Highlights

What sets it apart.

01

Designed and manufactured domestically, with control over the entire supply chain

02

AES-256, RSA-2048 and ECC encryption on the chip itself

03

Physical tamper-detection mesh, with an anti-counterfeiting response in under 1 second

04

Biometric authentication performed on the card itself; data does not leave the chip

05

CC EAL5+ and FIPS 140-1 certified

Overview

Public Security Smart Card Chip

Why chip design must be mastered in-house

The chip is where the secret keys of the entire national identification system are held. If it is imported as a finished unit, there is no way to be fully certain that the design contains no backdoors or deliberate flaws. Designing and manufacturing it domestically is the only way to control this.

Manufacturing process

  • Advanced photolithography of silicon wafers
  • Ultra-precise chip mounting
  • Ultra-fine wire bonding and module packaging
  • Comprehensive testing and card personalisation

Security at the physical layer

Beyond encryption, the chip integrates a tamper-detection mesh covering its surface. When physical interference is attempted in order to read its contents covertly, the chip responds in under one second — a mechanism that software alone cannot replace.
