Data transmission method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a data transmission method and device, electronic equipment and a storage medium. When the method is applied to a server, the method comprises the following steps: in response to a handshake request sent by a terminal, generating a key pair by adopting a first encryption algorithm, and sending a public key in the key pair to the terminal; receiving encrypted data sent by the terminal, and decrypting the encrypted data by using a private key in the key pair to obtain target data; if the authentication information passes the verification, generating permission information, and sending the permission information to the terminal, so that the terminal adopts the key to encrypt and decrypt access information, and accesses the server side according to the permission information. According to the technical scheme provided by the embodiment of the invention, the security of the data in the data transmission process and the high efficiency of encrypting and decrypting the transmitted data can be considered at the same time.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data encryption, and in particular, to a data transmission method, device, electronic equipment, and storage medium. Background technique [0002] Data encryption refers to converting plaintext into ciphertext through encryption algorithm and encryption key, and decryption refers to restoring ciphertext to plaintext through decryption algorithm and decryption key. At its core is cryptography. [0003] Data encryption remains one of the most reliable ways for computer systems to protect information. It uses cryptographic technology to encrypt information, realize information concealment, and thus play a role in protecting information security. According to different functions, data encryption technology can be divided into data transmission encryption technology, data storage encryption technology, data integrity authentication technology and key management technology.

AI Technical Summary

Problems solved by technology

[0005] If you want to improve the security of the data transmission method in the related technology, you generally use an asymmetric algorithm, which has relatively high security, but due to its asymmetric property, its encryption and decryption efficiency is low; if you want to improve the encryption and decryption efficiency, generally A symmetric encryption algorithm is used, and the encryption and decryption efficiency is high, but because the key used for encryption and decryption is symmetric, the security is relatively low

At present, there is no method that can ensure the efficiency of encryption and decryption while taking security into account.
