Better Prefix Authentication

Published 29 Aug 2023 in cs.CR and cs.DS | (2308.15058v1)

Abstract: We present new schemes for solving prefix authentication and secure relative timestamping. By casting a new light on antimonotone linking schemes, we improve upon the state of the art in prefix authentication, and in timestamping with rounds of bounded length. Our designs can serve as more efficient alternatives to certificate transparency logs.
