问题 How to prove that certain data is calculated(or generated) inside Enclave(Intel SGX)? I tried to generate asymmetric key pair inside enclave(private key might be invisible to outside), and then expose public key with evidence(i guess quote or remote attestation related things). I got how remote attestation goes but, i cannot come up with applying remote attestation to verifying enclave-generated data. Is this possible scenario with Intel SGX? 回答1: You can prove the origin of the public key by

问题 I'm trying to write a simple SGX project for a start. So I have this main host application routine that I've pretty much copied from Lars Richter's blog: #define ENCLAVE_FILE _T("Enclave.signed.dll") #include <tchar.h> #include <cstdio> #include "sgx_urts.h" #include "Enclave_u.h" int main() { sgx_enclave_id_t eid; sgx_status_t ret = SGX_SUCCESS; sgx_launch_token_t token = { 0 }; int updated = 0; ret = sgx_create_enclave(ENCLAVE_FILE, SGX_DEBUG_FLAG, &token, &updated, &eid, NULL); if (ret !=

问题 I have a C++ struct like this: struct node { string splitOn; string label; bool isLeaf; vector<string> childrenValues; vector<node*> children; }; I wanted to pass or read this from App to the Intel SGX enclave. Based on what is mentioned here: https://software.intel.com/en-us/forums/intel-software-guard-extensions-intel-sgx/topic/703489 I tried this: APP: node *root = new node; root = buildDecisionTree(dataTable, root, *tableInfo); //this initializes the root void *data3 = static_cast<void*>

问题 I'm trying to write a simple SGX enclave that takes in a vector of booleans, but apparently edger8r creates c code; so the edl code enclave{ from "sgx_tstdc.edl" import *; include "BetaDist.h" include <vector> trusted { BetaDist Estimate(std::vector<bool> X, double max_z, double max_delta); }; untrusted { }; }; produces a compile error (Amusingly, the Intel compiler reports it under the title "catastrophic error") saying header vector can't be found. It seems to me that the problem can be

It seems to me that the problem can be solved just by compiling the output edge code with a c++ flag. Would that work? Even if so, is there a
