Password-authenticated Decentralized Identities

Code

• lib/ contains main PDID procedures including the implementation of modified OPAQUE and HMQV protocols
• lib/ecc.{c,h} are from Easy-ECC. It is modified (to be compatible with Intel SGX and its SDK) and extended by PDID-related functions (prefixed with pdid_)
• lib/tweetnacl.{c,h} are from TweetNaCl
• chaincode/ is the GPM smart contract to be deployed with Hyperledger Fabric Private Chaincode (FPC)

Local tests

Local (emulation) test should work out of box: make && ./local_test For better performance, you can use NaCl instead of TweetNaCl. Install NaCl, change the build path to yours export NACL_PATH=../../nacl-20110221/build/Latitude5280 and compile with the following flags (for x86_64) -I${NACL_PATH}/include/amd64 -L${NACL_PATH}/lib/amd64 -lnacl -DWITH_NACL

The integration test requires FPC deployment.

Hyperledger deployment

• Generate ./integration_test by make
• Install FPC as described here (version v1.0.0-rc3 branch.)

export GOPATH=~/
export FPC_PATH=$GOPATH/src/github.com/hyperledger/fabric-private-chaincode
git clone --recursive https://github.com/hyperledger/fabric-private-chaincode.git $FPC_PATH
cd $FPC_PATH/utils/docker
make pull-dev  // download image
make run-dev // enter container
cd $FPC_PATH
make // Build Fabric Private Chaincode

• Delete original chaincode/ in the container
• Copy chaincode/ and lib/ to FPC's samples/ (i.e., in the container). Then (in the container) cd samples/chaincode && make clean && make.
• In another terminal, run ./integration_test and follow its instructions (do not directly run ./test.sh in samples/chaincode after the above step. Some parameter should be defined via ./integration_test)
