• ##### CIT/IUCC/DASC/PICom – Scalable Multi-group Key Management for AdvancedMeteringInfrastructure
2015 IEEE International Conference on Computer and Information Technology; Ubiquitous Computing and Communications; Dependable Autonomic and Secure Co, 2015

Abstract:

Advanced Metering Infrastructure (AMI) is composed of systems and networks to incorporate changes for modernizing the electricity grid, reduce peak loads, and meet energy efficiency targets. AMI is a privileged target for security attacks with potentially great damage against Infrastructures and privacy. For this reason, Key Management has been identified as one of the most challenging topics in AMI development. In this paper, we propose a new Scalable multi-group key management for AMI (SAMI) to secure data communications in an Advanced Metering Infrastructure. It is a key management scheme that can support unicast, multicast and broadcast communications based on an efficient multi-group key graph technique. An analysis of security and performance, and a comparison of our scheme with recently proposed schemes show that our solution induces low storage overhead (reduction reaches 83%) and low communication overhead (reduction reaches 99%) compared to existing solutions.

• ##### Efficient and Scalable multi-group Key management for AdvancedMeteringInfrastructure in Smart Grid
, 2015

Abstract:

Advanced Metering Infrastructure (AMI) is composed of systems and networks for measuring, collecting, storing, analyzing, and exploiting energy usage related data. AMI is an enabling technology for Smart Grid (SG) and hence represents a privileged target for security attacks with potentially great damage against Infrastructures and privacy. For this reason, security has been identified as one of the most challenging topics in AMI development, and designing an efficient Key Management Scheme (KMS) is one of first important steps. In this paper, we propose a new scalable and efficient key management scheme that we call Efficient and Scalable Multi-group Key Management (ESMKM) for secure data communications in an Advanced Metering Infrastructure. It is an efficient and scalable key management scheme that can support unicast, multicast and broadcast communications based on an efficient Multi-group Key graph technique. An analysis of security and performance, and a comparision of our scheme with recently proposed schemes show that our KMS can be used to reduce storage overhead (reduction reaches 87%) whithout increasing the communiction overhead.

• ##### interference mitigated zigbee based AdvancedMeteringInfrastructure
IEEE Transactions on Industrial Informatics, 2016
Co-Authors: Hao Ran Chi, Kim Fung Tsang, Kwok Tai Chui, Henry Shuhung Chung, Bingo Wingkuen Ling, Loi Lei Lai

Abstract:

An interference-mitigated ZigBee-based Advanced Metering Infrastructure (AMI) solution, namely IMM2ZM, has been developed for high-traffics smart Metering (SM). The IMM2ZM incorporates multiradios multichannels network architecture and features an interference mitigation design by using multiobjective optimization. To evaluate the performance of the network due to interference, the channel-swapping time $(\textit{T}_{\text{cs}})$ has been investigated. Analysis shows that when the sensitivity $(\textit{P}_{{\text{RX}}})$ is less than $-\text{12} \;\text{dBm}$ , $\textit{T}_{\text{cs}}$ increases tremendously. Evaluation shows that there are significant improvements in the performance of the application-layer transmission rate $(\sigma)$ and the average delay $\text{(D)}$ . The improvement figures are $\sigma>{\sim} \text{300}\%$ and $\textit{D}>\text{70}\%$ in a 10-floor building, $\sigma>{\sim} \text{280}$ % and $\textit{D}>\text{65}\%$ in a 20-floor building, and $\sigma>{\sim} \text{270}\%$ and $\textit{D}>\text{56}\%$ in a 30-floor building. Further analysis reveals that IMM2ZM results in typically less than 0.43 s delay for a 30-floor building under interference. This performance fulfills the latency requirement of less than 0.5 s for SMs in the USA (Magazine of Department of Energy Communications, USA, 2010). The IMM2ZM provides a high-traffics interference-mitigated ZigBee AMI solution.

• ##### AdvancedMeteringInfrastructure for Electric Vehicle Charging
Smart Grid and Renewable Energy, 2011
Co-Authors: Lun Ka Lam, Hoi Yan Tung, Hoi Ching Tung, Wah Ching Lee, Kim Fung Tsang, Loi Lei Lai

Abstract:

The widely adoption of Electric Vehicle (EV) has been identified as a major challenge for future development of smart grids. The ever increasing electric vehicle charging further increases the energy demand. This paper reports the development of an Advanced Metering Infrastructure (AMI) as an effective tool to reshape the load profile of EV charging by adopting appropriate demand side management strategy. This paper presents a total solution for EV charging service platform (EVAMI) based on power line and internet communication. It must be stressed that the development of Third Party Customer Service Platform in this investigation facilitates a single bill to be issued to EV owners. Hence, EV owners understand their energy usage and thus may perform energy saving activity efficiently. Experiment and evaluation of the proposed system show that the throughput achieved is about 5 Mbps at 10 ms end to end delay in Power line Communication. By introducing two dimensional dynamic pricing and charging schedule, the proposed EVAMI successfully reduces 36% peak consumption and increases the “off peak” consumption by 54%. Therefore the EVAMI does not only reduce the peak consumption but also relocates the energy demand effectively.
