NettetIntel Protected File System Library. Intel Protected File System Library provides protected files API for Intel SGX enclaves. With this API, the files are encrypted and saved on the untrusted disk during a write operation, and they are verified for confidentiality and integrity during a read operation. NettetIntel SGX introduced a feature called Intel Protection File System Library (IPFS) to create, operate and delete files inside the enclave. WAMR supports the mapping of IPFS on WASI functions related to file interactions, providing seamless persistence with confidentiality and integrity to the hosted WebAssembly applications in the enclave.

Intel Protected FS
NettetIntel SGX is a hardware-based TEE technology. It introduces new platform extensions such as a Memory Encryption Engine (MEE) and new CPU instructions ( SGX1 and SGX2 [ 26, 42 ]) to enable applications to create private memory regions protected from privileged software. NettetDiskShield uses Intel SGX to provide Trusted Execution Environment (TEE) to the host, implements the file system into SSD firmware that provides a Trusted Computing Base (TCB), and uses a two-way authentication mechanism to securely transfer data from the host TEE to the SSD TCB against data tampering attacks.

Isolated execution of an enclave process restricts access to a subset of memory such that only that particular enclave can access it. Entry points defined in trusted code are called ECALL. midnight velvet promotional codes
