Key Establishment

Extensive research effort is going on to contribute to the Cyber Physical system (CPS). It will create a physical system capable of computation, communication and sharing information between physical devices. Physical devices become smart devices because of CPS. CPS are engineered systems that are built with sensors, microcontrollers which performs computation, communication, control, process and analysis of physical objects. CPS playing important role in smart cities, home automations and other applications. Due to resource constraints like low processing power and low storage space there is a lack of standard security mechanism which can provide adequate security in CPS. In the research paper, we proposed Key establishment mechanism which prevents CPS from cyber-attacks. The goal of this research paper are six -folds: i) to give a detailed overview of cyber physical system. ii) To study architecture of CPS. iii) To study different attacks on CPS with attack points. iv)Application areas of CPS v) security threats in CPS vi) Key establishment algorithm to prevent cyber-attacks in CPS.

In recent years extensive research is going on for the development of applications which convert physical devices into smart devices. Industry 4.0 adopt the technologies under Cyber Physical Systems (CPS) for the development of such types of smart devices. Increase in the use of such type of smart devices without any security mechanism causes an open invitation for cyber attackers to perform cyber-attacks on such devices. Even current security algorithms are not efficiently work due to some constraints of smart devices. The goal of this research paper is to provide effective solution against different cyber-attacks on CPS applications. This paper proposed session key-based security mechanism which is used for the prevention of cyber-attacks and authentication of cyber devices.

Cyber-Physical System (CPS), a new generation of digital system, mainly focuses on complex interdependencies and integration between cyberspace and physical world. A CPS is composed of highly-integrated computation, communication, control, and physical elements. CPS is currently of interest in academia, industry, and government. However, a systematic and extensive review of research on CPS is not available. As such, this paper conducts an expanded literature review on applications of CPS by examining existing literatures from 2012 to 2017 in Scopus database. Specifically, 77 papers studying applications of CPS are grouped into 10 categories and reviewed. The contents of the papers in each research category are summarized. The challenges and trends of research on CPS are illustrated as well.

Sensing, distributed computation and wireless communication are the essential building components of a Cyber-Physical System (CPS). Having many advantages such as mobility, low power, multi-hop routing, low latency, self-administration, utonomous data acquisition, and fault tolerance, Wireless Sensor Networks (WSNs) have gone beyond the scope of monitoring the environment and can be a way to support CPS. This paper presents the design, deployment, and empirical study of an eHealth system, which can remotely monitor vital signs from patients such as body temperature, blood pressure, SPO2, and heart rate. The primary contribution of this paper is the measurements of the proposed eHealth device that assesses the feasibility of WSNs for patient monitoring in hospitals in two aspects of communication and clinical sensing. Moreover, both simulation and experiment are used to investigate the performance of the design in many aspects such as networking reliability, sensing reliability, or end-to-end delay. The results show that the network achieved high reliability - nearly 97% while the sensing reliability of the vital signs can be obtained at approximately 98%. This indicates the feasibility and promise of using WSNs for continuous patient monitoring and clinical worsening detection in general hospital units.
