摘　　要：传统的主动配电网终端数据联合分层加密技术加密有效率低,不能完整地保存数据。为此提出一种新的主动配电网终端数据联合分层加密技术,在操作系统、DBMS内核层、DBMS外层进行加密,利用序列密码加密与分组密码加密设计了对称加密算法,通过RSA算法推导非对称加密算法,引入密钥管理实现终端加密。为检测技术效果进行对比实验,结果表明,所提的主动配电网终端数据联合分层加密技术能够完整地保存数据,且具有较高的加密有效性,更适合电网发展。Traditional active distribution network terminal data combination layered encryption technology encryption efficiency is low,can not completely save data.This paper proposes a new active distribution network terminal data combination layered encryption technology,encryption in the operating system,DBMS kernel layer,DBMS outer layer,using sequence cipher encryption and block cipher encryption design symmetric encryption algorithm,through RSA algorithm to derive asymmetric encryption algorithm,the introduction of key management to achieve terminal encryption.The results show that the proposed combined hierarchical encryption technology for terminal data of active distribution network can save data completely and has high encryption effectiveness,which is more suitable for the development of power grid.
