Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a data transmission method according to an embodiment of the invention.
In one embodiment, a data transmission method includes:
step S10, detecting whether a 5G transmission condition is met currently;
in this embodiment, when data transmission is required between 5G terminals, it is first required to detect whether the current 5G transmission condition is satisfied. The specific modes can be as follows: and a party (a 5G sending end or a 5G receiving end) needing data transmission informs the 5G base station in a signaling mode and verifies the secret key, if the secret key is verified successfully, further judging whether the bandwidth of the currently selected 5G base station meets the 5G transmission condition, and if so, determining that the currently selected 5G transmission condition is met. If the key verification is unsuccessful or the bandwidth of the currently selected 5G base station does not meet the 5G transmission condition, selecting a new 5G base station until the transmission condition is reached. Wherein, 5G is short for fifth generation mobile communication network, 5G terminal is terminal supporting fifth generation mobile communication network, 5G base station is public mobile communication base station providing 5G network service.
Step S20, if the 5G transmission condition is met currently, the 5G transmitting end puts the data to be transmitted into a virtual isolation area;
in this embodiment, if the 5G transmission condition is currently satisfied, the 5G transmitting end virtually isolates the data to be transmitted in the disk, i.e., places the data to be transmitted in the virtual isolation area. The safety of the data in the transmission process is ensured by utilizing the local memory and disk virtual isolation technology.
Step S30, when a transmission instruction fed back by a 5G base station is received, a read-only channel between the virtual isolation area and a 5G receiving end is established through the 5G base station;
in this embodiment, when a transmission instruction fed back by the 5G base station is received, a read-only channel between the virtual isolation area of the 5G transmitting end and the 5G receiving end is established through the 5G base station. Namely, the read-only permission of the virtual isolation area of the 5G transmitting end is opened to the 5G receiving end.
Step S40, the 5G receiving end performs information security verification on the data to be transmitted in the virtual isolation area based on the read-only channel;
in this embodiment, after the read-only channel between the virtual isolation area of the 5G transmitting end and the 5G receiving end is established, the 5G receiving end may read the data to be transmitted in the virtual isolation area of the 5G transmitting end, and perform information security verification on the data to be transmitted in the virtual isolation area.
In an alternative embodiment, the step of performing information security verification on the data to be transmitted in the virtual isolation area includes:
detecting whether malicious viruses exist in data to be transmitted in the virtual isolation area; if the data to be transmitted contains malicious viruses, the information security verification fails; and if no malicious virus exists in the data to be transmitted, the information security verification is passed.
In this embodiment, whether a malicious virus exists in the data to be transmitted in the virtual isolation area may be detected by preset virus killing software. Detection of malicious viruses by antivirus software is a well established technique at present and will not be described in detail here. If no malicious virus exists in the data to be transmitted, the information security verification passes, otherwise, if the malicious virus exists in the data to be transmitted, the information security verification fails.
Further, in consideration of that some bad illegal information may exist in addition to the possible existence of malicious viruses in the data to be transmitted, further detection of the bad illegal information is required.
In an alternative embodiment of the present invention,
if no malicious virus exists in the data to be transmitted, the step of passing the information security verification comprises the following steps:
if no malicious virus exists in the data to be transmitted, detecting whether bad information exists in the data to be transmitted; and if no bad information exists in the data to be transmitted, the information security verification is passed.
In this embodiment, if no malicious virus exists in the data to be transmitted, whether bad information exists in the data to be transmitted is detected. Specifically, whether yellow/violent characters, yellow/violent pictures and/or yellow/violent text videos exist in the data to be transmitted or not can be detected. And if the bad information does not exist in the data to be transmitted, the information security verification is passed.
Further, in an embodiment, the step of detecting whether the bad information exists in the data to be transmitted includes:
acquiring one or more sub-data included in the data to be transmitted;
detecting whether at least one piece of sub data in the one or more pieces of sub data is any one of bad text information, bad pictures and bad video files;
if at least one piece of sub data is any one of bad text information, bad picture and bad video file, the bad information exists in the data to be transmitted;
if the one or more sub data are not any one of bad text information, bad pictures and bad video files, the bad information does not exist in the data to be transmitted.
In this embodiment, the data to be transmitted may include one or more sub-data, for example, the data to be transmitted includes sub-data 1, sub-data 2, and sub-data 3. After the sub data 1, the sub data 2 and the sub data 3 are acquired, the data type of each sub data is determined according to the file name suffix of each sub data. For example, if the sub data 1 is determined to be text information according to the file name suffix of the sub data 1, detecting whether the sub data 1 is bad text information; determining that the sub data 2 is a picture according to the file name suffix of the sub data 2, and detecting whether the sub data 2 is a bad picture; and detecting whether the sub data 3 is a bad video file or not according to the file name suffix of the sub data 3.
If the sub data 1 is bad text information and/or the sub data 2 is a bad picture and/or the sub data 3 is a bad video file, determining that bad information exists in the data to be transmitted. If the sub data 1 is not the bad text information, the sub data 2 is not the bad picture and the sub data 3 is not the bad video file, determining that the bad information does not exist in the data to be transmitted.

Wherein the terminal is directly connected, namely the Device-to-Device. D2D communication technology refers to a communication manner in which two peer user nodes communicate directly. As shown in fig. 2, fig. 2 is a schematic diagram of a scenario in which data transmission is performed based on terminal through communication. The base station discovers the D2D communication equipment (a 5G transmitting end and a 5G receiving end), establishes logic connection, then controls the resource allocation of the D2D equipment, and performs resource scheduling and interference management. And the 5G sending end and the 5G receiving end are communicated through a terminal to carry out data transmission.
In a decentralized network of D2D communication subscribers, each subscriber node is capable of transmitting and receiving signals and has the function of automatic routing (forwarding messages). The participants of the network share some of the hardware resources they own, including information processing, storage, and network connection capabilities. These shared resources provide services and resources to the network that can be accessed directly by other users without going through intermediate entities. In a D2D communication network, user nodes act as both servers and clients, and users are aware of each other's presence, forming a virtual or actual community, self-organised.
In this embodiment, whether a 5G transmission condition is currently satisfied is detected; if the 5G transmission condition is met currently, the 5G transmitting end puts the data to be transmitted into the virtual isolation area; when a transmission instruction fed back by a 5G base station is received, a read-only channel between the virtual isolation area and a 5G receiving end is established through the 5G base station; the 5G receiving end performs information security verification on the data to be transmitted in the virtual isolation area based on the read-only channel; and when the information security verification is passed, transmitting the data to be transmitted to the 5G receiving end through terminal through communication. According to the embodiment, before data transmission is carried out by the two terminals based on 5G communication, information security verification is carried out on the data to be transmitted, and data transmission is carried out based on the 5G communication only after the information security verification is passed, so that poor information is prevented from being transmitted between the terminals, and the information system security of the receiving terminal is ensured.
