GLS254 repository

The code repository for the paper "2DT-GLS: Faster and exception-free scalar multiplication in the GLS254 binary curve": https://eprint.iacr.org/2022/748

Project structure

• arm - Armv8 AArch64 implementation of GLS254, with runnable tests and benchmarks.
• sage - Sage implementation of the group law formualas and scalar multiplication algorithms. Reports operation counts.
• x64 - 64-bit Intel implementation of GLS254, containing code previously submitted to SUPERCOP
