Device Provisioning Workflow
Create a unique, auditable device identity and inject only the minimum required configuration.
Arduino-compatible frameworks, ESP-IDF/FreeRTOS, PIC/AVR/STM32/RP-class systems; apply exact vendor documentation for the selected MCU.Architecture
Approved work order → serial allocation → identity/key provisioning → verification → signed manufacturing record.
Security and recovery risks
- Never use one shared production secret across all devices.nDo not expose private keys in logs or exports.nRestrict provisioning authorization and retain audit evidence.
Implementation procedure
- Define serial-number format and collision prevention.nBind identity to hardware revision and product.nProvision per-device credentials using controlled tooling.nRead back only non-secret identifiers for verification.nRecord operator, station, time and result.
Starter code / configuration
{"serial":"TCSP-000001","product":"TCS-NODE","hardware":"A1","status":"provisioned"}Verification evidence
| Test | Expected | Evidence |
|---|---|---|
| Nominal boot | Correct version and hardware revision reported | Captured boot log |
| Fault recovery | Defined safe state and reset reason | Fault-injection record |
| Power cycle | No corrupt configuration or unsafe output | Repeated-cycle log |
Required release artifacts
- Versioned firmware binary and SHA-256
- Source revision / build identifier
- Board and hardware-revision compatibility list
- Test report and known limitations
- Recovery image and factory-reset procedure
- Provisioning/calibration schema
- Release approval record
