Classification of Teleparallel Homothetic Vector Fields in Cylindrically Symmetric Static Space-Times in Teleparallel Theory of Gravitation

引用

Communications in Theoretical Physics 2010年第10期54卷 675-678页

作者： Ghulam Shabbir suhail Khan Faculty of Engineering Sciences GIK Institute of Engineering Sciences and Technology

In this paper we classify cylindrically symmetric static space-times according to their teleparallel homothetic vector fields using direct integration technique. It turns out that the dimensions of the teleparallel homothetic vector fields are 4, 5, 7 or 11, which are the same in numbers as in general relativity. In case of 4, 5 or 7 proper teleparallel homothetic vector fields exist for the special choice to the space-times. In the case of 11 teleparallel homothetic vector fields the space-time becomes Minkowski with all the zero torsion components. Teleparallel homothetic vector fields in this case are exactly the same as in general relativity. It is important to note that this classification also covers the plane symmetric static space-times.

An Improved Security Scheme for IEC 61850MMS Messages in Intelligent Substation Communication Networks

引用

Journal of Modern Power Systems and Clean Energy 2020年第3期8卷 591-595页

作者： Taha Selim Ustun S.M.suhail Hussain Fukushima Renewable Energy Institute AIST(FREA)FukushimaJapan Research Institute of the Energy Frontier TsukubaJapan

Advanced connectivity in substations brings along cybersecurity considerations. Especially, the use of standardized data objects and message structures stipulated by IEC 61850 makes them much more vulnerable to unauthorized access and manipulation. In order to tackle these vulnerabilities, different methods are investigated by researchers all over the world. An important aspect of such efforts is the real-time performance consideration since power systems are bound by the rules of physics and all control/communication tasks need to be completed in a certain time frame. Security schemes for substation communication have been proposed in the recent literature. However, they must be improved to ensure a full security solution. Recently published IEC 62351 standard aims to fill this gap. Node authentication is vital for substation communication networks based on IEC 61850 to mitigate a variety of attacks such as man-in-the-middle(MITM) attack. This short communication presents a node authentication mechanism based on transport layer security(TLS) with certificates to address this knowledge gap. It also investigates the real-time performance by implementing the proposed scheme with Python.
