Implementation of Barreto's curve "Curve13318" for ARM Cortex M4. This code is written for the STM32F407 device. The arithmetic used in this code is that of https://eprint.iacr.org/2018/286.
# Install rust toolchain manager
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Set up rust
rustup toolchain install nightly-2019-07-01
rustup target add --toolchain nightly-2019-07-01 thumbv7em-none-eabi
rustup override set nightly-2019-07-01
# Build the project (takes a while)
cargo build --release
# Connect your ARM board now. Make sure you have user access; you can use the
# file listed below to achieve this.
# Launch openocd in a separate terminal
openocd --file openocd.cfg
# Run the project
cargo run --release
# GDB will automatically set a breakpoint on `Reset`, so we have to tell it
# to continue immediately.
>>> continue
# Now the benchmarking output should appear in the openocd console
If there is something that does not work, you may want to take a look at
.cargo/config. This file specifies how the code is being run. You can update
parameters here; for example the path to GDB.
Udev rules for allowing user access to st-link devices. Path:
/etc/udev/rules.d/70-st-link.rules.
# STM32F3DISCOVERY rev A/B - ST-LINK/V2
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", TAG+="uaccess"
# STM32F3DISCOVERY rev C+ - ST-LINK/V2-1
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374b", TAG+="uaccess"
You can run this code on other thumbv7em-none-eabi devices! To achieve this, you will need to update the memory mapping to your own device in memory.x.
If you want to run the code on the thumbv7em-none-eabihf architecture, you
will need to update .cargo/config. We did not test this.
In any case, the setup is based on Jorge Aparicio's excellent guide on how to set up Rust with ARM Cortex. You can find it at https://rust-embedded.github.io/cortex-m-quickstart/cortex_m_quickstart/.
