Modern cyber physical systems (CPSs) has widely being used in our daily lives because of development of information and communication technologies (ICT). With the provision of CPSs, the security and privacy threats associated to these systems are also increasing. Passive attacks are being used by intruders to get access to private information of CPSs. In order to make CPSs data more secure, certain privacy preservation strategies such as encryption, and k-anonymity have been presented in the past. However, with the advances in CPSs architecture, these techniques also need certain modifications. Meanwhile, differential privacy emerged as an efficient technique to protect CPSs data privacy. In this paper, we present a comprehensive survey of differential privacy techniques for CPSs. In particular, we survey the application and implementation of differential privacy in four major applications of CPSs named as energy systems, transportation systems, healthcare and medical systems, and industrial Internet of things (IIoT). Furthermore, we present open issues, challenges, and future research direction for differential privacy techniques for CPSs. This survey can serve as basis for the development of modern differential privacy techniques to address various problems and data privacy scenarios of CPSs.

Differential Privacy Techniques for Cyber Physical Systems: A Survey

An exhaustive survey on security and privacy issues in Healthcare 4.0

As we all know that the technology is projected to be next to humans very soon because of its holistic growth. Now-a-days, we see a lot of applications that are making our lives comfortable such as smart cars, smart homes, smart traffic management, smart offices, smart medical consultation, smart cities, etc. All such facilities are in the reach of a common man because of the advancement in Information and Communications Technology (ICT). Because of this advancement, new computing and communication environment such as Internet of Things (IoT) came into picture. Lot of research work is in progress in IoT domain which helps for the overall development of the society and makes the lives easy and comfortable. But in the resource constrained environment of Wireless Sensor Network (WSN) and IoT, it is almost inconceivable to establish a fully secure system. As we are moving forward very fast, technology is becoming more and more vulnerable to the security threats. In future, the number of Internet connected people will be less than the smart objects so we need to prepare a robust system for keeping the above mentioned environments safe and standardized it for the smooth conduction of communication among IoT objects. In this survey paper, we provide the details of threat model applicable for the security of WSN and IoT based communications. We also discuss the security requirements and various attacks possible in WSN and IoT based communication environments. The emerging projects of WSNs integrated to IoT are also briefed. We then provide the details of different architectures of WSN and IoT based communication environments. Next, we discuss the current issues and challenges related to WSN and IoT. We also provide a critical literature survey of recent intrusion detection protocols for IoT and WSN environments along with their comparative analysis. A taxonomy of security and privacy-preservation protocols in WSN and IoT is also highlighted. Finally, we discuss some research challenges which need to be addressed in the coming future.

Intrusion Detection Protocols in Wireless Sensor Networks Integrated to Internet of Things Deployment: Survey and Future Challenges

Security and privacy of internet of medical things: A contemporary review in the age of surveillance, botnets, and adversarial ML

The Internet of Healthcare Things (IoHT) is an emerging intelligent pervasive framework that interconnects smart healthcare devices, stakeholders (e.g., doctors, patients, researchers, healthcare professionals, etc.), and infrastructure using smart sensors. Emergence of novel tools and techniques for data sensing and analysis during the last decade have allowed many researchers to develop and deliver services tailored for the IoHT. This resulted in a considerable number of research outcomes addressing the applications, challenges, and probable solutions targeting secured communication within the IoHT framework. Despite considerable efforts dedicated to it, secured service provisioning still remains as a major challenge. This work provides a detailed account on the current challenges and solutions towards providing secured service provisioning focusing on the IoHT attacks and countermeasures with an aim to facilitate more investigation in this area.

Towards Secured Service Provisioning for the Internet of Healthcare Things

Privacy Preservation in WSN for Healthcare Application

In today's technological world the Internet plays a significant role. Internet of Things (IoT) consists of a large number of wireless sensors and wearable sensors known as Things. These sensors are connected devices in a network and generate a vast amount of data. These sensors have limited storage and computing facility for elderly patient applications. Recently, the Internet of Things (IoT) has drawn considerable interest among the research community. Fog computing has several benefits for elderly healthcare applications such as security, efficient load distribution, and low-latency. Fog computing layer provides several advantages as improved doctor-patient relationships, reduction in medical treatment cost, and customized treatment for elderly patients. The main contribution of this article is to present a practical solution for elderly patients by taking advantage of fog computing for IoT based health systems. The system helps attendants and doctors by providing various healthcare vital parameters for preventive and corrective measures promptly.
