The long-term vision of this project is one of "vehicles that do not crash." About 35,000 lives are lost every year due to road accidents in the US. In intersections alone, there are about 8,500 fatalities. More than a million accidents and injuries per year take a major toll on productivity. Most accidents occur due to human errors such as distractions, tiredness or other forms of impairment. Traffic delays cause driving commuters to spend an aggregate week stuck in traffic every year, leading to huge losses in productivity.

CMU Lablet: SOSL

Science of Security Lablet:
Security Reasoning for Distributed Systems with Uncertainties

The broad goal of the Science of Security Lablet (SOSL) is to identify scientific principles that can lead to approaches to the development, evaluation, and evolution of secure systems at scale. The focus on scalability derives from a recognition that modern software-intensive systems have more components and a greater diversity of suppliers. The theme of scalability includes two principal areas of focus, which are composability and usability.


Logical Foundations of Cyber-Physical Systems (LFCPS)
Principal Investigators André Platzer (CMU)
Support NSF CNS-1054246

This project develops logical foundations for cyber-physical systems (CPS), i.e., systems that combine cyber aspects such as communication and computer control with physical aspects such as movement in space. CPS applications abound. Ensuring their correct functioning, however, is a serious challenge. Scientists and engineers need analytic tools to understand and predict the behavior of their systems. That's the key to designing smart and reliable control. By providing such analytic foundations, this project addresses an intellectual grand challenge that has substantial scientific, economical, societal, and educational impact arising from the benefits of improved CPS analysis and design. In order to tame their complexity, this project studies CPS as multi-dynamical systems, i.e., in terms of the elementary dynamical aspects of their parts.

Automatic Verification and Analysis of Complex Systems (AVACS)

André Platzer has been a research assistant in the Correct System Design group of Prof. Ernst-Rüdiger Olderog at the University of Oldenburg, Germany. André's research ambitions on hybrid and real-time systems are connected with the Transregional Collaborative Research Center SFB/TR AVACS, which is led by Director Prof. Werner Damm. The project AVACS (Automatic Verification and Analysis of Complex Systems) is a collaborative research project of the Universities of Freiburg, Oldenburg, and Saarbrücken, and the Max-Planck Institute für Informatik in Saarbrücken. It addresses the rigorous mathematical analysis of models of complex safety critical computerized systems, such as aircrafts, trains, cars, or other artifacts, whose failure can endanger human life. The aim is to raise the state of the art in automatic verification and analysis techniques from its current level, where it is applicable only to isolated facets (concurrency, time, continuous control, stability, dependability, mobility, data structures, hardware constraints, modularity, levels of refinement), to a level allowing a comprehensive and holistic verification of such systems. In this project, André Platzer primarily focused on logic-based verification of hybrid systems.


The KeY Project: Integrated Deductive Software Design

The minor thesis and diploma thesis of André Platzer have been supervised by Prof. Peter Schmitt and Prof. Bernhard Beckert in the context of the KeY project. The goal of the KeY project is to develop a comprehensive tool supporting formal specification and verification of object-oriented Java Card programs within a commercial platform for UML/JML-based software development. This approach is based on the design-by-contract paradigm. In KeY, contracts are verified statically using a semi-automatic, interactive theorem prover on the basis of a dynamic logic. André Platzer developed a sound and relatively complete calculus for object-oriented program verification. He also worked on logic-based specification-extraction, with which logical specifications can be synthesized from object-oriented programs.
