Authors - Priya Deokar, Sandhya Arora Abstract - Multiparty Computation (MPC) allows users to use their private inputs to compute a function without revealing anything about the inputs. This feature is useful in computing the aggregation of smart meter readings. The smart grid provides bi-directional communication between the smart meter and the utility supplier. Periodic sharing of fine-grained information by a smart meter presents a greater danger to privacy. Secure multiparty computing is one of the most efficient ways to preserve privacy among users. This paper briefly overviews MPC techniques and their usage in Smart Grid communication.
