Dynamic Remote Attestation Based on Concerns

Based on the analysis relationships of challenger and attestation in remote attestation process, we propose a dynamic remote attestation model based on concerns. By combines the trusted root and application of dynamic credible monitoring module, Convert the Measurement for all load module of integrity measurement architecture into the Attestation of the basic computing environments, dynamic credible monitoring module, and request service software module. Discuss the rationality of the model. The model used Merkel hash tree to storage applications software integrity metrics, both to protect the privacy of the other party application software, and also improves the efficiency of remote attestation. Experimental prototype system shows that the model can verify the dynamic behavior of the software, to make up for the lack of static measure.
