Testing can demonstrate the presence of bugs, but never their absence. We explore how interactive theorem provers deliver mathematical certainty that an avionics microkernel is 100% bug-free.
By formulating machine-checked mathematical proofs linking the abstract specification to the actual C/SPARK Ada implementation, we prove that the kernel enforces confidentiality, integrity, and temporal isolation under all possible execution states.
Automated proof checkers verify millions of state transitions in seconds, freeing aerospace systems engineers to focus on architectural safety rather than hunting elusive memory corruption vulnerabilities.
