SK Telecom makes quantum leap in IoT security

South Korean operator SK Telecom has developed a prototype of an ultra-small quantum random number generator (QRNG) chip packed with entropy source and deterministic random bit generator (DRBG).
 
A QRNG generates true random numbers without any kind of pattern, meaning it is suitable for use in cryptography. However, so far, the cost and size of QRNGs on market have prevented them from becoming widespread.
 
With the successful development of a QRNG chip measuring 5 by 5mm, SK Telecom expects that it will soon be able to embed QRNG in a wide variety of IoT products, including autonomous vehicles, drones and smart devices, to enhance the level of security for IoT services. Although the price of each QRNG chip has not been set yet, the company said it would be the lowest price ever for a QRNG.
 
Meanwhile, SK Telecom is also developing a QRNG in the form of USB and PCIe. While the QRNG chip has to be embedded from the beginning of the product development, QRNG in the form of USB or PCIe can be connected to any product already on market to provide genuine randomness.
 
“Understanding the importance of data and data security, SK Telecom has focused on developing quantum cryptography technologies to guarantee secure transmission of data in areas including artificial intelligence, IoT and autonomous driving,” said Park Jin-hyo, senior vice president of SK Telecom. “We will continue to work with partners, both home and abroad, to accelerate the popularisation of quantum cryptography and strengthen our presence in the global market.”
