In this paper, we propose a multi-authority attribute-based signcryption\nscheme with efficient revocation for smart grid downlink communications. In the\nproposed scheme, grid operators and electricity vendors can send multicast\nmessages securely to different groups of consumers which is required in\ndifferent applications such as firmware update distribution and sending direct\nload control messages. Our scheme can ensure the confidentiality and the\nintegrity of the multicasted messages, allows consumers to authenticate the\nsource of the multicasted messages, achieves and non-repudiation property, and\nallows prompt revocation, simultaneously which are required for the smart grid\ndownlink communications. Our security analysis demonstrates that the proposed\nscheme can thwart various security threats to the smart grid. Our experiments\nconducted on an advanced metering infrastructure (AMI) testbed confirm that the\nproposed scheme has low computational overhead.\n
