Kyber-ARM

This repository contains the reference implementation of the Kyber key encapsulation mechanism, Post Quantum Cryptography algorithms for the ARM64 architecture.

Build

To build the project you should use a bash script build.sh for which you should use cmake: Optionaly, you can set bitness of application by "-b=" option. Default is x32

./build.sh -b=64

or,

./build.sh -b=32

The build result will be available in the /build/ref directory.

Usage

To use the Kyber functions in your project, you must use the static libs that are located in the /build/ref directory. For example:

#include "<path_to_kyber_kef_directory>/kem.h"

int main(void)
{
    int rc = 0;
    unsigned char pk[32] = { 0 };
    unsigned char sk[32] = { 0 };

    rc = crypto_kem_keypair(pk, sk);

    return rc;
}
export CC=/<absolute_path_to_toolchain>/bin/aarch64-linux-gnu-gcc
$CC -DKYBER_K=2 -c your_app.c
$CC -o binary your_app.o -L. -lkyber512_ref.a

Cross-compile is located in toolchain directory of this repository.

Testing

  1. Copy ./build/speed_test.tar.gz on Raspberry PI
  2. Untar on board tar xzvf speed_test.tar.gz
  3. cd speed_test
  4. sudo ./install_module.sh
  5. sudo ./test.sh

For tests you can use ./runtests.sh script. Don't forget that the tests must be run either in the emulator or on the target platform.
