    Cybersecurity and Network Performance Modeling in Cyber-Physical Communication for BigData and Industrial IoT Technologies
    (IEEE, 2019-07-26) Sen, S; Jayawardena, C
    The information and networking technology have been revolutionized with the inception of recent evolution of Cyber-Physical Systems (CPS) and the Internet of Things (IoT). The next generation distributed computing systems i.e., CPS and IoT are highly interconnected and deeply embedded with the physical world. By capitalizing the advantages and opportunities of these technologies, Industrial-IoT has been fueling smart industrial processes. The execution and application of these processes generate huge amount of data, which leads the distributed computing systems to carefully consider information and data management reliably and securely; also facilitating the necessary automation as well as ensuring timely information exchange. But the current internet doesn't guarantee the network performance and secure transportation; in addition the physical systems are becoming more insecure when interconnected to the cyber systems. These bottlenecks are leading to the necessity of improving performance and security in the cyber-physical communication. Considering those pervasive requirements, this paper has modeled network performance as well as system security with a view to improve these components which could heel the reliable cyber-communication challenges.

    Reliability and Cybersecurity Improvement Strategies in Wireless Sensor Networks for IoT-enabled Smart Infrastructures
    (IEEE, 2019-10-18) Sen, S; Jayawardena, C
    IoT-enabled smart applications and infrastructures use low power wireless sensor networks widely. But due to low energy and lack of computing capabilities, the comprehensive use of such devices result in reliability and security vulnerabilities. Therefore, the lower capability of sensor devices need to operate wisely with careful technical considerations to maximize their capabilities. This paper proposes a new technique to improve reliability and cybersecurity by balanced use of sensor energy while maintaining the quality of communication. The simulation result shows that the strategy proposed is effective. A hacking strategy has also been detailed so that the security experts can consider those while designing a security suite for IoT-enabled infrastructures.
