Title:
CryptoZoo: A Viewer for Reduction Proofs
Authors: Chris Brzuska, Christoph Egger, Kirthivaasan Puniamurthy
Abstract:Cryptographers rely on visualization to effectively communicate cryptographic constructions with one another. Visual frameworks such as constructive cryptography (TOSCA 2011), the joy of cryptography (online book) and state-separating proofs (SSPs, Asiacrypt 2018) are useful to communicate not only the construction, but also their proof visually by representing a cryptographic system as graphs.
One SSP core feature is the re-use of code, e.g., a package of code might be used in a game and be part of the description of a reduction as well. Thus, in a proof, the linear structure of a paper either requires the reader to turn pages to find definitions or writers to re-state them, thereby interrupting the visual flow of the game hops that are defined by a sequence of graphs.
We present an interactive proof viewer for state-separating proofs (SSPs) which addresses the limitations and perform three case studies: The equivalence between simulation-based and game-based notions for symmetric encryption, the security proof of the Goldreich-Goldwasser-Micali construction of a pseudorandom function from a pseudorandom generator, and Brzuska’s and Oechsner’s SSP formalization of the proof for Yao’s garbling scheme.
