Implementation of ASCON Cryptography Algorithm for RISCV ISA with GCC Built-ins

This repository implements Ascon Cryptography algortihm for RISCV ISA. S-box and rotation operations are made with special RISC-V instructions, sbox and rot.

Prerequisites

1. RISCV GNU Toolchain should be installed for riscv64-unknown-elf-gcc compiler
2. Spike and pk should be installed for simulating compiled elf binary. (pk should be installed for RV32)
