To program parallel systems efficiently and easily, a wide range of programming models
have been proposed, each with different choices concerning synchronization and …

Actors have become widespread in programming languages and programming frameworks
focused on parallel and distributed computing. While actors provide a more disciplined …

This paper presents a method for detecting cyber-attacks in cyber-physical systems using a
monitor. The method employs an abstract model called Tiny Twin, which is built at design …

Abstract Models are central to engineering. They are used for analysis, synthesis, and
communication between humans. A given artifact or process may have multiple models with …

We propose CRYSTAL framework for automated cybersecurity assurance of cyber-physical
systems (CPS) at design-time and runtime. We build attack models and apply formal …

The value of verification of cyberphysical systems depends on the relationship between the
state of the software and the state of the physical system. This relationship can be complex …

Programming time-critical systems is notoriously difficult. In this paper we propose an actor-
oriented programming model with a semantic notion of time and a deterministic coordination …

Model checking a software system is about verifying that the state trajectory of every
execution of the software satisfies formally specified properties. The set of possible …

Actor model is a concurrent object-based computational model in which actors are the units
of concurrency and communicate via asynchronous message passing. Timed Rebeca is an …

In this work, we present an actor-based approach for security analysis of Cyber-Physical
Systems at the design phase. We use Timed Rebeca, an actor-based modeling language, to …
