摘　　要：为保证智能电网隐私数据不会被恶意入侵,基于近似匹配模型,提出电网数据隐私防护建模方法。通过匹配结构的代价函数,得到无标签节点的语义匹配值,计算隐私防护近似匹配代价;结合近似匹配模型制定访问控制策略,分别构造数据源文件、认证机构、授权机构的子函数,得到访问过程中数据源文件加密与解密的模型。对多维数据进行加密聚合,建立公共参数,得到数据加密的密文格式,从而实现电网数据的隐私防护。实验结果表明,方法对于数据隐私的防护效果好。In order to ensure that the private data of smart grid will not be invaded maliciously,the modeling method of power grid data pri-vacy protection is designed based on approximate matching model.The semantic matching value of unlabeled nodes is obtained through the cost function of the matching structure,and the approximate matching cost of privacy protection is calculated;The ac-cess control strategy is formulated by combining the approximate matching model,and the sub functions of the data source file,the certification authority,and the authorization authority are constructed respectively to obtain the data source file encryption and decryption model during the access process.The multi-dimensional data is encrypted and aggregated,and the public parame-ters are established to obtain the encrypted ciphertext format of the data,so as to realize the privacy protection of the power grid data.The experimental results show that the method has good effect on protecting data privacy.
