摘要
运通过有效融合Shamir(t,n)门限密钥共享方案和Laplace噪音干扰算法提出了一种面向智能电表隐私保护的电量请求方案,实现电力公司分时电价计费的同时保护用户隐私.定量分析了安全性并确定了最优门限值t的选择、测试分析了时间效率、验证分析了Laplace噪音干扰的ε-差分隐私保护效果并作了方案的可行性比较.实验结果表明,提出的方案具有有效性和可行性.
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.
