“…• Confidentiality: Confidentiality as from the perspective of AMI can be perceived as privacy of consumer's consumption pattern and information, i.e., consumption information must remain confidential. This means physical theft of meter to access the stored data, unauthorized access to the data by other connected automated systems through gateways, as well as customers access to other customers information should be prevented [45]. At AMI head end, customer information shall remain confidential and only authorized systems will have access to certain sets of data.…”

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.

Abstract:The subject of cyber-security and therefore cyber-attacks on smart grid (SG) has become subject of many publications in the last years, emphasizing its importance in research, as well as in practice. One especially vulnerable part of SG are smart meters (SMs). The major contribution of simulating a variety of cyber-attacks on SMs that have not been done in previous studies is the identification and quantification of the possible impacts on the security of SG. In this study, a simulation model of a nanogrid, including a complete household with an SM, was developed. Different cyber-attacks were injected into the SM to simulate their effects on household nanogrid. The analysis of the impacts of different cyber-attacks showed that the effects of cyber-attacks can be sorted into various categories. Integrity and confidentiality attacks cause monetary effects on the grid. While, availability attacks have monetary effects on the grid as well, they are mainly aimed at compromising the SM communication by either delaying or stopping it completely.

“…Advanced Metering Infrastructure (AMI) has been regarded as a key component of the smart grid. It inherits the two-way communication capability of smart grid and introduces new opportunities for consumers and suppliers: it is responsible for collecting consumer's time-based data and transmitting them to the AMI host system, and it is also responsible for implementing price signals and control commands to perform necessary control actions [3]. AMI is a privileged target for security attacks with potentially great damage against infrastructures and privacy.…”

The Smart Grid (SG) is widely considered to be the informationization of the power grid. Advanced Metering Infrastructure (AMI) has been regarded as a key component of the SG. The critical role of AMI in the SG has made this system a privileged target of cyber attacks. Consequently, AMI security is of very high importance for the security of the SG. For this reason, Key Management has been identified as one of the most challenging topics in AMI development because of the great scale of SG and dynamism of connected clients with respect to tariff programs. This paper proposes a new efficient Multi-group Key management for AMI (MK-AMI) to secure data communications in the smart grid. It is a novel key management scheme that can support unicast, multicast and broadcast communications. An analysis of security and performance, and a comparison of our scheme with recently proposed schemes illustrate that MK-AMI achieves efficient key management and induces low storage and communications overheads compared to existing solutions.
