The implementation is based on the 32-bit implementation of the aria. Also, aria-avx process steps are the similar to the camellia-avx. 1. Byteslice(16way) 2. Add-round-key. 3. Sbox 4. Diffusion layer. Except for s-box, all steps are the same as the aria-generic implementation. s-box step is very similar to camellia and sm4 implementation. There are 2 implementations for s-box step. One is to use AES-NI and affine transformation, which is the same as Camellia, sm4, and others. Another is to use GFNI. GFNI implementation is faster than AES-NI implementation. So, it uses GFNI implementation if the running CPU supports GFNI. There are 4 s-boxes in the ARIA and the 2 s-boxes are the same as AES's s-boxes. To calculate the first sbox, it just uses the aesenclast and then inverts shift_row. No more process is needed for this job because the first s-box is the same as the AES encryption s-box. To calculate the second sbox(invert of s1), it just uses the aesdeclast and then inverts shift_row. No more process is needed for this job because the second s-box is the same as the AES decryption s-box. To calculate the third s-box, it uses the aesenclast, then affine transformation, which is combined AES inverse affine and ARIA S2. To calculate the last s-box, it uses the aesdeclast, then affine transformation, which is combined X2 and AES forward affine. The optimized third and last s-box logic and GFNI s-box logic are implemented by Jussi Kivilinna. The aria-generic implementation is based on a 32-bit implementation, not an 8-bit implementation. the aria-avx Diffusion Layer implementation is based on aria-generic implementation because 8-bit implementation is not fit for parallel implementation but 32-bit is enough to fit for this.
