# Keccak-1600 for AVX2.
|
||
|
|
#
|
||
|
|
# July 2017.
|
||
|
|
#
|
||
|
|
# To paraphrase Gilles Van Assche, if you contemplate Fig. 2.3 on page
|
||
|
|
# 20 of The Keccak reference [or Fig. 5 of FIPS PUB 202], and load data
|
||
|
|
# other than A[0][0] in magic order into 6 [256-bit] registers, *each
|
||
|
|
# dedicated to one axis*, Pi permutation is reduced to intra-register
|
||
|
|
# shuffles...
|
||
|
|
#
|
||
|
|
# It makes other steps more intricate, but overall, is it a win? To be
|
||
|
|
# more specific index permutations organized by quadruples are:
|
||
|
|
#
|
||
|
|
# [4][4] [3][3] [2][2] [1][1]<-+
|
||
|
|
# [0][4] [0][3] [0][2] [0][1]<-+
|
||
|
|
# [3][0] [1][0] [4][0] [2][0] |
|
||
|
|
# [4][3] [3][1] [2][4] [1][2] |
|
||
|
|
# [3][4] [1][3] [4][2] [2][1] |
|
||
|
|
# [2][3] [4][1] [1][4] [3][2] |
|
||
|
|
# [2][2] [4][4] [1][1] [3][3] -+
|
||
|
|
#
|
||
|
|
# This however is highly impractical for Theta and Chi. What would help
|
||
|
|
# Theta is if x indices were aligned column-wise, or in other words:
|
||
|
|
#
|
||
|
|
# [0][4] [0][3] [0][2] [0][1]
|
||
|
|
# [3][0] [1][0] [4][0] [2][0]
|
||
|
|
#vpermq([4][3] [3][1] [2][4] [1][2], 0b01110010)
|
||
|
|
# [2][4] [4][3] [1][2] [3][1]
|
||
|
|
#vpermq([4][2] [3][4] [2][1] [1][3], 0b10001101)

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