Remote attestation for trustworthiness of computing platform is a focus research work in Trusted Computing,but there exist some problems in some of today's attestation approaches.System Behavior based Trustworthiness Attestation Model(BTAM) is a trustworthiness attestation model based on system behavior of attesting computing platform in trusted computing environment.BTAM determines the trustworthiness of attesting platform by its behavior sequences against the platform behavior expectation policy,therefore it avoids the difficulties in describing the state of attesting platform,assures the feasibility and scalability in the model implementation.The prototype implementation of BTAM proves the capability of BTAM in defending malicious code such as Trojan and virus and eliminating security policy conflicted activities,and the run-time performance analysis also shows the high efficiency of BTAM in security.
