Traditional IC Programming No Longer Meets IoT Security Needs

In complex connected environments, simple code writingcreates serious risks

No Built-in Security Protection

Standard programmers only copy data and cannot generate keys or inject certificates, making devices easy to clone, crack, or infect with malware.

High Production Line Cost

Secure UID and key injection requires on-site HSMs and network access, increasing cost and significantly reducing throughput (UPH).

Complex Certificate Management

Matter, AWS/Azure, and IEC 62443 all require different certificates per chip. Without automation, mass production is easily delayed.

Services

From Basic Programming to Secure Control

Three service levels for differentproduction stages
Level 1

Production Pre-Programming

Secure Pre-provisioning

Firmware and keys are programmed before shipment. No network or HSM required on your production line.

  • Ready to use
  • Lower security risk
  • Higher efficiency
Best for OEM / ODM
Level 2 (Popular)

IoT PKI Programming Consultant

PKI Strategy Consultant

We design and inject compliant certificate chains for Matter, automotive, and industrial standards.

  • Trusted certificate chain
  • Matter DAC generation
  • Certificate lifecycle control
Best for Brand Owners
Level 3

Cloud-Connected Programming

Cloud Connector

Cloud credentials are injected during programming, enabling devices to connect to AWS or Azure at first boot.

  • Direct AWS/Azure integration
  • JITR automation
  • Simplified development
Best for SI
Why CHANGINGTEC

Finance-Grade Security for Production Lines

E2E Encrypted

End-to-End Encrypted Programming (E2E)

Using secure tunneling, keys are encrypted throughout transmission from Ciot KMS to chips, ensuring zero-trust protection even in outsourced production.

Over-production Control

Anti-Counterfeit & Production Control

Real-time counters and authorized tokens strictly control chip programming quantity, preventing over-production and unauthorized products entering the market.

Chip Support

Supports Mainstream Chips & Security Elements

Wide support for MCU, Secure Element (SE), and PUF chips. No need to change programming vendors to meet different product line requirements.

KMS Server

Secure Tunnel

Secure Chip

Injected Certificates:
  • Device Private Key
  • X.509 Certificate (Matter/AWS)
Integration

Enterprise-Grade Security System Integration

Deeply integrate programming services into your security governance framework for automated management
KMS

KMS Key Management System Integration

Supports integration with your enterprise KMS. Key lifecycle (generation, rotation, revocation) is fully managed by your central system, while programmers serve only as trusted endpoints.

  • Supports HSM key import
  • Centralized access control
CodeSign

CodeSign Firmware Signing Service

Ensures firmware integrity and authenticity. Automatically verifies code signing before programming to prevent unauthorized or tampered firmware from being written to chips.

  • Prevents malicious firmware injection
  • Complies with OTA update security standards
