Existing aviation missile business data records and storage have the disadvantage of being tampered with easily, being traced difficultly, and other security risks. Aiming at these problems, this paper applies blockchain technology to the data recording and storage scene of aviation missile business, carries on the network structure design, uses the current mainstream encryption algorithm and the encryption technology, constructs the block chain based aviation missile service data recording storage system, and describes the system working principle and how the system protects the data. Security analysis shows that the system can effectively protect the security record and storage of data, and lays a certain foundation for further exploring the application of blockchain in military.
Missile data has the characteristics of multiple data items, large data volume and high data value, which puts forward higher requirements for data storage security. The application of block chain technology in missile business data storage can realize the safe, reliable and decentralized storage of data. The SM3 algorithm is a Hash function that supports the data structure and detects whether the data is tampered with in the blockchain. The SM3 algorithm is applied to the missile business blockchain to realize the localization of encryption, and the operation of SM3 algorithm is optimized under the condition that the missile business data contains a large number of documents, tables and pictures. Finally, the Go language was used for testing, and the results showed that the operation speed of SM3 algorithm could be improved by about 30% through optimization, and the optimization effect was obvious.
