摘　　要：为了提高电力业务数据的安全性,基于同态加密过程提出了一种新的电力业务数据安全性设计方法。首先构建电力业务数据分析和编码模型,采用向量量化编码方法进行电力业务数据的编码设计和同态加密。然后设计电力业务数据的数据加密密钥协议,结合线性空间结构重组方法实现加密过程的数据结构重构,并建立数据特征分析模型。在此基础上,通过算术编码加密设计技术实现编码再分析,并通过深度融合算法完成密钥置乱性设计,提高电力业务数据的加密安全性和抗攻击能力。仿真结果表明,应用该方法实现电力业务数据加密过程的随机置乱性较好、抗攻击能力较强,有效提高了电力业务数据的安全性。In order to improve the security of power service data,this paper proposes a new security design method based on homomorphic encryption process.Firstly,a power service data analysis and coding model is constructed,and the vector quantization coding method is used to encode and encrypt the power service data.Then,the data encryption key protocol of power business data is designed,and the data structure reconstruction in the encryption process is realized by combining the linear spatial structure recombination method,and the data feature analysis model is established.On this basis,coding reanalysis is realized through arithmetic coding and encryption design technology,and key scrambling design is completed through deep fusion algorithm,so as to improve the encryption security and anti-attack ability of power business data.The simulation results show that this method has good randomness and strong anti-attack ability in power service data encryption process,and effectively improves the security of power service data.
