Problems solved by technology

However, the encryption and authentication processes in the existing communication systems are carried out separately. Since the encryption process and the authentication process occupy the transmission bandwidth of the communication system to a certain extent, the encryption and authentication processes used in the existing communication systems When data transmission is carried out in this way, the transmission bandwidth is relatively large.

Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] refer to figure 1 , figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the solution of the embodiment of the present invention.

[0057] The terminal of the embodiment of the present invention is the sending end or the receiving end of the data transmission system, and the data transmission system may be a digital communication system such as a CDRadio (symbiotic FM data broadcasting) system and an HD Radio (High-Definition Radio, high-definition radio) system.

[0058] Such as figure 1 As shown, the terminal may include: a processor 1001 , such as a CPU (Central Processing Unit, central processing unit), a communication bus 1002 , a user interface 1003 , a network interface 1004 , and a memory 1005 . Wherein, the communication bus 1002 is used to rea...

Abstract

The invention discloses a data transmission method and system and a computer readable storage medium. The data transmission method is applied to a sending end, and t. The data transmission method comprises the following steps: the sending end processes a service plaintext by adopting a one-way hash function algorithm to generate a service abstract, and asymmetrically encrypts the service abstractby adopting a first private key of the sending end to generate an abstract ciphertext; symmetrically encrypting the service plaintext is symmetrically encrypted by adopting a secret key to generate aservice ciphertext; performing asymmetric encryption is performed on the secret key by adopting a second public key of a receiving end to generate a secret key ciphertext; and sending the abstract ciphertext, the service ciphertext and the secret key ciphertext are sent to the receiving end. According to the method disclosed in the invention, the data in the communication system can be encrypted and authenticated at the same time, so thatand therefore the occupation of transmission bandwidth is reduced.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a data transmission method, system and computer-readable storage medium. Background technique [0002] With the development of digital technology and broadcasting technology, communication systems are no longer limited to traditional audio and video services, but are developing towards diversified data services. With the development of diversified data services, there are more and more security requirements for confidential data transmission, authorized reception of data, and validity identification of received data. [0003] At present, communication systems use data encryption and authentication to ensure communication security. However, the encryption and authentication processes in the existing communication systems are carried out separately. Since the encryption process and the authentication process occupy the transmission bandwidth of the communication system to ...
