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.
