Intel SGX

Hi,

I'm trying to create a basic sgx via visual studio 2015 on my windows 10 computer.
However, every time I call sgx_create_enclave the metadata is invalid and it returns with the status SGX_ERROR_INVALID_METADATA (0X2009). 
From what I understand this means the Enclave.signed.dll is corrupt, but I don't understand how I can fix it.

Thanks in advance

Hello,

I checked the uploaded Intel SGX sample application(simulation mode) source.

1) In simulation mode, the application and enclave configurations should point "Local Windows Debugger" .
2) Moreover I found that below said path in enclave project setting is pointing to "$ProjectDir" instead of "$OutDir"
"Configuration Properties --> Debugging --> Working Directory"

Please make sure that the latest Intel SGX SDK(1.7) is used with Visual Studio 2015 and Windows 10.

Thanks,
R.Prabu

The document Software Guard Extensions programming Reference  is written "extensions allow an application to instantiate a protected container, referred to as an enclave. An enclave is a protected area in the application’s address space (see Figure 1-1), which provides confidentiality and integrity even in the presence of privileged malware "
However, figure 1 does not reflect what is written in the text above. What really happens with the enclave? It sits within the memory space of the application, or it sits in a separate memory space of the application in main memory?sgxx_0.jpg
