Abstract:

Most tools for reasoning about programs start with abstract syntax trees (ASTs), but many flaws we find in systems arise within concrete syntax (c.f., SQL injection attacks). In this talk, I will describe some on-going work using Coq to construct efficient, provably correct parsers from regular grammars. The approach is based on a generalization of the algebraic techniques of Brzozowski, and leads to an elegant theory that is surprisingly tricky to formalize.

Biography:
