Communication method and communication platform based on block chain

Abstract

The invention provides a communication method and a communication platform based on a block chain. The method comprises the steps that military data serves as transaction information to be stored in distributed nodes of a block chain network in a block mode, and each block comprises a block head and a block body; in the data transmission process, each distributed node verifies the legality of thedata in a digital signature mode, and the block chain storage process calculates the HASH value through the SM3 cryptographic algorithm. According to the invention, the communication is safer, more reliable, more flexible and more intelligent.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a communication method and communication platform based on blockchain. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. Blockchain has many unique features and advantages, such as decentralization, immutability and unforgeability, verifiability and anonymity, etc. [0003] The existing military communication technology mainly relies on radio communication, but radio signals are easily intercepted, direction-finding and jammed by the enemy, so in practical application, measures must be taken from organ...

AI Technical Summary

Problems solved by technology

[0004] Military data is of great significance to combat command, but data storage is often concentrated in one or a few servers. Even with disaster recovery processing, the probability of single point failure is still relatively high

In addition, the connection between servers in the existing data storage mode is not strong, and the ability in data synchronization and data verification is not outstanding

[0005] Due to the lack of protection for historical data, the information stored according to the existing data storage method faces the risk of being tampered with. The enemy's hacker intrusion into military communication and control systems may tamper with important combat data. mistake, even misjudgment

Once the centralized storage is damaged by the enemy, the data loss will be immeasurable

[0006] In summary, the current limitations of military communications mainly include: the encryption mode is still encrypted using traditional encryption algorithms, which requires extremely high security for key storage, but there is always a risk of being deciphered technically; blockchain technology The encryption algorithms used in the military are all developed by foreign institutions, which is not conducive to the security of military information; the existing data among various departments is not circulated, and data sharing cannot be achieved, which is not conducive to the formulation of accurate strategic guidelines and overall planning
