Real-Time Remote Attestation with Privacy Protection

How to ensure the freshness of measurement and protect the concrete system configuration from leaking are two major challenges faced by existing remote attestation solutions. This paper proposes a new attestation architecture, called RTRA, to resolve these problems. In RTRA the real-time state of the attester is collected and reported. And the privacy about the attester's binary configuration is protected through extending traditional property-based remote attestation architecture. Compared with existing property attestation architecture, RTRA is more scalable and secure since a unique proxy who is trusted totally to protect the whole configuration from leaking is not needed anymore.
