At present, a rather big challenge to model cyber-physical systems is to stand for the interactions between physical level and cyber level. Researchers are faced with the trouble in the analysis of information security property of noninterference in cyber-physical systems because of the physical components and behavior appended to cyber components and systems. A new method is put forward with P...

Physical layer security which safeguards data confidentiality based on the information-theoretic approaches has received significant research interest recently. The key idea behind physical layer security is to utilize the intrinsic randomness of the transmission channel to guarantee the security in physical layer. The evolution towards 5G wireless communications poses new challenges for physic...

Background and Goal: ICT development in recent years has created excellent developments in human social and economic life. One of the most important opportunities to use information technology is in the medical field, that the result would be electronic health record (EHR).The purpose of this research is to investigate the effects information securi...

We analyze three different scenarios for security in TV series “24” and compare these scenarios with respect to physical security. We apply “security engineering” to analyze these scenarios and find that these scenes are farfetched from reality.

Cyber-Physical Systems (CPSs) are characterized by integrating computation and physical processes. The theories and applications of CPSs face the enormous challenges that are (1) general workflow of cyber physical systems, (2) identifying the unique properties of cyber-physical systems and (3) discussing security mechanisms applicable to cyber physical systems. In particular, we analyze and we ...

The design of security for cyber-physical systems must take into account several characteristics common to such systems. Among these are feedback between the cyber and physical environment, distributed management and control, uncertainty, real-time requirements, and geographic distribution. This paper discusses these characteristics and suggests a design approach that better integrates security...

In this work, we propose a novel MIMO-aided security scheme. By exploiting an extra dimension provided by MIMO systems for adding artificial noise to the transmission process, the physical-layer security is enhanced as a result. In the proposed scheme the physical-layer may rely on upper-layer encryption techniques for security, which results in a cross-layer security scheme.

Data security at the physical layer of optical networks, or optical layer security, has received considerable research attention due to the rapid growth of optical network capacity [1]. Among various optical layer approaches, optical codedivision multiple access (OCDMA) systems are considered to be promising because of the physical encoding and decoding processes comprising these systems. Gener...
