Research on Application of Missile Blockchain Based on Nation Secret Algorithm

Abstract

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.
