State based ownership, reentrance, and encapsulation
- In: European Conference on Object-Oriented Programming (ECOOP
"... Abstract. A properly encapsulated data representation can be revised for refactoring or other purposes without affecting the correctness of client programs and extensions of a class. But encapsulation is difficult to achieve in object-oriented programs owing to heap based structures and reentrant ca ..."

Abstract. A properly encapsulated data representation can be revised for refactoring or other purposes without affecting the correctness of client programs and extensions of a class. But encapsulation is difficult to achieve in object-oriented programs owing to heap based structures and reentrant callbacks. This paper shows that it is achieved by a discipline using assertions and auxiliary fields to manage invariants and transferrable ownership. The main result is representation independence: a rule for modular proof of equivalence of class implementations. 1
Verifying a secure information flow analyzer
- In TPHOLS
, 2005
"... Abstract. Denotational semantics for a substantial fragment of Java is formalized by deep embedding in PVS, making extensive use of dependent types. A static analyzer for secure information flow for this language is proved correct, that is, it enforces noninterference. 1 ..."
