specific Embodiment approach

[0094] The content of the block needs to be redefined. In addition to generating the necessary basic content of the blockchain, such as index, timestamp, hash value of the previous block, etc., the block also needs to add the following fields:

[0095] DataType: block type;

[0096] PublicKey: public key value;

[0097] Sender: sender;

[0098] Receiver: receiver;

[0099] HashCode: hash verification code;

[0100] Status: status bit;

[0101] The complete implementation process is as follows image 3 As shown, it is divided into four stages, and the steps are as follows:

[0102] Step 1: Public key synchronization phase. After the nodes on the blockchain B are started, the data sending and receiving program uses an asymmetric encryption algorithm (the present invention uses the RSA encryption algorithm) to generate a public key and a private key, and the private key is stored in the local database, and then the data sending and receiving program creates a new area Block,...

Abstract

The invention provides an auxiliary data cross-network convergence method and system based on a block chain technology. The method comprises the following steps of a data distributed storage and calling step, reading and writing distributed management structured data and unstructured data according to HBase and HDFS components, a data security confluence step, encrypting the data by using an asymmetric encryption algorithm, a block chain operation and synchronization step, performing cross-network synchronization of the data by using the block chain, and a cross-network data transmission step,configuring a route for opening a specified port, and carrying out TCP / IP communication. The method is advantaged in that data transmission is not interrupted, data cannot be stolen, the data is complete and not lost, and cross-network transmission is convenient and safe.

Description

technical field [0001] The present invention relates to the technical field of cross-network transfer of data, in particular to a method and system for assisting cross-network transfer of data based on blockchain technology. In particular, it relates to an anti-strike military data collection method and system based on distributed remote cross-network exchange. Background technique [0002] With the development of military science and technology, there are more and more test data of weapons and equipment, and the data interaction of each test area is becoming more and more frequent. In the test area, the test network is often isolated from the internal network, and the data can only be transmitted by copying data or connecting to a switch. In the process of interaction between the test network and the intranet, once security issues such as data tampering and leakage occur, the business development will be affected in the slightest, and core information will be leaked in the ...
