基于改进PBFT共识算法的舰艇编队数据安全共享研究

Research on Data Security Sharing of Ship Formation Based on Improved PBFT Consensus Algorithm

针对分布式舰艇编队数据的完整性和安全性问题,论文深入研究并设计了基于改进PBFT共识算法的舰艇编队数据安全共享模型,从战场生存性、高可用性、高吞吐低延迟等方面满足舰艇编队数据安全共享需求。首先基于该模型构建了双层联盟链体系,加强高层级对数据的掌控权;同时改进了实用拜占庭共识机制,提高数据吞吐量和区块确认速度。实验分析表明,该模型提高了海上共识效率,为构建基于改进PBFT共识算法的舰艇编队数据应用系统提供了技术支撑。

Aiming at the integrity and security problems of the distributed ship formation data,this paper deeply studies and designs the data security sharing model of the fleet based on the improved PBFT consensus algorithm,which meets the data security sharing requirements of the fleet from the aspects of battlefield survivability,high availability,high throughput and low latency.First,based on the model,a two-layer alliance chain system is constructed to strengthen the control of high-level data.At the same time,the practical Byzantine consensus mechanism is improved to improve data throughput and block confirmation speed.The ex⁃perimental analysis shows that the model improves the efficiency of maritime consensus and provides technical support for building ship formation data application system based on the improved PBFT consensus algorithm.
