|

| 21 | # 20 of The Keccak reference [or Fig. 5 of FIPS PUB 202], and load data
|
|---|
| 22 | # other than A[0][0] in magic order into 6 [256-bit] registers, *each
|
|---|
| 23 | # dedicated to one axis*, Pi permutation is reduced to intra-register
|
|---|
| 24 | # shuffles...
|
|---|
| 25 | #
|
|---|
| 26 | # It makes other steps more intricate, but overall, is it a win? To be
|
|---|
| 27 | # more specific index permutations organized by quadruples are:
|
|---|
| 28 | #
|
|---|
| 29 | # [4][4] [3][3] [2][2] [1][1]<-+
|
|---|
| 30 | # [0][4] [0][3] [0][2] [0][1]<-+
|
|---|
| 31 | # [3][0] [1][0] [4][0] [2][0] |
|
|---|
| 32 | # [4][3] [3][1] [2][4] [1][2] |
|
|---|
| 33 | # [3][4] [1][3] [4][2] [2][1] |
|
|---|
| 34 | # [2][3] [4][1] [1][4] [3][2] |
|
|---|
| 35 | # [2][2] [4][4] [1][1] [3][3] -+
|
|---|
| 36 | #
|
|---|
| 37 | # This however is highly impractical for Theta and Chi. What would help
|
|---|
| 38 | # Theta is if x indices were aligned column-wise, or in other words:
|
|---|
| 39 | #
|
|---|
| 40 | # [0][4] [0][3] [0][2] [0][1]
|
|---|
| 41 | # [3][0] [1][0] [4][0] [2][0]
|
|---|
| 42 | #vpermq([4][3] [3][1] [2][4] [1][2], 0b01110010)
|
|---|
| 43 | # [2][4] [4][3] [1][2] [3][1]
|
|---|
| 44 | #vpermq([4][2] [3][4] [2][1] [1][3], 0b10001101)
|

| 45 | # [3][4] [1][3] [4][2] [2][1]
|

| 46 | #vpermq([2][3] [4][1] [1][4] [3][2], 0b01110010)

|
|---|
| 49 | # [4][4] [3][3] [2][2] [1][1]
|
|---|
| 50 | #
|
|---|
| 51 | # So here we have it, lines not marked with vpermq() represent the magic
|
|---|
| 52 | # order in which data is to be loaded and maintained. [And lines marked
|
|---|
| 53 | # with vpermq() represent Pi circular permutation in chosen layout. Note
|

| 54 | # that first step is permutation-free.] A[0][0] is loaded to register of
|

| 55 | # its own, to all lanes. [A[0][0] is not part of Pi permutation or Rho.]

|

|

| 66 |
|

| 67 | # We also need to map the magic order into offsets within structure:

| 76 | # But on the other hand Chi is much better off if y indices were aligned

| 77 | # column-wise, not x. For this reason we have to shuffle data prior
