Abstract

The invention provides a sectional encryption transmission method, comprising: acquiring data to be encrypted; dividing the data to be encrypted into multiple data sections; recording relative positions of the data sections in the data to be encrypted; encrypting the data sections respectively based on a preset encryption algorithm to obtain sectional cyphertexts; combining the sectional cyphertexts into a complete cyphertext according to the relative positions of the data sections in the data to be encrypted; transmitting the complete cyphertext to a decoding terminal. Compared with the prior art where data to be encrypted is encrypted and transmitted directly, the method provided herein has a greatly reduced amount of data to be encrypted each time, may have lowered requirements on hardware and has lower cost of data encryption transmission.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a segmented encryption transmission method and device. Background technique [0002] In communication technology, in order to improve the security of communication, the content of communication is generally encrypted. Encryption is to use a special algorithm to change the original information data, so that even if unauthorized users obtain the encrypted information, they still cannot understand the content of the information because they do not know the decryption method. [0003] In the prior art, for encrypted transmission of files, a common method is to encrypt the entire file and then transmit it through the network. Due to the large amount of information to be encrypted, the hardware requirements are high, which increases the cost of encrypted file transmission. [0004] Therefore, it is desirable to have a method that can realize fast encrypted transmission with low h...
