LG Uplus has developed the Q-PUF USB, a security chip supporting Post-Quantum Cryptography (PQC) technology. The Q-PUF USB employs technology with preventive measures against attacks from quantum computers. LG Uplusβ new security technology is developed in line with South Koreaβs Digital New Deal. LG Uplus developed the Q-PUF USB in collaboration with ICTK Holdings, a security solution provider.
βWe will complete an enhanced end-to-end security system that will completely prevent attacks from quantum computing by expanding quantum-resistant cryptography technology in next-generation 5G services such as remote control and telemedicine,β said Koo Sung-chul, head of the wired business of LG Uplus.
A quantum computer can easily solve and infiltrate a system that uses the RSA algorithm. However, a quantum computer would take billions of years to solve a system with a quantum-resistant encryption technique that applies complex mathematical algorithms.
By incorporating ICTK Holdingsβ hardware security devices, LG Uplus produced the Q-PUF, which is a USB security chip. The hardware technologies include the Quantum Random Number Generator (QRNG) and the Physically Unclonable Function (PUF). By exchanging data directly from one another, the QRNG and PUF prevent the privacy violation of customers.
Quantum-resistant encryption is vital to the operation of next-generation security technologies since they stop information leaks. It strengthens the service security in numerous equipment including drones, home appliances, electric vehicles, and corporate tools. Users can use the Q-PUF USB in cryptographic key exchanges and data encryption and authentication as well.
βThe application of unrivaled security technology from domestic ventures to next-generation 5G infrastructure security means a great deal of coexistence between technology ventures and large companies. I hope that it will become an exemplary case for building a 5G ecosystem,β said Lee Jeong-won, chief executive of ICTK Holdings.
Testing the commercial usefulness
Last December, LG Uplus organized a project testing the commercial usefulness of quantum-resistant cryptography technology. In collaboration with Cryptolab, LG Uplus applied the technology to a 640-kilometer connection line. The connection extended to data and medical centers along Pyeongtaek, Busan, Seoul, and Daejeon.Β Β
LG Uplus announced the PQC technology is convenient for hospitals and institutions that hold sensitive information. βPQC is an innovative technology that can provide security services to various terminal areas such as wireless networks, smartphones, and Internet of Things as well as wired networks,β said Koo.
