Research on Trusted Data Sharing Method for Multi-party Edge Terminals

In recent years, Internet of Things technology (IoT) has developed rapidly and is widely used in various fields including military. The modern warfare has a new operational style of precision strike and targeted killing, among which is supported by IoT. However, during such operations, communication is not disrupted and data transmission and distribution are carried out through a centralized mode. While warfare environments are often communication constrained, with central servers facing disconnection or attack. In this study, we develop a multi-party edge terminal data sharing scheme based on blockchain technology, which improves the security and robustness of data sharing. What's more, the paper proposes a double chain storage mechanism, which improves the data sharing efficiency to a certain extent. In this paper, the proposed scheme is applied to a certain scenario for the simulation experiment. The experimental results show that the scheme can effectively support data sharing and provide a basis for the construction of reconnaissance and strike integration system.
