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 4 s-boxes in the ARIA and the 2 s-boxes are the same as
AES's s-boxes. The basic strategy is to use the aes-ni.
To calculate a 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 a 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 a third and fourth s-boxes, it uses the aesenclast,
then inverts shift_row, and affine transformation.
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.

+ ARIA cipher algorithm (RFC5794).
+
+ ARIA is a standard encryption algorithm of the Republic of Korea.
+ The ARIA specifies three key sizes and rounds.
+ 128-bit: 12 rounds.
+ 192-bit: 14 rounds.
+ 256-bit: 16 rounds.
+
+ This module provides the ARIA cipher algorithm that processes
