\"Patch-s\u00e6t <\/p>\n

Den 2. juni pr\u00e6senterede Eric Biggers (ingeni\u00f8r fra Google) nye implementeringer af AES-XTS for langt h\u00f8jere ydeevne p\u00e5 Intel\/AMD-processorer ved hj\u00e6lp af de nye instruktionss\u00e6t AES-NI + AVX, VAES + AVX2, VAES + AVX10\/256 og VAES + AVX10\/512.<\/p>\n

AES-NI GCM-koden erstatter den tidligere kode skrevet af Intel og l\u00f8ser eksisterende identificerede problemer:<\/p>\n

\n

Dette opdateringspakke tilf\u00f8jer en implementering af AES-GCM (Galois\/Counter-mode) til VAES og AVX512\/AVX10, hvilket \u00f8ger AES-GCM's ydeevne med op til 162%. Derudover erstatter det den tidligere AES-NI GCM-kode fra Intel med en ny kode, som er en smule hurtigere og retter en r\u00e6kke problemer, herunder den store bin\u00e6re filst\u00f8rrelse, der overstiger 250 KB. Se reparationerne for detaljer.<\/p>\n<\/blockquote>\n

\n

Den endelige tilstand af x86_64 AES-GCM assemblerkode er, at vi f\u00e5r to assemblerfiler: en, der genererer AES-NI-kode med eller uden AVX, og en anden, der genererer VAES-kode med AVX512\/AVX10 med 256-bit eller 512-bit vektorer. Den mangler support for enkelt VAES (uden AVX512\/AVX10). Dette adskiller sig lidt fra, hvad jeg gjorde med AES-XTS, hvor en fil genererer AVX- og AVX512\/AVX10-kode, herunder kode, der kun bruger VAES (uden AVX512\/AVX10), mens den anden fil kun genererer kode, der adskiller sig fra AVX. Dog synes dette p\u00e5 nuv\u00e6rende tidspunkt at v\u00e6re det rigtige valg for hver specifik algoritme, givet at begr\u00e6nsningen til 16 SIMD-registre og 128-bit vektorer har f\u00f8rt til nogle v\u00e6sentligt forskellige designsvarigheder i AES-GCM, men ikke s\u00e5 meget for AES-XTS. Processorer, der kun leveres med VAES, synes ogs\u00e5 at v\u00e6re et midlertidigt f\u00e6nomen, s\u00e5 vi b\u00f8r muligvis ikke str\u00e6be for meget efter at st\u00f8tte denne kombination.<\/p>\n<\/blockquote>\n
