There is a few information related to sealing, even no detailed explanation in the paper: Intel SGX explaned. All in this post are from Intel, with a little thought of mine. Sealing # Sealing is a service that Intel provides with Intel SGX technology for secure data saving. Intel SGX provides protections data only if it is in the enclave, part of main memory. Therefore, when the enclave process exits, the enclave will be destroyed and any data that is secured whithin the enclave will be lost.
