Action Items

Updates

• @Joshua Alexander

  • Boards work!!?? Tested VBAT, VDDD, GND with optical bootloader and ran frequency sweep with optical calibration and observed expected current profile from VBAT

  • Digicom (Mo) used low temperature solder and did not attach pin headers

  • N of 2

  • Next steps include DCDC, RF, and IMU testing

  • Need to establish method of low temperature pin header attachment, likely via silver epoxy

• @Mališa Vučinić

  • Presented the idea of his open PhD position in network security related to SCUM.

    • Research how changes in temperature affect the operation of the network.

    • With attackers controlling part of the nodes.

    • Mixed network SCUM - OpenMote

  • Opinions:

    • @David Burnett: They changes of SCUM over temperature is a good open question, that has applications in the medical field. (Insulin injector pen with a single chip with bluetooth that automatically tracks and report how much insulin you’re using and reports it to your Smartphone. Also must withstand quick change from freezing temperature to ambient temperature)

    • @David Burnett: Temperature detection of attacked node is part of the Machine Learning field of “Anomaly Detection“

    • @David Burnett: Another use case: Company trying to put SCUM inside a lightbulb. Therefore it needed to maintain its connection as it rapidly heated when the bulb is turned on.

    • @David Burnett: Another use case: Clock-glitching as a vector to attack a chip. Instead of injecting the faults with high power lasers, or bridging the clock line with your own signal, or using a sparkgap very close to the clock line. Try to inject these faults with rapid temperature changes.
