IoMTOps: 持续资产特征指纹提取、自动化 CVE 漏洞修复与临床零中断管理

IoMTOps Cryptographic Fleet Lifecycle & OTA Distribution Pipeline

Firmware signing enclave, canary rollout controller, and hospital validation checkpoint

Central System: Fleet Orchestrator - A/B Dual-Bank Rollout Engine

Clinical IoMT Nodes

• Hardware Signing HSM
• Fleet Health Telemetry Sink
• Canary Rollout Controller
• Dual-Bank Bootloader
• ISO 13485 Audit Logger

Architectural Layers & Regulatory Standards

• Cryptographic Signing & Integrity Verification (FIPS 140-3 Level 4 HSM / Ed25519 Signatures): Signing medical firmware binaries and verifying signatures prior to execution on clinical microcontrollers.
• Fleet Telemetry & Predictive Maintenance (MQTT-SN over TLS / CoAP Telemetry Agents): Continuously ingesting battery degradation curves, sensor calibration offsets, and error registers.
• Fail-Safe Over-The-Air Update Engine (Dual-Bank A/B Flash Memory Partitioning): Deploying updates without disrupting active therapy; instant fallback to golden image upon self-test fault.
• Regulatory Device History Record (DHR) (Immutable Ledger / Automated DHR Generation): Recording firmware version, build hash, clinical site, and patient device serial numbers.

Key Metrics: 100% (Dual-Bank Rollback Guarantee) | Zero Downtime (During Patient Telemetry) | FIPS 140-3 (Cryptographic HSM Enclave) | ISO 13485 (Validated QMS Automation)
