Nettet15. jan. 2024 · Intel Software Guard Extensions (SGX) is an extension to x86 architecture that enables user-level code to create trusted memory regions, called enclaves. However, the security provided by enclaves is not free: one primary performance overhead is enclave switches, which are expensive and can be triggered frequently by cross … NettetIn recent years, trusted execution environments (TEEs) such as Intel Software Guard Extensions (SGX) have gained a lot of attention in the database community. This is because TEEs provide an interesting platform for building trusted databases in the cloud. However, until recently SGX was only available on low-end single socket servers built …

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.

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. 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.
