The following repository contains the most up-to date implementation of the LEDAkem cryptosystem (website) according to the following directory structure:
A reference implementation of the LEDAkem. The reference implementation library does not provide a main() function, and is intended to be compiled and linked to a binary. The required NIST API is present in KEM/include/api.h The included makefile creates a statically linkable library. for the chosen security level and value of the N0 parameters. The available security levels match NIST categories, it is thus possible to compile the library, e.g., for category 1 and N0=2 as:
SL=1 N0=2 make
This directory contains boilerplate code to allow an implementor to generate a new set of KAT inputs and outputs (KAT_generation directory), and a small boilerplate performing synthetic performance benchmarks of the KEM (Benchmarking directory).
In both cases, the makefile will generate a binary for each combination of security category and number of circulant blocks N0 simply running
make
The KAT_generation also contains a script which allows the generation of fresh KAT for all the (security category, N0) pairs, named katgen.sh. Running the script with no parameters from the KAT_generation directory will call all the compiled binaries and generate the KATs.
