LG Uplus announced on January 19 that it has developed a "Q-PUF USB", a USB-type security token, containing Post Quantum Cryptography (PQC) technology to prevent attacks from quantum computers and applied it to its digital New Deal business.
"Q-PUF USB" is a USB security token created by combining ICTK Holdings' hardware security technologies, Physically Unclonable Function (PUF) and Quantum Random Number Generator (QRNG).
In the era of quantum computing, authentication technology that recognizes what to perform encryption communication and verifies that data is not manipulated becomes important.
LG Uplus has developed "Q-PUF USB" by upgrading quantum-resistant algorithms that will solve security threats when authenticating.
Quantum-resistant encryption is an encryption method that uses complex mathematical algorithms that take billions of years to solve using quantum computers. RSA encryption method can be easily solved by quantum computers, so next-generation security technologies such as quantum-resistant encryption are needed.
It can be applied to key elements of security such as cryptographic key exchange, data encryption, and integrity authentication, and can be implemented only with software without any separate equipment.
This allows flexible application from mobile phones to small IoT devices to provide security in all areas of wired and wireless networks.
LG Uplus develops small built-in subscriber identity module for devices
LG Uplus, a mobile carrier in South Korea, has teamed up with a transaction and security solution provider to develop a small built-in subscriber identity module featuring a physically unclonable function.
