【摘要】 针对10k V以下配电网自动化系统采用公网传输控制指令时存在的安全问题及安全需求,提出了一种基于ECC算法的配电网自动化系统安全机制。采用ECC签名算法和加密算法实现了主站和子站终端的身份认证,采用哈希函数实现了传输信令的完整性认证,ECC加密算法实现了信令数据传输的保密性,并用Java语言搭建了系统仿真平台,并对相关性能进行了测试分析。更多还原

【Abstract】 Aimed at the problems and the security requirements of 10 k V power network distribution automation system transmitting control data based on GSM / CDMA / TD-SCDMA,a set of security mechanisms is designed,which is based on ECC( elliptic curves cryptography). The identity authentication between sub-station and distribution terminal unit is actualized by using ECC-signature algorithm. Transmission signal integrity is actualized by Hash function and data encryption is actualized by ECC encryption schemes. We develop a GUI( Graphical User Interface) as the simulation platform by using java language and analyze the testing performance.更多还原
