Abstract(in English) | Intel SGX is a kind of TEE (Trusted Execution Environment) and can protect the confidentiality and integrity of programs and data in the memory of SGX from attacks involving privileged instructions from the OS, hypervisor, etc. SGX offers Remote Attestation (RA), which confirms the authenticity of the genuine platform and intended software on SGX (i.e., TA: Trusted Application).In recent years, SGX is utilized for the clouds, SGX RA is also developed for Cloud in 2018; the Elliptic Curve Digital Signature Algorithm (ECDSA) Attestation, which is intended for use in data centers. However, the degree of freedom of implementation is higher than in the past, and it is unclear who guarantees the verification results. This paper describes the provisioning and execution of the current ECDSA Attestation and clarifies who guarantees the verified elements. Furthermore, from this, the challenges of ECDSA Attestation will be identified, and then measures for improvement will be discussed. |
