USIM과 eSIM Evolution
eSIM can be used in connected cars (smart rearview mirrors, onboard diagnostics (OBD), vehicle Wi-Fi hotspots) as well as artificial intelligence translators, WiFi devices, smart earphones, smart metering, GPS tracking devices, DTUs, bike sharing, advertising players, video Widely applicable to various Internet of Things (IoT) scenarios, such as surveillance devices.
USIM and eSIM Evolution
The IoT device protects the IoT system with the Root of Trust function, and provides the eSIM function for subscriber authentication. Security and communication functions for connected IoT devices can be applied simultaneously using one chip.
Since secure communication is possible through the Root of Trust function, IoT devices with sufficient security level can be manufactured through system security, communication security, and device authentication in IoT devices.
To provide eSIM function, ISO/IEC 7816 interface is provided. It satisfies the low power requirements of eSIM and has specifications that can be applied to IoT devices powered by batteries without an external power source.
In addition, in order to respond to the era of future quantum computers, a hardware-based multiplier for accelerating the Post Quantum Cryptography (PQC) algorithm is mounted, and it has a function to accelerate the PQC algorithm when it is run on the chip.
In the future, NIST is designing and testing a subsequent chip that can support the algorithm that passed the final round in hardware.
