+# BLS threshold signature
+
+An implementation of BLS threshold signature
+
+# Installation Requirements
+
+Create a working directory (e.g., work) and clone the following repositories.
+```
+mkdir work
+cd work
+git clone git://github.com/herumi/mcl.git
+git clone git://github.com/herumi/bls.git
+git clone git://github.com/herumi/cybozulib_ext ; for only Windows
+```
+
+# **REMARK** libbls.a for C++ interface(bls/bls.hpp) is removed
+Link `lib/libbls256.a` or `lib/libbls384.a` to use `bls/bls.hpp` according to MCLBN_FP_UNIT_SIZE = 4 or 6.
+
+# Build and test for Linux
+To make and test, run
+```
+cd bls
+make test
+```
+To make sample programs, run
+```
+make sample_test
+```
+
+# Build and test for Windows
+1) make static library and use it
+```
+mklib
+mk -s test\bls_c384_test.cpp
+bin\bls_c384_test.exe
+```
+
+2) make dynamic library and use it
+```
+mklib dll
+mk -d test\bls_c384_test.cpp

+```

+# Library
+* libbls256.a/libbls256_dy.so ; for BN254 compiled with MCLBN_FP_UNIT_SIZE=4
+* libbls384.a/libbls384_dy.so ; for BN254/BN381_1/BLS12_381 compiled with MCLBN_FP_UNIT_SIZE=6

+
+# API
+
+## Basic API
+
+BLS signature
+```
+e : G2 x G1 -> Fp12 ; optimal ate pairing over BN curve
+Q in G2 ; fixed global parameter
+H : {str} -> G1
+s in Fr: secret key
+sQ in G2; public key
+s H(m) in G1; signature of m
+verify ; e(sQ, H(m)) = e(Q, s H(m))
+```
+
+```
+void bls::init();
+```
+
+Initialize this library. Call this once to use the other api.
+
+```
+void SecretKey::init();
+```
+
+Initialize the instance of SecretKey. `s` is a random number.
+
+```
+void SecretKey::getPublicKey(PublicKey& pub) const;
+```
+
+Get public key `sQ` for the secret key `s`.
+
+```
+void SecretKey::sign(Sign& sign, const std::string& m) const;
+```
+
+Make sign `s H(m)` from message m.
+
+```
+bool Sign::verify(const PublicKey& pub, const std::string& m) const;
+```
+
+Verify sign with pub and m and return true if it is valid.
+
+```
+e(sQ, H(m)) == e(Q, s H(m))
+```
+
+### Secret Sharing API
+
+```
+void SecretKey::getMasterSecretKey(SecretKeyVec& msk, size_t k) const;
+```
+
+Prepare k-out-of-n secret sharing for the secret key.
+`msk[0]` is the original secret key `s` and `msk[i]` for i > 0 are random secret key.
+
+```
+void SecretKey::set(const SecretKeyVec& msk, const Id& id);
+```
+
+Make secret key f(id) from msk and id where f(x) = msk[0] + msk[1] x + ... + msk[k-1] x^{k-1}.
+
+You can make a public key `f(id)Q` from each secret key f(id) for id != 0 and sign a message.
+
+```
+void Sign::recover(const SignVec& signVec, const IdVec& idVec);
+```
+
+Collect k pair of sign `f(id) H(m)` and `id` for a message m and recover the original signature `s H(m)` for the secret key `s`.
+
+### PoP (Proof of Possesion)
+
+```
+void SecretKey::getPop(Sign& pop) const;
+```
+
+Sign pub and make a pop `s H(sQ)`
+
+```
+bool Sign::verify(const PublicKey& pub) const;
+```
+
+Verify a public key by pop.
+
+# Check the order of a point
+
+deserializer functions check whether a point has correct order and
+the cost is heavy for especially G2.
+If you do not want to check it, then call
+```
+void blsSignatureVerifyOrder(false);
+void blsPublicKeyVerifyOrder(false);
+```
+
+cf. subgroup attack
+
+# Go
+```
+make test_go
+```
+
+# WASM(WebAssembly)
+```
+mkdir ../bls-wasm
+make bls-wasm
