Fault Tolerance & Testable Software Security: A Method of Quantifiable Non-Malleability with Respect to Time

In this paper, we demonstrate there exists practical limits to the recoverability and integrity verification (non-malleability) of software with respect to time a property to the best of our knowledge not demonstrated previously; this in turn, implies practical limits to software security using current existing processing hardware. Non-malleability applied to software implies that it should be infeasible for an attacker to modify a piece of software, thus creating a software fault. Given the recoverability limitation, we demonstrate a quantifiable definition for secure software with respect to integrity/tamper resistance.
