Gradual Information Flow Typing

Abstract

We present a method to support the gradual evolution of secure scripts by formalizing an extension of the simply-typed lambda calculus that provides information flow constructs. These constructs allow initially insecure programs to evolve via targeted refactoring and to provide dynamic information flow guarantees via casts, as well as static information flow guarantees via labeled types.
