Abstract

The invention discloses a data sending method based on blockchain, and the method comprises the steps that a cloud server acquires source data and sets the source data as a tree structure, wherein thesource data is acquired by a plurality of edge nodes and is transmitted to the cloud server; the cloud server sets a blockchain channel, inserts block data in the blockchain into child nodes in the tree structure, and defines the source data into which the block data is inserted as block source data, wherein the block data is of a chain storage type and comprises a block head and a block body; after receiving a data access request, the cloud server performs frequency hopping conversion on block data in the block source data based on a port frequency hopping strategy to generate a pseudo-random port, wherein the port number of the pseudo-random port changes along with the time period; and the cloud server sends the block source data through the pseudo-random port.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a blockchain-based data sending method. Background technique [0002] In the information society, data security is becoming more and more important. In traditional data sending and receiving systems, it is necessary to send data through fixed ports, such as HTTP, FTP and other ports, which are used to send data fixedly. [0003] However, in the prior art, there are often hackers or virus attacks, such as DOS attacks, which directly and illegally capture the data output by the port, which will make the current data security defense very passive and low in security. Contents of the invention [0004] An embodiment of the present invention provides a blockchain-based data sending method, which is used to solve the problem of low data defense security in the prior art. [0005] The embodiment of the present invention provides a blockchain-based data transmission met...
