请问一下,mesatee是怎么进行sgx的合法性验证的?

$ export AS_SPID="00000000000000000000000000000000" # SPID from IAS subscription
$ export AS_KEY="00000000000000000000000000000000" # Primary key/Secondary key from IAS subscription
$ export AS_ALGO="sgx_epid" # Attestation algorithm, sgx_epid for IAS
$ export AS_URL="https://api.trustedservices.intel.com:443" # IAS URL
这些参数是什么含义?

sgx合法性认证可以必须通过intel官网进行认证吗?

可以离线认证吗?

谢谢

  • SPID, KEY 是给 Intel Attestation Service [1] 使用的。
  • 除了用 Intel Attestation Service,也可以用 DCAP [2] 搭建 offline 的 attestation。
