South Korea 5g quantum encryption technology officially commercial, is it really leading or not

Recently, in the period of 5g construction and expansion, another more powerful news came out of the industry. South Korea will use 5g quantum encryption technology next month. It is understood that the news that 5g quantum encryption technology will soon be applied in South Korea is announced by SK Telecom, the largest telecom operator in South Korea, on its official website. Sk Telecom also said on its official website that the mobile banking application “Im bank” of Daegu bank will adopt their 5g quantum encryption technology, which will be launched in September. < / P > < p > in addition, “Im bank” will be the first banking service supported by Quantum services in the global banking industry. Smart phone users of Samsung Galaxy a quantum equipped with quantum random number generator chipsets will have a higher level of security when using “Im bank”. When this news came out, many people felt that it was a little unreliable. After all, there have been too many hoaxes about quantum technology before. Online make complaints about quantum mechanics. < / P > < p > so, is SK Telecom really having a super leading black technology, or is it trying to hype it? Or is it that South Korea secretly makes up lessons behind the back of the whole world, or is it that the matter itself has no mystery? < / P > < p > in fact, after a wave of hype about the concept of quantum technology last year, many people probably know that quantum technology is still an advanced concept. Its implementation difficulty and huge research cost determine that it is very “cold” and far away from public life. < / P > < p > and carefully analyzing the news of SK Telecom’s high-profile announcement of 5g quantum encryption technology, we also found another familiar protagonist Samsung Galaxy a quantum mobile phone. < / P > < p > as you know, on May 14, this year, Samsung and SK Telecom launched the galaxy a quantum mobile phone, the world’s first 5g smartphone with a quantum random number generator chipset. At the time of its release, the price was 649000 won, about 530 US dollars and 3758 yuan RMB, and was only exclusive to sk Telecom, a Korean operator. < / P > < p > but now this mobile phone has basically no news to see. Mobile phone 5G as like as two peas Galaxy A71 5G, which is identical to Galaxy A Quantum, is visible in the market. However, according to the details announced by Samsung, this so-called quantum encryption mobile phone is actually carrying a quantum random number generation chip developed by SK Telecom on the Samsung Galaxy a715g mobile phone to realize encryption information. Experts in the industry have learned that the so-called quantum random number generator QRNG has little to do with the principles of quantum mechanics, but is more based on the principles of quantum cryptography. In short, it is to generate pseudo-random numbers based on algorithms or extract random numbers from classical physical noise by computer simulation. Then, random number generation is used to encrypt the data transmitted on the Internet. The quantum random number generation chip developed by SK Telecom uses the shot noise of light source captured by CMOS image sensor to generate random sequence, and encrypts the information by measuring the random number obtained by the quantum state. < / P > < p > this is not a new technology, it can only be called the edge ball of quantum communication. However, the ability to carry QRNG chips on smart phones is not a small technological progress. < / P > < p > it is understood that in 2017, compared with smart phones, the volume of QRNG chips was relatively large, and the price was in the hundreds to thousands of dollars. Sk Telecom laid out quantum communication related technologies many years ago, and became the controlling party of ID quantique, a Swiss quantum cryptography company, by acquiring more than 50% equity in 2018. From this point of view, SK Telecom of South Korea announced that 5g quantum encryption technology will be used for commercial use. It may be that they want to rub off the high-tech sense of quantum technology to promote their own QRNG chips and related applications to banks and money industry. However, the 5g quantum encryption technology in SK Telecom in South Korea is obviously far from the quantum technology in the scientific and technological circles and the public. In addition, it is worth mentioning that the quantum encryption technology will have a reconfigurable change to the existing encryption technology. Therefore, in the application scenarios and industries that attach great importance to information security such as finance, banking, communication, government affairs, its future value will not be lower than that of cloud computing.
