Remote Attestation With Domain-Based Integrity Model and Policy Analysis

The authors propose and implement an innovative remote attestation framework called DR@FT for efficiently measuring a target system based on an information flow-based integrity model. With this model, the high integrity processes of a system are first measured and verified, and these processes are then protected from accesses initiated by low integrity processes. Toward dynamic systems with frequently changed system states, their framework verifies the latest state changes of a target system instead of considering the entire system information. Their attestation evaluation adopts a graph-based method to represent integrity violations, and the graph-based policy analysis is further augmented with a ranked violation graph to support high semantic reasoning of attestation results.
