摘要
针对传统共享充电桩在交易过程中存在通信效率较低且节点复杂程度高的问题,文中基于超轻节点区块链技术提出了一种共享充电桩信息安全机制。该方案对区块链数据传输平台和共识机制进行了改进,通过利用分组的思想赋予节点不同的功能,在满足节点通信的基础上优化了开销。同时还对PBFT共识机制进行了优化,采用权重矩阵对节点传播路径加以管控,进一步减少了数据传输所需的时间。实验平台使用5个节点的模拟区块链架进行了多项测试。测试结果表明,所设计方法在节点数为4时的吞吐量可达1 400 tps,且传输时延、交易完成率以及CPU占用率等指标均优于对比算法,能够有效降低通信开销。
Aiming at the problems of low communication efficiency and high node complexity in the transaction process of traditional shared charging piles,this paper proposes a shared charging pile information security mechanism based on ultra light node blockchain technology.This method improves the blockchain data transmission platform and consensus mechanism,endows nodes with different functions using the idea of grouping,and optimizes the communication cost on the basis of satisfying node communication.At the same time,the PBFT consensus mechanism is improved,and the weight matrix is used to control the node propagation path,further reducing the time used for data transmission.The experimental platform uses five nodes to simulate the blockchain frame,and has carried out a number of tests at the same time.The test results show that the throughput of the method designed in this paper reaches 1400 tps when the number of points is 4,and the transmission delay,transaction completion rate,CPU utilization and other indicators are better than the comparison algorithm,which can effectively reduce the communication overhead.
