A plausible approach to computer-aided cryptographic proofs
Authors: Shai HaleviAbstract:
This paper tries to sell a potential approach to making the process of writing and verifying our cryptographic proofs less prone to errors. Specifically, I advocate creating an automated tool to help us with the mundane parts of writing and checking common arguments in our proofs. On a high level, this tool should help us verify that two pieces of code induce the same probability distribution on some of their common variables.
In this paper I explain why I think that such a tool would be useful, by considering two very different proofs of security from the literature and showing the places in those proofs where having this tool would have been useful. I also explain how I believe that this tool can be built. Perhaps surprisingly, it seems to me that the functionality of such tool can be implemented using only ``static code analysis’’ (i.e., things that compilers do).
