LG Uplus Develops World's First Ultra-Compact Enhanced Security eSIM

[Asia Economy Reporter Joesulgina] LG Uplus announced on the 4th that it has jointly developed the world's first ultra-small embedded subscriber identification module (eSIM) applying the 'Physical Unclonable Function (PUF)' with ICTK Holdings.

This technology enhances security by utilizing PUF technology, which uses the 'Inborn ID,' also known as the 'semiconductor fingerprint,' based on microscopic structural differences in semiconductors that make replication or alteration impossible. It integrates PUF technology and subscriber authentication functions into a single chipset. When the PUF-eSIM encrypts authentication keys and data, it enables not only subscriber authentication during LTE network access but also ▲blocking the execution of tampered firmware during device boot ▲strengthening end-to-end (E2E) secure communication between the device and server.

The size of the PUF-eSIM is only 6㎟ (2mm width x 3mm height), which is about 1/18th the size of a nano SIM used in smartphones. Thanks to its small size, it can be utilized in various fields such as wearable and industrial devices. It has obtained the AEC-Q100 certification from the Automotive Electronics Council, making it suitable for automotive use. The manufacturing cost has also been reduced by 30% compared to existing eSIMs.

LG Uplus plans to pursue acquiring the national official security certification, Cryptographic Module Validation Program (K-CMVP), to expand the use of PUF-eSIM in the public sector.

Jeon Young-seo, Head of Corporate Service Development at LG Uplus, said, "This product has high competitiveness not only due to subscriber authentication but also because of enhanced security and small size," adding, "We will expand PUF-eSIM across the wireless Internet of Things (IoT) business area and strive for wide distribution to maximize price competitiveness."

Lee Jung-won, CEO of ICTK Holdings, stated, "eSIM provides device identification and various functions, making security extremely important. This opportunity has laid the foundation for the company and Uplus to jointly propose standards leading the global standard of PUF-based Root of Trust."
