摘要
电网一次设备接线图纸的常规加密管理方法加密层少、加密算法老套,导致加密管理的隐写效果不佳,因此研究电网一次设备接线图纸数字化加密管理方法。该方法将接线图纸上传到管理控制平台中,采用Logistics混沌映射方法定义外部函数设计密钥,采用椭圆加密方法,利用有限数据群替换离散对数密码体系中的有限循环群,根据得到的新式密码体系设置加密算法,通过偏序集表现等级访问结构,以此实现对图纸的数字化加密管理。实验结果表明,与常规加密管理方法相比,所研究方法的加密算法下得到的密文差异大,对明文敏感性分析能力更强,最终的加密隐写效果更好。由此可见,所研究的加密管理方法更符合当下的加密管理要求。
The conventional encryption management method for wiring drawings of primary equipment of power grid has few encryption layers and old-fashioned encryption algorithm,which leads to poor steganography effect of encryption management.Therefore,the digital encryption management method for wiring drawings of primary equipment of power grid is studied.This method will be uploaded to the wiring drawings management control platform,the Logistics of chaotic mapping method design key external functions are defined,to use the ellipse encryption method.Using the limited data of replacing discrete logarithm finite cyclic group in the password system,according to the new password system encryption algorithm,the poset access structure performance level is used to realize the digital encryption management of drawings.The experimental results show that compared with the conventional encryption management method,the ciphertext obtained by the encryption algorithm presented in this paper is greatly different,it has stronger sensitivity analysis ability to plaintext,and the final encryption steganography effect is better.It can be seen that the encryption management method studied is more in line with the current encryption management requirements.
