Abstract

We consider a sequential object-oriented language with pointers and mutable state, private fields and class-based visibility, dynamic binding and inheritance, recursive classes, casts and type tests, and recursive methods. Programs are annotated with security levels, constrainedby security typing rules. A noninterference theorem shows how the rules ensure pointer confinement and secure information flow.
