2016 PUF Mass-Produce & SaleICTK, PUF chip's first shipping ceremony

아이씨티케이(ICTK·대표 김동현)는 최근 성남시 판교 본사에서 물리적 복제방지(PUF) 칩 첫 출하식을 가졌다고 11일 밝혔다.

PUF 칩은 해킹 기술 발달로 보안에 한계가 있는 메모리 기반 보안 집적회로(IC)의 대안기술이다. PUF는 반도체 고유의 물리적 특성을 난수화해 암호화하는 기술이다. 그간 여러 기술 문제로 대량생산에 어려움을 겪었다.

ICTK는 2007년부터 PUF 연구에 착수했다. 2014년 대량생산이 가능한 PUF를 개발했다. 반도체 적층 공정에서 생기는 작은 구멍(VIA HOLE)을 활용해 난수화한 것이다.

ICTK는 PUF 설계, 제조, 최적화, 응용, 시스템 등 등록을 마친 국내외 특허만 37건에 이른다. 또 특허 88건을 출원해 등록을 기다리고 있다.

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.
