Abstract:This paper proposes a new proof-based approach to safe evolution of distributed software systems. Specifically, it extends the simple certification mechanism of proof-carrying code (PCC) to make it interactive and probabilistic, thereby devising interactive proof-carrying code (iPCC). With iPCC, a code consumer is convinced, with overwhelming probability, of the existence and validity of a safety proof of a transmitted code through interaction with a code producer. The iPCC mechanism theoretically solves the p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
