Dynamic Logic with Parallel Operator for Verifying Communication Protocols

In this paper, we present a dynamic logic with parallel operators for the formal verification of authenticity and safety properties of cryptographic protocols. The logic incorporates communication actions and is specifically designed to reason about protocol executions in adversarial environments. We extend an existing dynamic logic with parallel operators by introducing concepts derived from the Dolev-Yao intruder model. As the underlying logic is completely axiomatizable, we obtain a complete axiomatization for the extended system. Furthermore, we develop a tableau calculus for the proposed logic and prove its termination, soundness, and completeness.

CCS-Based Dynamic Logics for Communicating Concurrent Programs

This work presents three increasingly expressive Dynamic Logics in which the programs are CCS processes (sCCS-PDL, CCS-PDL and XCCS-PDL). Their goal is to reason about properties of concurrent programs and systems described using CCS. In order to accomplish that, CCS's operators and constructions are added to a basic modal logic in order to create dynamic logics that are suitable for the description and verification of properties of communicating, concurrent and non-deterministic programs and systems, in a similar way as PDL is used for the sequential case. We provide complete axiomatizations for the three logics. Unlike Peleg's Concurrent PDL with Channels, our logics have a simple Kripke semantics, complete axiomatizations and the finite model property.
