Embodiment Construction

[0025] refer to figure 1 , a data transmission method proposed by the present invention, in the process of sending the data packet, the cloud server encrypts the data packet, and then the cloud server sends the encrypted data packet and the decryption key to the receiving terminal respectively.

[0026] In this way, in this embodiment, the encryption of the data packet during the transmission process is realized. Compared with the existing data packet encryption and transmission, the encryption process and encryption mode of the data packet are more variable and unpredictable, and the data packet transmission is reduced. risk of information leakage during the process.

[0027] In this embodiment, the decryption key is generated by the cloud server to ensure that the decryption key matches the data packet encryption method, thereby ensuring the reliability of the receiving terminal to decrypt the encrypted data packet according to the decryption key. At the same time, the decr...

Abstract

According to the data transmission method provided by the invention, in a data packet sending process, a cloud server encrypts a data packet, and then the cloud server sends the encrypted data packetand a decryption key to a receiving terminal. According to the data transmission method provided by the invention, encryption of the data packet in the sending process is realized, compared with the existing data packet which is sent after being encrypted, the encryption process and the encryption mode of the data packet are more variable and difficult to predict, and the risk of information leakage in the data packet sending process is reduced.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method. Background technique [0002] With the rapid development of cloud computing, the security of cloud computing services has become a key factor restricting its wide application. Cloud data security can be divided into cloud storage security, cloud computing security and cloud transmission security. Both cloud storage and cloud computing occur on the cloud service provider or user end, as long as sufficient security measures are provided, its security can be fully managed and controllable; while cloud transmission occurs between the cloud service provider and the user , the attacker can destroy, tamper and forge the transmitted data through wired or air interface access, thereby destroying the confidentiality, integrity and availability of the data. Regardless of the service model provided by the cloud, data needs to be transmitted bet...
