SecGrid: A Secure and Efficient SGX-enabled Smart Grid System with Rich Functionalities
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
