Of course the enclave could be simplified considerably since now it has full code for EINITTOKEN generation, which is probably an overkill for a selftest. It could be simple as just enter and return to and from enclave or something in-between in terms of complexity. Even for the simplest enclave you need a signing tool (see sgxsign.c in my sgx-le repository), a custom linker script and a sophisticated makefile. /Jarkko
