摘　　要：以往使用传统RSA算法、神经网络算法的密钥长,签名和验签速度慢,导致监控效果不佳,针对该现象,提出了基于SM2密码体系的电力信息安全监控系统设计。根据系统硬件结构,采用DS18B20传感器计量数据采集时钟脉冲,完成电力信息采集。设计间歇振荡服务加密接口电路,控制系统电压和电流。通过视频联动,达到监控互动与协调,实现远程操控。部署SM2加密安全组件,决定用户资源访问权限。依据SM2椭圆曲线公钥密码算法原理,使用少量密钥完成信息加密,根据对称加密方式,改善传统方法签名和验签速度慢的问题,由此设计安全访问流程。通过实验结果可知,该系统密钥短,签名速度和验签速度快,具有良好的安全监控性能。In the past,traditional RSA algorithm and neural network algorithm were used for long key,slow signing speed and check speed,which led to poor monitoring effect.Aiming at this phenomenon,a power information security monitoring system design based on SM2 cryptosystem was proposed.According to the hardware structure of the system,the measurement data acquisition clock pulse of DS18 B20 sensor is adopted to complete the power information acquisition.Design intermittent oscillation service encryption interface circuit,control system voltage and current. Through video linkage,monitoring interaction and coordination can be achieved,and remote control can be realized.Deploy the SM2 encryption security component to determine user resource access rights.According to the principle of SM2 elliptic curve public key cryptography algorithm,a small number of keys are used to complete the information encryption,and according to the symmetric encryption method,the problem of slow signing speed and check speed of traditional methods are improved,thus the secure access flow is designed.The experimental results show that the system has short key,fast signature and check speed,and good security monitoring performance.
