LG Uplus made an announcement on Dec. 27 that it has succeeded in developing a quantum security chip for IoT terminals for the first time in Korea with security system-on-chip (SoC) developer ICTK Holdings, an information security startup EYL, and LG CNS.

This is expected to further strengthen the security of IoT devices ranging from autonomous vehicles and drones to corporate and home CCTVs.

Quantum security is a technology that prevents duplication and prediction of encryption keys by generating unpredictable and patternless pure random numbers with "QRNG (Quantum Random Number Generator)."

Compared to TRNG (True Random Number Generator), which is a security technology used in existing IoT devices, it is safer from hacking threats due to the high randomness of passwords.

The three companies combined these QRNGs into a "PUF (Physical Unclonable Function)" and composed them as a "quantum security chip (CPUF).

QRNG and PUF send and receive data directly from each other within a chip. This will help customers prevent privacy violations and information leakage.

Each company expects that this quantum security chip can be applied to IoT devices that are actually being used as early as the first half of next year. Through this, the company plans to maximize the security of IoT devices that have become important recently.

PUF Technology

What is PUF?

Unique Inborn ID 
(PUF, Physically Unclonable Functions)

•Silicon Inborn ID using the randomness of passive device generation in the semiconductor manufacturing process

• As a Physical ID created with physical characteristics, it is fundamentally impossible to falsify or duplicate the value

• Since each semiconductor chip generates a different unique ID, it is called a semiconductor fingerprint.

PUF Advantages

AS Via PUF provides unique Silicon Inborn ID characteristics,  It provides the Root of Trust (RoT), the source of all trust

•Via PUF guarantees stability that is impervious to 
various types of hacking attacks.

•Via PUF is a method of forming via holes between 
metal layers during semiconductor processing.

•As a passive device method, it is an innovative method
that solves all the problems of existing technologies.

•PUF that satisfies all randomness, homeostasis and 
security •Unlike other technologies, no error correction
circuit (ECC) is required.

What you can do with PUF

VIA PUF can be applied to various IoT devices and solutions  that require strong security.

•ICTK's security chip generates a key pair of a private key and a public key in the security chip using an algorithm called ECC based on the key generated by PUF.

•ICTK's PUF security chip provides encrypted RAM (Random Access Memory) and encrypted eFlash (flash memory) inside.

•ICTK's security chip can be operated in PQC (Post Quantum Cryptography), a quantum security algorithm.

ICTK's security chip is the most powerful existing method to provide the Root of Trust function based on PUF.
