# pyecsca-notebook
**Py**thon **E**lliptic **C**urve cryptography **S**ide-**C**hannel **A**nalysis toolkit.
Notebook package, see below for description of the notebooks showcasing the toolkit.
See the [main repo](https://github.com/J08nY/pyecsca) for more information.
## Notebooks
### Configuration space
The [configuration space](configuration_space.ipynb) notebook explores the size of the space of
possible implementation configurations of ECC.
### Simulation
The [simulation](simulation.ipynb) notebook showcases the simulation and execution tracing capabilities
of the toolkit.
### Codegen & emulation
The [codegen](codegen.ipynb) notebook demonstrates the process of generating and interacting with
generated C implementations of ECC for micro-controllers. The generated implementations can either
be run on compatible hardware or emulated (at CPU-level) using the
[Rainbow](https://github.com/Ledger-Donjon/rainbow)-based emulator demonstrated in the
[emulator](emulator.ipynb) notebook.
### Measurement
The [measurement](measurement.ipynb) notebook demonstrates the trace acquisition using
PicoScope/ChipWhisperer scopes that can be used with the toolkit.
### Visualization
The [visualization](visualization.ipynb) notebook showcases the trace visualization capabilities
of the toolkit.
### Smartcards
The [smartcards](smartcards.ipynb) notebook shows the options of communicating with smartcard
targets using the toolkit.
### Reverse-engineering
#### RPA-RE
The [RPA](re/rpa.ipynb) notebook uses the Refined Power Analysis attack-based technique to reverse-engineer
the scalar multiplier of ECC implementations, given access to a power side-channel.
#### EPA-RE
The [EPA](re/epa.ipynb) notebook uses the ideas behind the Exceptional Procedure Attack to reverse-engineer
the coordinate system and formulas of ECC implementations, given access to an error side-channel.
#### ZVP-RE
The [ZVP](re/zvp.ipynb) notebook uses the Zero-Value Point attack-based technique to reverse-engineer
the coordinate system and formulas of ECC implementations, given access to a power side-channel.
#### Structural
The [structural](re/structural.ipynb) notebook explores the structure of scalar multiplers and addition
formulas for reverse-engineering purposes.
