Abstract

This work presents a general and complete method to protect a system against possible malicious programs. We provide concepts for building a system that can automatically recover from an arbitrary state including even one in which a Byzantine execution of one or more programs repeatedly attempts to corrupt the system state. Preservation of a guest execution is guaranteed as long as the guest respects a predefined contract, while efficiency is improved by using stabilizing reputation. We augment a provable self-stabilizing host operating system implementation with a contract-enforcement framework example.
