Abstract

A privacy-preserving power request scheme was proposed. The proposed scheme combined Shamir (t,n) threshold secret sharing scheme with Laplace noise perturbation algorithm effectively to achieve paying TOU billing as well as protecting user privacy. Experiments were performed from four aspects:analyzing the security quantitatively and determining the optimal threshold t, giving the experiment on efficiency test, verifying the ε-differential privacy by introducing the Laplace noise perturbation and conducting the scheme feasibility comparison. Experimental results show that the proposed scheme is effective and feasible.

Key words： smart meter; privacy-preserving; secret sharing; Laplace noise
