A Multi-Authority Attribute-Based Signcryption Scheme with Efficient Revocation for Smart Grid Downlink Communication
In this paper, we propose a multi-authority attribute-based signcryption
scheme with efficient revocation for smart grid downlink communications. In the
proposed scheme, grid operators and electricity vendors can send multicast
messages securely to different groups of consumers which is required in
different applications such as firmware update distribution and sending direct
load control messages. Our scheme can ensure the confidentiality and the
integrity of the multicasted messages, allows consumers to authenticate the
source of the multicasted messages, achieves and non-repudiation property, and
allows prompt revocation, simultaneously which are required for the smart grid
downlink communications. Our security analysis demonstrates that the proposed
scheme can thwart various security threats to the smart grid. Our experiments
conducted on an advanced metering infrastructure (AMI) testbed confirm that the
proposed scheme has low computational overhead
