AES_TAG is Leaked

[jmp0x7c00]

the variable AES_TAG is security-critical, but it is written into an untrusted file by plaintext:

BiORAM-SGX/dataowner_data/EncryptAES_SGX/Enclave/Enclave.cpp

Line 188 in d86dab2

status = OCALL_SaveFile(MAC_filename.c_str(), MAC_filename.length() + 1, AES_TAG, 16);

An attacker can open the file to get the AES_TAG easily.
