Ictk designs security chips that give connected devices a unique, hardware-level identity, acting like a fingerprint built into the silicon, so that IoT devices, mobile networks, and other systems can authenticate themselves without relying on software-stored keys that can be copied or hacked.
The company supplies its chips and security modules to mobile carriers and global technology companies, and is listed on KOSDAQ, South Korea's tech-focused stock exchange. Its core technology, called VIA PUF™, generates an unclonable identity from microscopic variations that occur naturally during chip manufacturing, and the company layers post-quantum cryptography on top of that hardware root of trust to address both current and future encryption threats.
