Example Embodiment

[0190] Example 1

[0191] This embodiment uses intelligent sharing equipment and / or sharing big data as technical scenarios to illustrate the technical solutions of the present application. This application scenario is only an example for understanding the technical solutions of the present invention, and the present invention includes but is not limited to this. .

[0192] like image 3 As shown, the application scenario may include the following devices: node U1 (representing UE1), node N1 (representing Node1), node D (representing data source node Data source), one or more blockchains, each blockchain has It is composed of several blockchain nodes. In this embodiment, the above scenario is used as an example to illustrate the content of the invention, but the method provided in this embodiment includes but is not limited to the above scenario.

[0193] This embodiment provides a data access method, which specifically includes the following steps:

[0194] Step 301: A fir...

Example Embodiment

[0277] Embodiment 2

[0278] This embodiment provides a data transmission method, which can be used for a node that does not apply for data access for the first time, for example, a process in which the first node initiates data access to the blockchain network. This method may also be performed on the basis of Embodiment 1, that is, after the first node applies for accessing data for the first time, the first node in this embodiment initiates an access request for the same data. In addition, the method can also be executed independently, and the first node initiates a data access request to the blockchain node.

[0279] This embodiment is based on the method steps of the first node requesting access to data for the first time in the first embodiment, and describes in detail the request of the first node to access the same data.

[0280] First, according to the description of the first embodiment, the first blockchain is used to record the key information of the data. Specif...

Example Embodiment

[0340] Embodiment 3

[0341] This embodiment also provides a data transmission method, see Figure 5 , the method includes three parts of the process, namely part A, part B and part C, wherein the method in part A describes the process of the first node (U1) requesting access to the data, and the method in part B describes the second node (U2) requesting access to the data. The process, part C method describes the process of the third node (U3) requesting access to data.

[0342] Among them, these three parts of the method process can be executed independently, or combined in two, for example, part A and part B, part B and part C, or part A, part B and part C can be combined. This is not limited.

[0343] The method steps of each part of the process in this embodiment will be described and introduced below.

[0344] Part A Process

[0345] The method flow of Part A describes the process of the first node U1 requesting access to data.

[0346] Specifically, as Figure 5 s...

Abstract

The invention discloses a data transmission method and device and a network node. The method comprises: enabling a first node to obtain data information and secret key information of data recorded ona first block chain; obtaining encrypted data according to the data information, and obtaining a secret key according to the secret key information of the data; and decrypting the encrypted data by using the key to obtain data. According to the method, the characteristic of data sharing on the block chain is utilized, so that the first node of the requester can directly obtain the data informationfrom any block chain node of the block chain, the burden of repeated transmission of the data information between a core network or a plurality of routes is further reduced, and the transmission delay is reduced.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data transmission method, device and network node. Background technique [0002] In the current communication system, in order to reduce the delay for users to obtain services, a method of mobile edge computing is proposed. That is, data is stored close to users (such as base stations or routers) to provide services to users, but the provision of services or data is still subject to a monopoly third party. [0003] In addition, the basic idea of ​​Content Delivery Network (CDN) is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. By placing a layer of intelligent virtual network based on the existing Internet based on node servers placed everywhere in the network, the CDN system can real-time according to the network traffic and the c...
