Abstract

The invention provides a data transmission encryption method, device, storage medium, equipment and server. The data transmission encryption method applied to a server-side comprises the following steps: receiving a public key of an equipment-side sent by the equipment-side; generating a session key, and encrypting the session key by using the public key of the equipment-side; and sending the encrypted session key to the equipment-side, thereby facilitating the equipment-side to communicate with the server-side through the session key. Through the technical scheme provided by the invention, the safe and reliable data transmission is guaranteed by adopting a way of combining a symmetric encryption algorithm with an asymmetric encryption algorithm. The asymmetric encryption is used for transmitting the session key, the symmetric encryption is used for data encryption, thereby guaranteeing the security of the data transmission, and guaranteeing the encryption efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission encryption method, device, storage medium, equipment and server. Background technique [0002] Currently commonly used encryption techniques are generally divided into two categories: "symmetric" and "asymmetric". Symmetric encryption uses the same key for encryption and decryption, usually called a "session key". Asymmetric encryption means that encryption and decryption do not use the same key, usually there are two keys, called "public key" and "private key", and they must be used in pairs, otherwise the encrypted file cannot be opened. The "public key" here refers to something that can be released to the outside world, while the "private key" cannot, and can only be known by the holder. Because if the symmetric encryption method is to transmit encrypted files on the network, it is difficult not to tell the other party the key, no matter wh...
