A Concealed Based Approach for Secure Transmission in Advanced Metering Infrastructure

Abstract

The smart grid has an important subsystem known as the Advanced Metering Infrastructure (AMI), responsible for measuring customer consumption of electricity. The AMI subsystem has smart meters as one of the components and they play a vital role in enabling communication between the utility provider and consumers. Smart meters can report real-time electricity consumption readings of the consumer to the utility. Securing this communication link from attacks remain very important for the secure transmission of readings. Different methods or approaches have been developed in the past and most of the works have high computational overheads. This paper proposes a lightweight Concealed Based Security Scheme (CBSS) for secure transmission within the AMI, providing authentication, reducing the computational overheads and energy consumption during transmission. The CBSS method is compared with the AMI Data Communication Scheme (ADCS) which does not have authentication process. The network is built in the Network Simulator 2 environment, showing the communication between the nodes. Further security is provided using a simple encryption/decryption method of 2 random numbers. The contribution of this paper is the proposed lightweight method for the AMI that authenticates the transfer of data between smart meters and other components of the AMI system. The paper also contains a simulation evaluation for the chosen design parameters of the resemblance of AMI network. The simulations show an improvement of 5% in delivery ratio, 3% throughput and 4% on energy consumed when adding security to the network.

Privacy and security of advanced metering infrastructure (AMI) data and network: a comprehensive review

“…A lightweight concealed-based security scheme (CBSS) as a secure network for communication/transmission in AMI was proposed [67]. This was achieved via the network simulator 2 environment together with direct encryption and decryption of any 2 arbitrary prime numbers.…”

“…-Implementing network traffic monitoring and filtering tools -Deploying firewalls and intrusion prevention and detection systems (IPS and IDS) -Maintaining redundant infrastructure to mitigate the impact of DoS attacks [83] These target the availability of the AMI system, such as flooding the network with excessive traffic or overwhelming system resources Inadequate encryption of data transmitted between smart meters and the central AMI system [67].…”

BSCSML: Design of an Efficient Bioinspired Security &Privacy Model for Cyber Physical System using Machine Learning

“…Because cyber-Physical systems are becoming more and more pervasive in our everyday lives, concerns regarding their privacy and security have become increasingly important for real-time scenarios via Privacy-aware Reconfigurable Secure-Firmware Updating Framework (PRSUF) [1,2,3]. These systems, which combine the real and virtual worlds, have been implemented in a variety of fields, including healthcare, transportation, and energy production levels [4,5,6]. Because of the critical nature of these systems, cybercriminals are likely to target them under different attacks.…”

Monthly Probability Theoretical Line Loss Calculation Method of Low Voltage Distribution Network Based on Simultaneous Power and Electricity

“…Among all levels of power grids, the line loss of LVN is the most severe, which is one of the important reasons for the overall high line loss rate in the power grid. The potential for reducing losses in LVN is enormous, and it is an important part of online loss management and reduction work for power grid enterprises [6] .…”
