Abstract

The time has arrived for truly trustworthy systems, backed by machine-checked proofs of security and reliability. Research demonstrates that formal whole-system analysis that applies to the C and binary implementation level is feasible, including proofs of integrity, authority confinement, confidentiality, and worst-case execution time. Because these proofs build on previous results, they become easier each year. However, they do have some limitations.
