ICMetrics Platforms• As mentioned last time I’m looking over three

different ranges, PIC, Arduino & ARM processors.

Adaptable ICMetrics• The next version of the board will offer the

ability to show how the system reacts to new hardware

• Switches to allow for instant connection or current sensing pins for adaptable connections (similar to how your phone knows when to charge)

Latest Results• Identified three potential features:

– Program Counter– Processor Counter– Voltage

• Samples collected were based on original analysis of 1000.

Accuracy Graph• Graph showing accuracy vs samples

11 11Part-financed by the

Further Analysis• The number of samples can generate a different

mode• Was discovered by looking to reduce the

amount of samples due to limitations of embedded devices

12 12Part-financed by the

Program Counter

• Most stable between 216 and 639 samples & 641 to 999 samples

13 13Part-financed by the

Fund

Processor Counter• Three

distinct modes discovered

• The third mode is the most stable

14 14Part-financed by the

European Regional Development

Fund

Voltage• One mode

found over 1000 samples which is stable after 19 samples

15 15Part-financed by the

European Regional Development

Fund

Overall Result• Generation of modes using three different

features• Identifying the amount of memory required to

generate a stable mode

Future Work• Lille Conference paper in ICMetric security

fundamentals• EST Conference where we are going to publish

our first results• Targeting Journal publications
