WearableHSM Miniaturized Architecture

Cryptographic Enclave: Wearable Cryptographic Core — Sub-Milliwatt IoMT Enclave

Hardware Security Nodes & Co-Processors

  • NIST ASCON-128 Hardware Core
  • PPG / ECG Biometric Seed Harvester
  • BLE 5.4 Secure Channel Engine
  • Health Telemetry Packet Authenticator
  • Ultra-Low-Power Deep Sleep Controller

Architectural Layers & Silicon Defenses

  • Layer 1: Miniaturized Micro-Die Silicon (Wafer-Level Chip-Scale Package (WLCSP)): Fitting into ultra-compact smart rings and flexible medical adhesives with footprint under 2.5 mm².
  • Layer 2: NIST Lightweight Cryptography Core (ASCON-128 / ASCON-Hash / AES-CCM): Executing authenticated encryption across continuous vital signs with 80% lower energy than standard AES.
  • Layer 3: Biometric Entropy & Physiological Key Derivation (Heart-Rate Variability (HRV) Extractor): Deriving dynamic ephemeral encryption keys from patient physiological metrics and internal PUFs.
  • Layer 4: Low-Energy Wireless Telemetry Gateway (Bluetooth Low Energy 5.4 / NFC / Thread): Transmitting encrypted health telemetry packets to mobile health apps and clinical base stations.

Cryptographic Telemetry & Compliance: < 80 nA (Deep Sleep Standby Current) | ASCON-128 (NIST Lightweight Standard) | < 2.5 mm² (Silicon Micro-Die Footprint) | 100% (BLE Man-in-the-Middle Defense)

面积小于2平方毫米的企业级密码防御

Smartwatches, biometric rings, and continuous glucose monitors (CGM) collect massive volumes of private health metrics while operating on tiny coin-cell or flexible batteries. WearableHSM shrinks hardware security modules down to micro-die dimensions, delivering authenticated encryption, biometric seed derivation, and BLE pairing protection with sub-milliwatt power draw.
