PUF Tech

PUF is a cutting-edge technology that creates a unique security key during the chip manufacturing process, at the micro-level.

This key is impossible to modify or duplicate.

PUF Tech


Physically Unclonable Function(PUF) is a cutting-edge technology that assigns a unique security key to each semiconductor chip by utilizing minute variations in the physical structure that occur during the chip manufacturing process, making it impossible to tamper with or duplicate. 

Product


All ICTK's products are based on PUF chips with strong security features. They are also available in modular form to meet the needs of different customer environments and conditions. Ultimately, these chips and modules can be supported as a comprehensive security solutions and IP.

Chips


Roots of trust are highly reliable hardware, firmware, and software components that perform specific, critical security functions. Because roots of trust are inherently trusted, they must be secure by design. As such, many roots of trust are implemented in hardware so that malware cannot tamper with the functions they provide. Roots of trust provide a firm foundation from which to build security and trust.

Modules


PUF chips can be molded into modules of the customer's choice. It can be shaped and molded to be more user-friendly, but its security features are much stronger. Currently, the main module lineup includes Wi-Fi modules, LTE/5G modules, Secure UICC, and Secure USB/PCI modules.

Solutions


The chips and modules come together and are finally delivered to customers as a solution. ICTK's security solutions are already in use in the market in various fields such as user authentication, FOTA, KMS, PQC, and VPN.

IP


It is the basis of the ICTK Root of Trust System and is mainly provided with other Security Elements. It is not IP in the form of hard macro of other companies like SRAM PUF, but soft IP provided in RTL. Flexible integration into any SoC configuration. The Root of Trust (RoT) is always the trusted root within a cryptographic system. Cryptographic systems use encryption keys to encrypt data and perform functions such as digital signature creation and signature verification.

Our Products


Based on security chips embedded with VIA PUF technology, a wide range of products, solutions, customizable modules, and IPs can be supported.


Chips

By implementing a hardware-based Root of Trust (HRoT) using a PUF security chip, enhanced security is ensured from the product design stage. To address the growing security threats posed by quantum computing, we offer advanced PUF security chips combined with Post-Quantum Cryptography (PQC).

Modules

PUF chips can be customized into modules—such as unclonable PQC-PUF SIM chips—according to customer environments and requirements, providing even stronger security.

Solutions

Our chips and modules come together and are finally delivered to clients as a solution. ICTK's security solutions are already in use in the market in across various fields such as user authentication, FOTA, KMS, PQC, and VPN.
