⌚ Cryptographic Network Security: Apple Watch Audio Streaming AI Assistant (March 2026)

Watch the Apple Watch Demo

Github .md post

Designed and implemented a defense-in-depth security stack for real-time audio streaming between an Apple Watch and a home server.

  • AES-128-GCM encrypted UDP transport with cryptographic nonce derivation and replay protection via sequence numbers
  • Certificate-based identity using the Apple Watch Secure Enclave (private key never leaves hardware)
  • Three-port architecture separating enrollment, session auth, and media transport
  • Integrated LangGraph AI assistant as the application layer
