Key Management Systems for Smart Grid Advanced Metering Infrastructure: A Survey
Smart Grids are evolving as the next generation power systems that involve
changes in the traditional ways of generation, transmission and distribution of
power. Advanced Metering Infrastructure (AMI) is one of the key components in
smart grids. An AMI comprises of systems and networks, that collects and
analyzes data received from smart meters. In addition, AMI also provides
intelligent management of various power-related applications and services based
on the data collected from smart meters. Thus, AMI plays a significant role in
the smooth functioning of smart grids.
AMI is a privileged target for security attacks as it is made up of systems
that are highly vulnerable to such attacks. Providing security to AMI is
necessary as adversaries can cause potential damage against infrastructures and
privacy in smart grid. One of the most effective and challenging topic's
identified, is the Key Management System (KMS), for sustaining the security
concerns in AMI. Therefore, KMS seeks to be a promising research area for
future development of AMI. This survey work highlights the key security issues
of advanced metering infrastructures and focuses on how key management
techniques can be utilized for safeguarding AMI. First of all, we explore the
main features of advanced metering infrastructures and identify the
relationship between smart grid and AMI. Then, we introduce the security issues
and challenges of AMI. We also provide a classification of the existing works
in literature that deal with secure key management system in AMI. Finally, we
identify possible future research directions of KMS in AMI
Foundations and Technological Landscape of Cloud Computing
The cloud computing paradigm has brought the benefits of utility computing to a global scale. It has gained paramount attention in recent years. Companies are seriously considering to adopt this new paradigm and expecting to receive significant benefits. In fact, the concept of cloud computing is not a revolution in terms of technology; it has been established based on the solid ground of virtualization, distributed system, and web services. To comprehend cloud computing, its foundations and technological landscape need to be adequately understood. This paper provides a comprehensive review on the building blocks of cloud computing and relevant technological aspects. It focuses on four key areas including architecture, virtualization, data management, and security issues
