Dec 2, 2019 · In the process-based TEE model, a process that needs to run securely is divided into two components: trusted (assumed to be secure) and untrusted (assumed to be insecure). An enclave has the CPU package boundary as its security perimeter and provides confidentiality and integrity Intel Software Guard Extensions ( SGX) is a set of instruction codes implementing trusted execution environment that are built into some Intel central processing units (CPUs). Applications designed for SGX enclaves split the application into two parts: an untrusted “host” and a trusted “enclave” which run inside a TEE. Unfortunately, existing TEE solutions suffer from significant design Verify the enclave meets current TCB requirements; Evaluates the enclave evidence against a policy defining the expected enclave owner (mrsigner) and code integrity (mrenclave) The attestation evidence for each of microservice is stored in a blockchain-backed ledger and referenced using a unique ID in every attestation token generated. However, both LIGHT-ENCLAVE and Nested Enclave require hardware modifications, making it challenging to apply them to commercial CPUs. e. In this paper, we describe the implemen-tation SEV-ES), enhancing enclave applications’ inter-TEE op-erability in a virtualized environment.
