Blockchains have motivated a surge of research and development into succinct probabilistic proofs. As proof constructions have gotten dramatically more efficient, entirely new applications have become feasible in other areas as well. This talk will discuss two proposed applications in the area of network security. First, zero-knowledge middleboxes (ZKMBs), which enable network users to prove that their packets comply with a network usage policy (e.g. a domain blocklist) without revealing their actual data to the middlebox. Second, replacing certificate authorities (CAs) with proofs in a new protocol called DOVE, removing the massive trust placed in the current CA ecosystem.
