Abstract

The embodiment of the invention provides a data transmission method. The method comprises the following steps: a client device and a trusted server carrying out trusted authentication and establish acovert channel; the trusted server transmitting the encrypted certificate to the client device through a concealed channel; the client device dividing the data into a data packet set, encrypting one data packet by using an encryption certificate, and transmitting the encrypted data packet to the trusted server; after receiving the encrypted data packet, the trusted server transmitting an encryption certificate to the client device through a concealed channel; the client device generating and transmitting an integrity check packet to the trusted server after transmitting the data packet set; and the trusted server receiving the integrity check packet and performing integrity check. By means of the technical scheme, multi-type, diversified and multi-mode access can be supported, safety credit granting between equipment and a platform and between platforms is increased on the basis of a hidden channel and a subpackage transmission principle, and safety encryption transmission of data is achieved.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a data transmission method and system. Background technique [0002] With the continuous growth of electric vehicle time-sharing leasing business, electric vehicle time-sharing leasing operations have been carried out in most cities across the country. In just a few years, the number of electric vehicles has reached millions of vehicles, and the number is increasing. , There are also huge problems. This is particularly prominent in terms of operational security. Data security is the key protection object. Multiple problems such as user / transaction data leakage, vehicle theft, and data tampering exist at the same time, leading to great hidden dangers in operations. Summary of the invention [0003] The purpose of the embodiments of the present invention is to provide a data transmission method and system that can reliably and completely transmit data. [0004] To achieve th...
