Method and Apparatus to provide secure application execution
An instruction of software outside of a secure enclave is decoded and the decoded instruction is executed to read bytes from an enclave page cache (EPC) page of an enclave. The enclave is marked as being a debug enclave. An address of the bytes to read from the debug enclave is preferably provided i...

| description | An instruction of software outside of a secure enclave is decoded and the decoded instruction is executed to read bytes from an enclave page cache (EPC) page of an enclave. The enclave is marked as being a debug enclave. An address of the bytes to read from the debug enclave is preferably provided in our CX. A debug bit is preferably set in the EPC to indicate that the enclave is a debug enclave. The contents of the debug enclave are preferably encrypted. The debug enclave may allow access using commands EDBGRD (read) and EDBGWR (write). |
