In addition, the libOTe build script/cmake will output many of the dependency while the remaining will be located in the build directory. ## Help diff --git a/build.py b/build.py new file mode 100644 index 00000000..03b6e640 --- /dev/null +++ b/build.py @@ -0,0 +1,10 @@ +import cryptoTools.build +import sys + + + +if __name__ == "__main__": + if(len(sys.argv) > 1 and sys.argv[1] == "setup"): + cryptoTools.build.Setup() + else: + cryptoTools.build.Build() diff --git a/build.sh b/build.sh deleted file mode 100644 index fea66985..00000000 --- a/build.sh +++ /dev/null @@ -1,18 +0,0 @@ -#!/bin/bash - -mkdir -p out -mkdir -p out/build -mkdir -p out/build/linux - -cd out/build/linux - - -#if [ ! -f ./Makefile ] || [ "$#" -ne 0 ]; then -#fi - cmake ../../.. $@ - - -make -j - - -cd ../../.. \ No newline at end of file diff --git a/cryptoTools b/cryptoTools index 30853672..2aa8819e 160000 --- a/cryptoTools +++ b/cryptoTools @@ -1 +1 @@ -Subproject commit 308536722231f95fc6446170f3e29f26cb7a8222 +Subproject commit 2aa8819e80fef126f509f4511c209ce15fb1d2d8 diff --git a/libOTe/CMakeLists.txt b/libOTe/CMakeLists.txt index 35f2785c..6f6068ab 100644 --- a/libOTe/CMakeLists.txt +++ b/libOTe/CMakeLists.txt @@ -12,7 +12,7 @@ target_include_directories(libOTe PUBLIC "${CMAKE_CURRENT_BINARY_DIR}/..;${CMAKE target_link_libraries(libOTe cryptoTools) if(MSVC) - target_compile_options(libOTe PRIVATE -openmp:experimental) + #target_compile_options(libOTe PRIVATE -openmp:experimental) else() if(ENABLE_SSE) diff --git a/libOTe/TwoChooseOne/SilentOtExtSender.cpp b/libOTe/TwoChooseOne/SilentOtExtSender.cpp index f8116daa..c4b8e007 100644 --- a/libOTe/TwoChooseOne/SilentOtExtSender.cpp +++ b/libOTe/TwoChooseOne/SilentOtExtSender.cpp @@ -1,16 +1,7 @@ #include "libOTe/TwoChooseOne/SilentOtExtSender.h" -#ifdef ENABLE_SILENTOT +#include "libOTe/Tools/LDPC/LdpcEncoder.h" -#include "libOTe/Tools/Tools.h" -#include "libOTe/TwoChooseOne/SilentOtExtReceiver.h" -#include -#include "cryptoTools/Common/Log.h" -#include "cryptoTools/Common/ThreadBarrier.h" -#include "libOTe/Base/BaseOT.h" -#include -#include -#include "libOTe/Tools/LDPC/LdpcSampler.h" -#include "libOTe/Vole/NoisyVoleReceiver.h" +#if defined(ENABLE_SILENTOT) || defined(ENABLE_SILENT_VOLE) namespace osuCrypto { @@ -39,6 +30,56 @@ namespace osuCrypto } + void SilverConfigure( + u64 numOTs, u64 secParam, + MultType mMultType, + u64& mRequestedNumOTs, + u64& mNumPartitions, + u64& mSizePer, + u64& mN2, + u64& mN, + u64& gap, + S1DiagRegRepEncoder& mEncoder) + { + mRequestedNumOTs = numOTs; + auto mScaler = 2; + + auto code = mMultType == MultType::slv11 ?

These protocol bootstraps all the other -OT extension protocols. Within the OT extension protocols, we have 1-out-of-2, -1-out-of-N and K-out-of-N, both in the semi-honest and malicious settings. See The `frontend` or `libOTe_Tests` folder for examples. - -All implementations are highly optimized using fast SSE instructions and vectorization -to obtain optimal performance both in the single and multi-threaded setting. See -the **Performance** section for a comparison between protocols and to other libraries. - -Networking can be performed using both the sockets provided by the library and -external socket classes. See the [networking tutorial](https://github.com/ladnir/cryptoTools/blob/57220fc45252d089a7fd90816144e447a2ce02b8/frontend_cryptoTools/Tutorials/Network.cpp#L264) for an example. - - -## Build - -The library is *cross platform* and has been tested on Windows, Mac and Linux. -There is one mandatory dependency on [Boost 1.75](http://www.boost.org/) (networking), -and three **optional dependencies** on [libsodium](https://doc.libsodium.org/), -[Relic](https://github.com/relic-toolkit/relic), or -[SimplestOT](https://github.com/osu-crypto/libOTe/tree/master/SimplestOT) (Unix only) -for Base OTs. -CMake 3.15+ is required and the build script assumes python 3. - -The library can be built as -``` -git clone --recursive https://github.com/osu-crypto/libOTe.git -cd libOTe -python build.py --boost --relic -D ENABLE_ALL_OT=ON -``` -The main executable with examples is `frontend` and is located in the build directory, eg `out/build/linux/frontend/frontend.exe, out/build/x64-Release/frontend/Release/frontend.exe` depending on the OS. - -### Build Options -LibOTe can be built with various only the selected protocols enabled. `-D ENABLE_ALL_OT=ON` will enable all available protocols depending on platform/dependancies. The `ON`/`OFF` options include - -**Malicious base OT:** - * `ENABLE_SIMPLESTOT` the SimplestOT [[CO15]](https://eprint.iacr.org/2015/267.pdf) protocol (relic or sodium). - * `ENABLE_SIMPLESTOT_ASM` the SimplestOT base OT protocol [[CO15]](https://eprint.iacr.org/2015/267.pdf) protocol (linux assembly). - * `ENABLE_MRR` the McQuoid Rosulek Roy [[MRR20]](https://eprint.iacr.org/2020/1043) protocol (relic or sodium). - * `ENABLE_MRR_TWIST` the McQuoid Rosulek Roy [[MRR21]](https://eprint.iacr.org/2021/682) protocol (sodium fork). - * `ENABLE_MR` the Masny Rindal [[MR19]](https://eprint.iacr.org/2019/706.pdf) protocol (relic or sodium). - * `ENABLE_MR_KYBER` the Masny Rindal [[MR19]](https://eprint.iacr.org/2019/706.pdf) protocol (Kyber fork). - * `ENABLE_NP` the Naor Pinkas [NP01] base OT (relic or sodium). - -**1-out-of-2 OT Extension:** - * `ENABLE_IKNP` the Ishai et al [[IKNP03]](https://www.iacr.org/archive/crypto2003/27290145/27290145.pdf) semi-honest protocol. - * `ENABLE_KOS` the Keller et al [[KOS15]](https://eprint.iacr.org/2015/546) malicious protocol. - * `ENABLE_DELTA_KOS` the Burra et al [[BLNNOOSS15]](https://eprint.iacr.org/2015/472.pdf),[[KOS15]](https://eprint.iacr.org/2015/546) malicious Delta-OT protocol. - * `ENABLE_SILENTOT` the Couteau et al [CRR21],[[BCGIKRS19]](https://eprint.iacr.org/2019/1159.pdf) semi-honest/malicious protocol. - * `ENABLE_SOFTSPOKEN_OT` the Roy [[Roy22]](https://eprint.iacr.org/2022/192) malicious/semi-honest protocols. - - **Vole:** - * `ENABLE_SILENT_VOLE` the Couteau et al [CRR21] semi-honest/malicious protocol. - - Addiition options can be set for cryptoTools. See the cmake output. - -### Dependancies - -Dependancies can be managed via the `build.py` script or installed via an external tool. If an external tool is used install to system location or set `-D CMAKE_PREFIX_PATH=path/to/install`. - -**Boost** -The library requires boost and can be fetched as -``` -python build.py --setup --boost -``` - -**Enabling/Disabling [Relic](https://github.com/relic-toolkit/relic) (for base OTs):** - The library can be built with Relic as -``` -python build.py --setup --relic -python build.py -D ENABLE_RELIC=ON -``` -Relic can be disabled by removing `--relic` from the setup and setting `-D ENABLE_RELIC=OFF`. - -**Enabling/Disabling [libsodium](https://github.com/osu-crypto/libsodium) (for base OTs):** - The library can be built with libsodium as -``` -python build.py --setup --sodium -python build.py -D ENABLE_SODIUM=ON -``` -libsodium can be disabled by removing `--sodium` from the setup and setting `-D ENABLE_SODIUM=OFF`. The McQuoid Rosulek Roy 2021 Base OTs uses a twisted curve which additionally require the `noclamp` option for Montgomery curves and is currently only in a [fork](https://github.com/osu-crypto/libsodium) of libsodium. If you prefer the stable libsodium, then install it and add `-D SODIUM_MONTGOMERY=OFF` as a cmake argument to libOTe. - -## Install - -libOTe can be installed and linked the same way as other cmake projects. By default the dependancies are not installed. To install all dependancies, run the following -``` -python build.py --setup --boost --relic --sodium --install -``` -You can also selectively install the dependancies. The install location can be specifying as `--install=path/to/installation`. Otherwise the system default is used. - -The main library is similarly installed as -``` -python build.py --install -``` - -By default, sudo is not used. If installation requires sudo access, then add `--sudo` to the `build.py` script arguments. See `python build.py --help` for full details. - - -## Linking -libOTe can be linked via cmake as -``` -find_package(libOTe REQUIRED) -target_link_libraries(myProject oc::libOTe) -``` -Other exposed targets are `oc::cryptoTools, oc::tests_cryptoTools, oc::libOTe_Tests`. In addition, cmake variables `libOTe_LIB, libOTe_INC, ENABLE_XXX` will be defined, where `XXX` is one of the libOTe options. - -To ensure that cmake can find libOTe, you can either install libOTe or build it locally and set `-D CMAKE_PREFIX_PATH=path/to/libOTe` or provide its location as a cmake `HINTS`, i.e. `find_package(libOTe HINTS path/to/libOTe)`. - - -## Example Code -A minimal working example showing how to perform `n` OTs using the IKNP protocol. -```cpp -void minimal() -{ - // Setup networking.

The `ON`/`OFF` options include + +**Malicious base OT:** + * `ENABLE_SIMPLESTOT` the SimplestOT [[CO15]](https://eprint.iacr.org/2015/267.pdf) protocol (relic or sodium). + * `ENABLE_SIMPLESTOT_ASM` the SimplestOT base OT protocol [[CO15]](https://eprint.iacr.org/2015/267.pdf) protocol (linux assembly). + * `ENABLE_MRR` the McQuoid Rosulek Roy [[MRR20]](https://eprint.iacr.org/2020/1043) protocol (relic or sodium). + * `ENABLE_MRR_TWIST` the McQuoid Rosulek Roy [[MRR21]](https://eprint.iacr.org/2021/682) protocol (sodium fork). + * `ENABLE_MR` the Masny Rindal [[MR19]](https://eprint.iacr.org/2019/706.pdf) protocol (relic or sodium). + * `ENABLE_MR_KYBER` the Masny Rindal [[MR19]](https://eprint.iacr.org/2019/706.pdf) protocol (Kyber fork). + * `ENABLE_NP` the Naor Pinkas [NP01] base OT (relic or sodium). + +**1-out-of-2 OT Extension:** + * `ENABLE_IKNP` the Ishai et al [[IKNP03]](https://www.iacr.org/archive/crypto2003/27290145/27290145.pdf) semi-honest protocol. + * `ENABLE_KOS` the Keller et al [[KOS15]](https://eprint.iacr.org/2015/546) malicious protocol. + * `ENABLE_DELTA_KOS` the Burra et al [[BLNNOOSS15]](https://eprint.iacr.org/2015/472.pdf),[[KOS15]](https://eprint.iacr.org/2015/546) malicious Delta-OT protocol. + * `ENABLE_SOFTSPOKEN_OT` the Roy [Roy22](https://eprint.iacr.org/2022/192) semi-honest/malicious protocol. + * `ENABLE_SILENTOT` the Couteau et al [CRR21],[[BCGIKRS19]](https://eprint.iacr.org/2019/1159.pdf) semi-honest/malicious protocol. + + **Vole:** + * `ENABLE_SILENT_VOLE` the Couteau et al [CRR21] semi-honest/malicious protocol. + + Addition options can be set for cryptoTools. See the cmake output. + +### Dependencies + +Dependencies can be managed by cmake/build.py or installed via an external tool. If an external tool is used install to system location or set `-D CMAKE_PREFIX_PATH=path/to/install`. By default `build.py` calls cmake with the command line argument +``` +-D FETCH_AUTO=true +``` +. This tells cmake to first look for dependencies on *the system* and if not found then it will be downloaded and built automatically. If set to `false` then the build will fail if not found. Each dependency can downloaded and build for you by explicitly setting it's `FETCH_***` variable to `true`. See blow. The python `build.py` script by default sets `FETCH_AUTO=true` and can be set to `false` by calling it with `--noauto`. + + +**Enabling/Disabling [Relic](https://github.com/relic-toolkit/relic) (for base OTs):** + The library can be built with Relic as +``` +python build.py --relic +``` +Relic can be disabled by removing `--relic` from the setup and setting `-D ENABLE_RELIC=OFF`. Relic can always be fetched and locally built using `-D FETCH_RELIC=true`. + +**Enabling/Disabling [libsodium](https://github.com/osu-crypto/libsodium) (for base OTs):** + The library can be built with libsodium as +``` +python build.py --sodium +``` +libsodium can be disabled by removing `--sodium` from the setup and setting `-D ENABLE_SODIUM=OFF`. Sodium can always be fetched and locally built using `-D FETCH_SODIUM=true`. + +The McQuoid Rosulek Roy 2021 Base OTs uses a twisted curve which additionally require the `noclamp` option for Montgomery curves and is currently only in a [fork](https://github.com/osu-crypto/libsodium) of libsodium. If you prefer the stable libsodium, then install it and add `-D SODIUM_MONTGOMERY=OFF` as a cmake argument to libOTe. + +## Install + +libOTe can be installed and linked the same way as other cmake projects. To install the library and all downloaded dependencies, run the following +``` +python build.py --install +``` + + +By default, sudo is not used. If installation requires sudo access, then add `--sudo` to the `build.py` script arguments. See `python build.py --help` for full details. + + +## Linking +libOTe can be linked via cmake as +``` +find_package(libOTe REQUIRED) +target_link_libraries(myProject oc::libOTe) +``` +Other exposed targets are `oc::cryptoTools, oc::tests_cryptoTools, oc::libOTe_Tests`. In addition, cmake variables `libOTe_LIB, libOTe_INC, ENABLE_XXX` will be defined, where `XXX` is one of the libOTe options. + +To ensure that cmake can find libOTe, you can either install libOTe or build it locally and set `-D CMAKE_PREFIX_PATH=path/to/libOTe` or provide its location as a cmake `HINTS`, i.e. `find_package(libOTe HINTS path/to/libOTe)`. + + + +## Help + +Contact Peter Rindal peterrindal@gmail.com for any assistance on building +or running the library. + +## Citing + + Spread the word! + +``` +@misc{libOTe, + author = {Peter Rindal, Lance Roy}, + title = {{libOTe: an efficient, portable, and easy to use Oblivious Transfer Library}}, + howpublished = {\url{https://github.com/osu-crypto/libOTe}}, +} +``` + +## Citation + +[NP01] - Moni Naor, Benny Pinkas, _Efficient Oblivious Transfer Protocols_. + +[IKNP03] - Yuval Ishai and Joe Kilian and Kobbi Nissim and Erez Petrank, _Extending Oblivious Transfers Efficiently_. + +[KOS15] - Marcel Keller and Emmanuela Orsini and Peter Scholl, _Actively Secure OT Extension with Optimal Overhead_.
