networks and managing encryption service quality. LG Uplus plans to accelerate the establishment of next-generation secure communication environments through the development of international standards.
Kim Jong-cheol, head of wired technology at LG Uplus, stated, 'In the next-generation secure communication environment, not only security but also the quality perceived by customers is important,' adding, 'We will strengthen our technological competitiveness in the global telecommunications market through the development of international standards.'
