Three telecommunications companies, preoccupying in the field of quantum cancers,

The era of quantum computers that go beyond the performance of supercomputers came to the front. The telecommunications industry is also accelerating technology development in order to develop competitiveness in the quantum cancer telecommunications market.

According to the industry on the 14th, SK Telecom and KT have a quantum cancer hooki distribution (QKD) application method, while LG Uplus is developing technology using quantum resistance (PQC) to future the Internet of Things (IoT), Finance, City Airlines. The plan is to use it for security in various areas such as the mobility (UAM) field.

QKD is a method of increasing security by creating a cryptocurrent key that can only decipher the transmitter and receiving parts. Since the process of sending and receiving information to create a secret key is proceeded in the quantum state, the third party does not know any information about the encryption key.

PQC is a method of creating and using a password that is difficult to solve using mathematical algorithms. In particular, PQC is based on grid passage. The grid is a way of keeping my password for the problem of dots between grids and finding the closest grid.

SK Telecom is developing a quantum cancer chip 'Q-KEV7', which combines KCS's quantum creation (QRNG) and cryptocurrency semiconductors, with the goal of December this year. SK Telecom aims to obtain Q-KEV7 certification of KCMVP from the national information provider by the first half of next year.

SK Telecom plans to enter the defense weapon system project such as drones, public institutions such as KEPCO, and Wallpad, and Wallpad. An official of SK Telecom said, We believe that security will be strongly required in the defense sector, he said.

KT is immersed in standardization research. There are 31 quantum cryptography networks related to the standardization of ITU-T, which is the standardization of ITU (ITU), or is conducting research evaluation. About 35% of them were led by KT. KT is developing standards for quantum cryptography networks, the largest number of ITU member companies.

KT launched quantum cancer communication quality evaluation in 490km from Seoul to Busan in March, and will launch a dedicated line for quantum cancers within the year and proceeds with the concept of a quantum cryptography relay.

LG Uplus launched a PQC-only line in April. It is a dedicated line that provides a security environment that is impossible to hack through the ROADM with PQC technology. It adds security by using PQC to a safe dedicated line, and protects the information by cancer and decrypting data with a PQC key when sending and receiving data through a dedicated line.

LG Uplus plans to strengthen security by applying PQC exclusive lines to the joint 5G network. In the future, we plan to expand our business to various fields such as UAM. It is also creating certification guidelines for KCMVP certification. When the certification is completed, the reliability of PQC is expected to increase.

■ Why do three telecommunications pay attention to the field of quantum cancer communication?

Academia has raised concerns that if a quantum computer has been steadily emerging, the existing cryptocurrency system can be greatly threatened. Although quantum computers are still in research and development, there are many opinions that security technologies to prevent quantum computers should be completed before the appearance of quantum computers.

In particular, the importance of security is increasing in various areas such as the Internet of Things (IoT) and finance, and the research of urban aircraft mobility (UAM) by telecommunications companies is becoming more active, and quantum cryptography is attracting more attention. In order for the aircraft to move safely, smooth communication is essential.

Global market research firm BCC Research has also recently been $ 1.3 billion in 2024, from $ 347.2 million in 2019, from $ 347.2 million in 2019. I predicted that it would increase. According to BCC Research, the average annual growth rate of the quantum cryptography market is expected to reach 30.7%.

Professor Cheon Jung-hee, a professor at Seoul National University, said, When the quantum computer will be commercialized, opinions are mixed, but the impact of being practical is great. It's natural.

An official from the industry said, The reason why the research is not yet appeared, but the research is actively conducted in the field of password, because the yam, which is said to be difficult now, will move to an easy axis. He said.
