Compositional Methods for Information-Hiding
Protocols for information-hiding often use randomized primitives to obfuscate the link between the observables and the information to be protected. The degree of protection provide...

Structural Operational Semantics for Stochastic Process Calculi
Abstract. A syntactic framework called SGSOS, for defining well-behaved Markovian stochastic transition systems, is introduced by analogy to the GSOS congruence format for nondeter...

What Else Is Decidable about Integer Arrays?
We introduce a new decidable logic for reasoning about infinite arrays of integers. The logic is in the first-order fragment and allows (1) Presburger constraints on existentially...

Stochastic Games with Lossy Channels
We consider turn-based stochastic games on infinite graphs induced by game probabilistic lossy channel systems (GPLCS), the game version of probabilistic lossy channel systems (PLC...

Optimal Lower Bounds on Regular Expression Size Using Communication Complexity
The problem of converting deterministic finite automata into (short) regular expressions is considered. It is known that the required expression size is 2(n) in the worst case for ...

A Modal Deconstruction of Access Control Logics
We present a translation from a logic of access control with a "says" operator to the classical modal logic S4. We prove that the translation is sound and complete. We al...

Footprints in Local Reasoning
Local reasoning about programs exploits the natural local behaviour common in programs by focussing on the footprint - that part of the resource accessed by the program. We address...
