Curve point decompression
by Wim Lewis 10 Nov '21

10 Nov '21

I'm looking at implementing elliptic curve point compression a la SEC1 (admittedly, mostly to reduce the number of "feature not supported" code paths in a library, but it seems like a somewhat useful ability). Nettle/Hogweed already implements it internally for curve25519, but I want to implement it for the "secp" curves as well. Point compression is easy enough, but point decompression requires some curve math, potentially dependent on the specific curve, and some of it is redundant with what's already done in ecc_point_set(). So I was thinking about moving this functionality into Hogweed as a function along the lines of ecc_point_set_compressed(), which would take, instead of a y-coordinate, an int containing the sign/parity of the y-coordinate. So my question for the list and for the maintainers is, is this a reasonable API to add to Hogweed? Is there interest in including it in Hogweed if I were to take the time to turn it into a tidy patch?

Add ppc64le arch to Gitlab CI
by Maamoun TK 21 Jul '20

21 Jul '20

I investigated this issue. The Debian image used for Gitlab CI only supports the following archs amd64 mips armhf arm64. To add a new arch, this arch should be added to the sources list of apt and install the required packages to build and check nettle library.

[Patch] Optimize AES and GHASH for PowerPC64 (support little-endian and big-endian)
by Maamoun TK 01 Jul '20

01 Jul '20

Patch implementation benchmark for GCM_AES (Tested on POWER8): little-endian: - Encrypt x~17.5 of nettle C implementation - Decrypt x~17.5 of nettle C implementation - Update x~30 of nettle C implementation big-endian: - Encrypt x~18.5 of nettle C implementation - Decrypt x~18.5 of nettle C implementation - Update x~28.5 of nettle C implementation I investigated falling back to process 4 blocks instead of 8 blocks, 8x loop outperform 4x loop by x~1.22 on POWER8. Processing 4 blocks leaves plenty of registers on the table, to reduce the performance margin these registers can be used to overlap the instructions inside the loop. GHASH loop has two separate operations: - Digest calculation - Reduction The reduction procedure is hardly parallelized, to overcome that, the two procedures can overlap as follows |`````````````````````````````````````````| |Head: | |Digest calculation [0..3] | |`````````````````````````````````````````| |Loop: | |Overlapped Reduction [i+0..i+3] and | |Digest calculation [i+4..i+7] | |`````````````````````````````````````````| |Tail: | |Reduction [i+4..i+7] | ``````````````````````````````````````````` With that implemented the performance margin is reduced to x~1.15 and the code is messed up a little bit I can do more documentations so the reader can still keep track of what's going on but with that said the performance margin is still considerable and I think it's better to stick with 8x loop. - The patch passed the testsuite for both ppc64 and ppc64el. --- Makefile.in | 2 +- asm.m4 | 17 +- config.m4.in | 1 + configure.ac | 12 + gcm.c | 19 +- powerpc64/aes-decrypt-internal.asm | 584 +++++++++++++++++++++ powerpc64/aes-encrypt-internal.asm | 545 +++++++++++++++++++ powerpc64/gcm-hash8.asm | 1015 ++++++++++++++++++++++++++++++++++++ powerpc64/machine.m4 | 0 testsuite/gcm-test.c | 23 + 10 files changed, 2214 insertions(+), 4 deletions(-) create mode 100644 powerpc64/aes-decrypt-internal.asm create mode 100644 powerpc64/aes-encrypt-internal.asm create mode 100644 powerpc64/gcm-hash8.asm create mode 100644 powerpc64/machine.m4 diff --git a/Makefile.in b/Makefile.in index 64ff1001..fdc819f1 100644 --- a/Makefile.in +++ b/Makefile.in @@ -603,7 +603,7 @@ distdir: $(DISTFILES) done set -e;

[PATCH] Add ppc64 and ppc64el to Gitlab CI
by Maamoun TK 30 Jun '20

30 Jun '20

To run tests on ppc64 and ppc64el, this patch install cross building packages for both architectures on the Debian image, these packages will be install every time the CI triggered. A proper fix would be to install these packages to the image directly. This patch follows a different approach to get access LD shared library for qemu. Other architectures install native libc6 packages while both ppc64 and ppc64el install cross libc6 packages and export QEMU_LD_PREFIX to point to LD path which is more reasonable. .gitlab-ci.yml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 9f3b5c63..7f12ecfa 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -139,6 +139,11 @@ Debian.cross.x86: before_script: # remove any previously installed nettle headers to avoid conflicts - for arch in armhf mips arm64;do apt-get remove -y nettle-dev:$arch;done + - host="${CI_JOB_NAME#*.cross.}" + - if [ "$host" == "powerpc64-linux-gnu" ];then apt-get update && apt-get install -y gcc-$host && + apt-get install -y g++-$host && apt-get install -y libstdc++6-ppc64-cross && export QEMU_LD_PREFIX=/usr/$host;fi + - if [ "$host" == "powerpc64le-linux-gnu" ];then apt-get update && apt-get install -y gcc-$host && + apt-get install -y g++-$host && apt-get install -y libstdc++6-ppc64el-cross && export QEMU_LD_PREFIX=/usr/$host;fi script: - build=$(dpkg-architecture -qDEB_HOST_GNU_TYPE) - host="${CI_JOB_NAME#*.cross.}" @@ -162,3 +167,7 @@ Debian.cross.mips-linux-gnu: <<: *Debian_cross_template Debian.cross.aarch64-linux-gnu: <<: *Debian_cross_template +Debian.cross.powerpc64-linux-gnu: + <<: *Debian_cross_template +Debian.cross.powerpc64le-linux-gnu: + <<: *Debian_cross_template

FYI: Forced update of master-updates
by nisse＠lysator.liu.se 27 Jun '20

Hi, I tried out a microoptimization of the arm neon implementation of chacha and salsa20. Gave a 10% speedup on the older Cortex-A5 core, but unclear if it's an improvement overall, so I don't want to push it to master, and I've removed that commit from master-updates (now on its own branch arm-salsa20-chacha-vsra instead, in case anyone is curious). I'm considering changing the internal _salsa20_core and _chacha_core to do more than one block at a time, since processing a few blocks in parallel has a great potential for performance improvements.
