Slide 2

Part-financed by the European Regional Development Fund Plan of presentation I. Outline of the task within the context of the project II. Main results III. Future challenges and the work to be done 2

Slide 3

Part-financed by the European Regional Development Fund ICMetrics Platforms As mentioned last time Im looking over three different ranges, PIC, Arduino & ARM processors. 33

Slide 5

Part-financed by the European Regional Development Fund Summary Hardware: Custom made board with PIC32 processor MPLab debugging/complier Programming: C (MPLab) Analysis: Matlab 55

Slide 6

Part-financed by the European Regional Development Fund Next revision Display Module SD Card Module Pins for future modules 66

Slide 7

Part-financed by the European Regional Development Fund ICMetrics Board v1.2 77

Slide 8

Part-financed by the European Regional Development Fund 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) 88

Slide 9

Part-financed by the European Regional Development Fund Latest Results Identified three potential features: Program Counter Processor Counter Voltage Samples collected were based on original analysis of 1000. 99

Slide 10

Part-financed by the European Regional Development Fund Accuracy Graph Graph showing accuracy vs samples 10

Slide 11

Part-financed by the European Regional Development Fund 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 11

Slide 12

Part-financed by the European Regional Development Fund Program Counter 12 Most stable between 216 and 639 samples & 641 to 999 samples

Slide 13

Part-financed by the European Regional Development Fund Processor Counter 13 Three distinct modes discovered The third mode is the most stable

Slide 14

Part-financed by the European Regional Development Fund Voltage 14 One mode found over 1000 samples which is stable after 19 samples

Slide 15

Part-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 15

Slide 16

Part-financed by the European Regional Development Fund Future Work Lille Conference paper in ICMetric security fundamentals EST Conference where we are going to publish our first results Targeting Journal publications 16
