Method, equipment and system for encryption and decryption of data transmission

Abstract

The invention discloses a method, equipment and a system for encryption and decryption of data transmission, and belongs to the field of encryption technique. The method, the equipment and the system for the encryption and the decryption of the data transmission can achieve encryption and decryption operation of data rapidly, and improve processing efficiency. According to the method, the equipment and the system for the encryption and the decryption of the data transmission, a transport layer security (TLS) protocol is established between an encryption party and a decryption party, then the encryption party is connected with the decryption party through the TLS protocol, and the encryption party and the decryption party generate in a consult mode and store symmetric keys which are used for carrying out encryption and decryption operation on subsequent data. The method, the equipment and the system for the encryption and the decryption of the data transmission are mainly applied to encryption and decryption procedures of data.

Description

technical field [0001] The present invention relates to the technical field of encryption, in particular to an encryption and decryption method, device and system for data transmission. Background technique [0002] The existing technology uses a digital envelope to encrypt and transmit data with a small amount of data and low real-time requirements. The specific scheme is that the sender first uses an asymmetric encryption algorithm to encrypt the shared key with the public key of the receiver. Encryption, the shared key is a set of random numbers generated by the sender. Then encrypt the data with the encrypted shared key, and send the encrypted data to the receiver. After receiving the encrypted data, the receiver obtains the symmetric key through its own private key, and then uses the symmetric key to pair the data. to decrypt. In the process of realizing the above-mentioned encryption and decryption, the inventors found that at least the following problems existed in ...
