Power data encryption transmission method, system and readable medium for resumption of work and production detection

Abstract

The invention aims to solve the problem of low data transmission security of a work resumption detection system, and provides a power data encryption transmission method and system for work resumptiondetection and a readable medium. The method comprises the steps: by an electric meter, generating a first random number and a first meter end secret key based on a first electric quantity value; generating a second meter end secret key according to a time parameter, the second random number and the current time of the electric meter; encrypting the current electric quantity value according to thefirst meter end secret key and the second meter end secret key; updating the first electric quantity value according to the current electric quantity value; by a host, generating a second host key based on the time parameter, the second random number and the current time of the host; according to the second electric quantity value and a second host secret key, generating the first host secret keyaccording to the first random number obtained after decrypting the second encrypted data according to the second electric quantity value and the second host secret key; updating the second electric quantity value according to the current electric quantity value obtained by decrypting the first encrypted data according to the first host secret key; and generating a second random number and sendingthe same to the electric meter. According to the technical scheme, the security of data transmission can be improved.

Description

technical field [0001] The invention belongs to the field of encryption, and in particular relates to a power data encryption transmission method, system and readable medium for detection of resumption of work and production. Background technique [0002] The resumption of work and production detection system collects the electricity consumption data of the enterprise based on the host computer, and based on the historical electricity consumption of the enterprise, the electricity consumption of the day and other data, and comprehensively considers the two factors of the proportion of electricity resumption of work and the proportion of the number of enterprises resuming work, to obtain the resumption index. Due to the large number of companies involved and the large amount of data, in order to ensure the efficiency of data transmission, power data transmission is generally encrypted using symmetric encryption algorithms. Although compared with asymmetric encryption algorithm...

Problems solved by technology

Due to the large number of companies involved and the large amount of data, in order to ensure the efficiency of data transmission, power data transmission is generally encrypted using symmetric encryption algorithms. Although compared with asymmetric encryption algorithms, symmetric encryption algorithms have higher encryption and decryption efficiency, but the key It is easy to leak, which will cause information leakage and cause security risks
