Preserving integrity of applications being executed in remote machines is an open problem. Integrity requires that application code is not tampered with, prior to or during execution, by a rogue user or a malicious software agent. This paper presents a methodology to enforce runtime integrity of application code by means of an integrity- preserving software component that is combined with the application. The software component is a trusted logic that can be replaced continuously from a remote location during run-time. For added assurance, the software component produces continuous sequence of proofs of its proper operation that are verified remotely.
