SecGrid: A Secure and Efficient SGX-Enabled Smart Grid System With Rich Functionalities

Abstract

Smart grid adopts two-way communication and rich functionalities to gain a positive impact on the sustainability and efficiency of power usage, but on the other hand, also poses serious challenges to customers' privacy. Existing solutions in smart grid usually use cryptographic tools, such as homomorphic encryption, to protect individual privacy, which, however, can only support limited and simple functionalities. Moreover, the resource-constrained smart meters need to perform heavy asymmetric cryptography in these solutions, which is not applied to smart grid. In this paper, we present a practical and secure SGX-enabled smart grid system, named SecGrid. Our system leverage trusted hardware SGX to ensure that grid utilities can efficiently execute rich functionalities on customers' private data, while guaranteeing their privacy. With the designed security protocols, the SecGrid only require the smart meters to perform AES encryption. Security analysis shows that SecGrid can thwart various attacks from malicious adversaries. Experimental results show that SecGrid is much faster than the existing privacy-preserving schemes in smart grid.

Power systems automation, communication, and information technologies for smart grid: A technical aspects review

“…However, the continuous usage of conventional resources(coal and petroleum products) results in their depletion, although they assure constant power supply. In addition, the emission of greenhouse gases from conventional resources affects the  ISSN: 1693-6930 ecology [33]. Hence, RES and sustainable energy resources are becoming an alternative and necessary factor in generating power, but there is a need to assure the quality of power.…”

“…The growth of the energy sector could be curtailed in an instance when the transmission system remains stagnant. Some important building blocks of transmission system s are, PMU, phasor data collector (PDC), FACTS, advanced storage apart from the ever-increasing transmission in case of HVDC and HVAC, wide-area monitoring, and WAMPAC assures reliable transmission system [17][18][19]33]. Although the capabilities of the transmission system can sustain the current load, SG implementation on a larger power system scale would have to upgrade the capacity of the transmission system prompting a considerable influx of capital [44].…”

FDIPP: False Data Injection Prevention Protocol for Smart Grid Distribution Systems

“…Garg et al in [27,28] introduce lightweight authentication schemes for resource-constrained smart meters and generally for Internet-of-things devices, respectively. Other authors, such as in [29], propose a privacy-preserving scheme for resource-constrained smart meters.…”

Lightweight Privacy-Preserving Raw Data Publishing Scheme

“…However, in some application scenarios, the average, maximum or minimum of data cannot meet the needs, a variety of fine-grained data is required. Recently, a privacy-preserving computing function library is designed based on Intel Software Guard Extensions (SGX) [12]. However, Intel SGX may suffer from attack such as side-channel attack [13].…”
