Effective Development

This paper presents a co-simulation platform which combines a building simulation tool with a Cyber-Physical Systems (CPS) approach. Residential buildings have a great potential of energy reduction by controlling home equipment based on usage information. A CPS can eliminate unnecessary energy usage on a small, local scale by autonomously optimizing equipment activity, based on sensor measurements from the home. It can also allow peak shaving from the grid if a collection of homes are connected. However, lack of verification tools limits effective development of CPS products. The present work integrates EnergyPlus, which is a widely adopted building simulation tool, into an open-source development environment for CPS released by the National Institute of Standards and Technology (NIST). The NIST environment utilizes the IEEE High Level Architecture (HLA) standard for data exchange and logical timing control to integrate a suite of simulators into a common platform. A simple CPS model, which controls local HVAC temperature set-point based on environmental conditions, was tested with the developed co-simulation platform. The proposed platform can be expanded to integrate various simulation tools and various home simulations, thereby allowing for co-simulation of more intricate building energy systems.

A New Technique

Recently, optimistic fair exchange in electronic commerce (e-commerce) or mobile commerce (m-commerce) has made great progress. However, new technologies create large amounts of data and it is difficult to handle them. Fortunately, with the assistance of cloud computing and big data, optimistic fair exchange of digital items in cyber-physical systems (CPSes) can be efficiently managed. Optimistic fair exchange in cloud-assisted CPSes mainly focuses on online data exchange in e-commerce or online contracts signing. However, there exist new forms of risks in the uncertain network environment. To solve the above problems, we use a new technique called verifiably encrypted identity-based signature (VEIS) to construct optimistic fair exchange in cloud-assisted CPSes. VEIS is an encrypted signature, and we can check the validity of the underlying signature without decrypting it. We introduce a robust arbitration mechanism to guarantee fairness of the exchange, and even the trusted third party (TTP) cannot get the original signatures of the exchange parties. And the TTP in our protocol is offline, which greatly improves the efficiency. Besides, we show that our protocol is secure, fair, and practical.

At present, an increasing number of researchers and specialists in the construction industry come to the opinion that it is advisable to use a number of technologies (BIM, Smart City, Big Data, IOT and others) in the practice of construction (in the broad sense of this concept), which are united by the concept of the Fourth Industrial Revolution. The result of the implementation of these technologies in the construction should be the transition to the widespread use of cyber-physical systems. The problem of using information technologies in construction today is not due to the lack of this process as such, but to the lack of consistency and consistency in it. Fragmentary nature of the application, inconsistency of the applied technologies at different levels of management and at different stages of the life cycle of construction projects sharply reduce the potential positive effect of informatization and building automation. At the same time, the concept of cyber-physical systems, that is, the integration at the system level of physical processes and controls has proven effective in industrial production. The approaches to ensuring the processes of designing cyber-physical building systems through the development and application of General mathematical models for the processes of data exchange and management are considered. The presented models of data exchange and management of cyber-physical building systems describe the processes implemented at each stage of the life cycle of cyber-physical building systems. Functional blocks of the considered models allow to describe the processes of data collection, storage and processing on the current and past stages of the life cycle of cyber-physical construction systems. The presented models are the elements of mathematical support of the processes of designing cyber-physical building systems, which determine the processes of information exchange and management between the structures of cyber-physical building systems of different levels of hierarchy in the full life cycle.

The recent proliferation of embedded cyber components in modern physical systems [1] has generated a variety of new security risks which threaten not only cyberspace, but our physical environment as well. Whereas earlier security threats resided primarily in cyberspace, the increasing marriage of digital technology with mechanical systems in cyber-physical systems (CPS), suggests the need for more advanced generalized CPS security measures. To address this problem, in this paper we consider the first step toward an improved security model: detecting the security attack. Using logical truth tables, we have developed a generalized algorithm for intrusion detection in CPS for systems which can be defined over discrete set of valued states. Additionally, a robustness algorithm is given which determines the level of security of a discrete-valued CPS against varying combinations of multiple signal alterations. These algorithms, when coupled with encryption keys which disallow multiple signal alteration, provide for a generalized security methodology for both cyber-security and cyber-physical systems.
