Abstract

The invention discloses a real-time perception hybrid encryption and decryption method and device for regulation and control operation data. The encryption method comprises the steps of obtaining real-time operation data; encrypting the real-time running data by adopting an MD5 algorithm to obtain an MD5 data ciphertext, and executing four rounds of operation by adopting eight pieces of initialization data by adopting the MD5 algorithm to generate a 256-bit MD5 data ciphertext; Combining the real-time operation data, the MD5 data ciphertext and the timestamp to obtain combined data; And encrypting the combined data by adopting an AES256 algorithm to obtain a combined data ciphertext, the round function of the AES256 algorithm comprising byte replacement transformation, row and column combination transformation and round key addition transformation. According to the invention, the integrity and security of real-time operation data can be improved.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a real-time perceptual hybrid encryption and decryption method and device for regulating and operating data. Background technique [0002] With the rapid development of mobile communication and Internet technology and the widespread popularization of smart terminals, mobile Internet technology has had a profound impact on the innovation of power grid business models and the improvement of operational efficiency. Power grid companies actively use Internet thinking, learn from "Internet +" successful cases, and actively design mobile business scenarios. While mobile applications bring many conveniences to smart grids, they also cause a series of security challenges. The control operation data has strong real-time performance and frequent interaction. The traditional mobile application information security protection is weak and the encryption method is lacking. In this way, t...
