4G communication encryption algorithm based on time

Abstract

The invention discloses a 4G communication encryption algorithm based on time, and the specific method comprises the steps that: timing is carried out between a main station and a terminal before themain station and the terminal interact with a to-be-encrypted message each time; the master station and the terminal record effective timing moments and acquire the same time information based on theeffective timing moments; the master station and the terminal respectively take the time information as an authentication identifier in the interaction task; during encryption interaction, a sender combines the authentication identifier with an original message to form a to-be-sent message, and then encrypts and sends the to-be-sent message; and after receiving the message, a receiver analyzes theauthentication identifier in the message and checks whether the authentication identifier in the message is consistent with a locally recorded authentication identifier or not, thereby judging whether the received message is valid or not. The method can solve the problems of repetition, ineffectiveness, fake message operation and the like of the current interaction task, improves the interactionefficiency, and realizes safe and reliable data transmission.

Description

technical field [0001] The invention relates to a communication encryption algorithm, in particular to a time-based 4G communication encryption algorithm for electricity collection. Background technique [0002] With the deepening and popularization of the application of HPLC technology, the collection volume of stations is becoming more and more diverse, and the communication business between the terminal and the main station needs to achieve faster, more accurate, safer and more reliable functional requirements. [0003] In practical applications, there are problems such as repeated and invalid operations on the current interactive tasks by the master station and the terminal, and there are even criminals who intercept the communication messages of the master station and the terminal, so as to tamper with commands, data or set parameters, and forge messages to interfere with normal operations. communication process. Contents of the invention [0004] The present inventi...
