"A cyber process in a distributed system can fabricate its internal state in its communications with its peers. These state fabrications can cause other processes in the distributed system to make incorrect control decisions. Cyber-physical systems have a unique advantage in the detection of falsified states because processes typically have observable effects on a shared physical infrastructure. This physical infrastructure acts as a high-integrity message channel that broadcasts changes in individual process states. The objective of this research is to demonstrate that there are cases where physical feedback from the shared infrastructure can be used to detect state fabrications. To that end, this work introduces a distributed security mechanism called physical attestation that detects state fabrications in the future smart grid. Graph theory is used to prove that physical attestation works in general smart grid topologies, and the theory is supported with experimental results obtained from a smart grid test bed"--Abstract, page iii.
