An Exploratory Study of Attestation Mechanisms for Trusted Execution Environments (2204.06790v2)
Published 14 Apr 2022 in cs.CR and cs.DC
Abstract: Attestation is a fundamental building block to establish trust over software systems. When used in conjunction with trusted execution environments, it guarantees that genuine code is executed even when facing strong attackers, paving the way for adoption in several sensitive application domains. This paper reviews existing remote attestation principles and compares the functionalities of current trusted execution environments as Intel SGX, Arm TrustZone and AMD SEV, as well as emerging RISC-V solutions.
