Detailed Description

template<int mul>
class fss::prg::Aes128MmoRaw< mul >

AES-128 with Matyas-Meyer-Oseas and AES-NI intrinsics as a PRG.

Host-only. Device use of Gen(), GenHalf(), or Gen8() fails to build with an unresolved-extern error naming fss_host_only_Aes128MmoRaw_used_in_device_code.

Template Parameters

mul	See Prgable mul.

Constructor & Destructor Documentation

Aes128MmoRaw()

template<int mul>

fss::prg::Aes128MmoRaw< mul >::Aes128MmoRaw ( const uint8_t keys[][16] )

inline

Constructor.

Parameters

keys	mul 16-byte AES-128 keys.

Gen8()

template<int mul>

cuda::std::array< cuda::std::array< int4, mul >, 8 > fss::prg::Aes128MmoRaw< mul >::Gen8 ( cuda::std::span< const int4, 8 > seeds )

inline

Batched 8-seed version of Gen().

Applies the same MMO construction to 8 independent seeds under the same key schedules, so out[j] is bit-exact with Gen(seeds[j]). The 8 streams are interleaved as 8 x 128b lanes: each AES round key is loaded once and consumed by 8 consecutive aesenc calls.

Only for host side.

See the HasGen8 concept for the effect on the schemes that batch their PRG expansion through this member and for when a backend gains from it.

Parameters

seeds

8 independent 16B seeds.

Returns

For each seed j, the mul MMO output blocks out[j][i] = E_{keys[i]}(seeds[j]) ^ seeds[j].

GenHalf()

template<int mul>
requires (mul > 0 && mul % 2 == 0)

cuda::std::array< int4, mul/2 > fss::prg::Aes128MmoRaw< mul >::GenHalf ( int4 seed, bool right )

inline

Return the selected half of Gen() with the same call requirements.

Parameters

seed	Seed block to expand, the same input Gen() takes.
right	false selects the first half, true selects the second half.
