Problems solved by technology

However, to encrypt the transmitted data through AES, the security of the key depends on the acquisition method and storage of the key, and the current key acquisition method and storage make the transmission data encrypted by AES less secure

Abstract

The invention relates to the technical fields of cryptography, information encryption and decryption and symmetric encryption, and provides a data transmission encryption method, which comprises the following steps of: obtaining a current data storage request, and generating a first token and a first random bit according to the current data storage request; Extracting to-be-stored data contained in the current data storage request, and performing AES encryption on the to-be-stored data based on the first token and the first random bit to obtain a first key; And performing md5 encryption on thefirst key to obtain a ciphertext data packet. When the front end receives the data storage request once, the data needing to be transmitted at the time is encrypted and transmitted to the rear end, the rear end verifies the password of the data transmission, and when the password is incorrect, the rear end refuses the data storage request at the time. And the front end dynamically generates the password through the AES every time, so that the security of data transmission is improved. And through the AES cryptographic algorithm, the adjustment is convenient, the password cracking difficulty is increased, and the data transmission security is improved again.

Description

technical field [0001] The invention relates to the technical fields of encryption technology, information encryption and decryption, and symmetric encryption, and in particular to a data transmission encryption method, device, storage medium, and server. Background technique [0002] With the development of various application systems, the security of data on the Internet has been paid attention to, especially for some businesses with relatively high data security requirements; such as banking, military industry, securities and other industries. Data is widely transmitted on the Internet and may be intercepted at any time. If the data is sent in clear text, the security of the data is not guaranteed. At the same time, in some industries, there are many customers and great business needs. If a fixed encryption key is used to transmit related data, there will be a lot of problems in managing various keys. RSA and AES encryption algorithms are commonly used for encrypted tran...
