Verifying WAVE proofs using Intel SGX

This code is adapted from the Intel Remote Attestation Sample Code and includes a WAVE proof verification library as a submodule. To use this project, make sure to have the prerequisites installed as specified in the first link.

Other Notes

  • The file utils/settings.h contains options for the client and enclave/app
  • I have changed the build such that the client and enclave/app are built separately

Using this Library

First, clone the repository into the appropriate directory in your Go source tree (src/github.com/ddreyer/wave-verify-sgx) and then build the library as described below. This library can be used as an imported package via import "github.com/ddreyer/wave-verify-sgx/lang/go". A Go testing suite can be run via the command go test in the lang/go directory. The testing suite requires that the WAVE daemon be running. WAVE releases can be found here

Building the Enclave library

  • These three paths need to be in your LD_LIBRARY_PATH environment variable:
    • /opt/openssl/1.1.0i/lib
    • $GOPATH/src/github.com/ddreyer/wave-verify-sgx/enclave_plus_app_src
    • Path to Intel SGX Linux libraries ($PREFIX/linux-sgx/linux/installer/bin/sgxsdk/sdk_libs)
  $ cd enclave_plus_app_src
  $ ./bootstrap
  $ ./configure --with-openssldir=/opt/openssl/1.1.0i
  $ make
  $ ./run-enclave-app
  $ g++ -shared *.o ../utils/*.o -L/home/sgx/linux-sgx/linux/installer/bin/sgxsdk/lib64 -L/opt/openssl/1.1.0i/lib -L/opt/intel/sgxssl/lib64   -lsgx_urts -lsgx_ukey_exchange -lsgx_uae_service -lcrypto -l:libsgx_capable.a -lpthread -ldl -lsgx_usgxssl -o libverify.so

Building and Running the Client

$ cd client_src
$ ./bootstrap
$ ./configure --with-openssldir=/opt/openssl/1.1.0i
$ make
$ ./run-client
