Paralocks: Role-Based Information Flow Control and Beyond

Abstract

In this talk we present Paralocks, a language for building expressive but statically verifiable fine-grained information flow policies. Paralocks combine the expressive power of Flow Locks (Broberg & Sands, ESOP'06) with the ability to express policies involving run-time principles, roles (in the style of role-based access control), and relations (such as ``acts-for'' in discretionary access control). We illustrate the Paralocks policy language by giving a simple encoding of Myers and Liskov's Decentralized Label Model (DLM). Furthermore -- and unlike the DLM -- we provide an information flow semantics for full Paralock policies. Finally we sketch how Paralocks can be statically verified by providing a simple programming language incorporating Paralock policy specifications, and a static type system which soundly enforces information flow security according to the Paralock semantics.
