Abstract

The invention provides a data transmission method, a data transmitting terminal and a data receiving terminal. The method comprises: a first encryption key is generated randomly; the first encryption key is encrypted by using a preset second encryption key based on an encryption algorithm; to-be-transmitted target data are encrypted by using the encrypted first encryption key and the encryption algorithm so as to generate a ciphertext of the target data; according to a preset combination rule, a combined ciphertext is generated by using the encrypted first encryption key and the ciphertext; and the combined ciphertext is sent to the data receiving terminal and thus the data receiving terminal splits the combined ciphertext according to a preset corresponding splitting rule to obtain the encrypted first encryption key and the ciphertext, and the ciphertext is decrypted by using a preset corresponding decryption algorithm and the encrypted first encryption key, so that the target data are obtained. Therefore, security of the data is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data transmission method, a data sending end and a data receiving end. Background technique [0002] In recent years, Internet technology has brought great convenience and fun to users' daily life and work, but it also brings many risks. In order to ensure that the data is stolen by an unlawful third party during the transmission process, and try not to cause data leakage, etc., it is usually necessary to encrypt the transmitted data. [0003] At present, before data transmission, the sender and receiver of the data must discuss the encryption key and save it by both parties. After that, the sender uses the stored encryption key to encrypt the data, and only the user with the encryption key Only the receiver can decrypt the data, so as to realize the encrypted transmission of the data. [0004] However, in the existing method, both the sending and receiving parties must kee...
