“…UPPAAL is a formal model checking integration tool environment [13], which can be used for the development and verification of software and hardware systems, and has also been used for security reasoning [14,15]. UPPAAL was developed by the Department of Information Technology of the University of Uppsala, Sweden, and the Department of Computer Science of the University of Aalborg, Denmark; it can be used for the modeling and verification of real-time systems.…”

A malicious attack may endanger human life or pollute environment on a cyber-physical system (CPS). However, successfully attacking a CPS needs not only the knowledge of information technology (IT) but also the domain knowledge of the system's operation technology (OT). Therefore, it is critical to identify the vulnerabilities of a CPS. This paper proposes a systematic method for the security verification of a CPS, focusing on OT by using model checking with UPPAAL, so as to enhance cyber security. In our security analysis, we considered unsafe situations to be the result of a potentially effective security attack. Thus, we suggested a systematic method to generate security constraints based on the safety constraints (or safety checks) of the CPS and then enhance these security constraints by security verification using model checking with UPPAAL. UPPAAL's simulation tool can perform a detailed search for each state in various possible model combinations and can explore human-computer interactions more deeply. The contributions of our method are as follows: First, a systematic method is proposed to generate security constraints based on the overall safety requirements at the OT level. Second, the security constraints thus generated can be used for run-time monitoring to identify the possible security attacks when they are violated. Third, this paper proposes to augment normal system modeling with a suggested Attack Module to simulate the potential OT attacks. Finally, the verification results may be used in the following twofold directions: to identify the vulnerabilities for possible design improvements and to suggest the further additions of security constraints.

“…La verificación del control de un grupo de dos ascensores con estrategia de control colectivo fue abordado en [2] usando Spin. En este sentido, distintas herramientas como Spin, UPPAAL, y NuSMV, permiten la verificación de sistemas en tiempo real a partir de lógicas temporales [11]. Sin embargo, en el estudio de la bibliografía, no se ha encontrado ningún trabajo que aborde la verificación LTL de sistemas de ascensores con preselección de destino.…”

Los grupos de ascensores con sistema de preselección de destino persiguen la reducción del tiempo de espera en edificios de mediana y gran altura como hoteles o bloques de oficinas. En este tipo de sistemas, los pasajeros se dirigen al ascensor de acuerdo con el destino que hayan indicado en un panel exterior. El presente trabajo aborda la verificación del control de ascensores con preselección de destino mediante la aplicación de una herramienta software basada en lógica temporal lineal (LTL). En particular, se ha definido tanto el modelo del sistema como la especificaciones LTL mediante la herramienta de código abierto Spin. Como caso de estudio, se ha implementado el modelo de un grupo de dos ascensores en un edificio de cuatro plantas con paneles de preselección de destino en cada planta. El artículo ofrece resultados preliminares de simulaciones y verificaciones para un conjunto de fórmulas LTL definidas específicamente para este sistema.
