Identity based networking for embedded systems



Introduction:

Execution view of a TrustZone enabled ARMv8-M processor core.


A code sequence with good auto-correlation properties yields a Gaussian-distribution of cross-correlation scores.

Recording cash mode’s ‘near-ultrasound’ signal.


  1. Precision farming or agriculture.
  2. Industrial inspections.
  3. 3D terrain mapping and image processing
  4. Border defense
  5. Hyper-local delivery (including medical supplies)


The esp32 (IoT) board connected to a 0.50$ crypto-processor (atecc608a)

The goal— Evaluate how one could vastly improve security in any IoT project with just 0.50$. (yes, including that 10$ thing that has no business being connected to the internet.)

  1. You need a unique device identity to securely — ‘authenticate your device’
  2. You need to make sure the code on your device is what you expect it to be — ‘firmware validation aka secure boot’
  3. You need to know that people can’t make (illegitimate) copies of your devices…


Quite the attention grabber!
