摘　　要：针对移动网络支付过程中的安全问题,文中构建了一个基于改进DNS协议的移动网络支付安全通信协议模型。该模型采用改进的DNS协议,通过引入区块链技术,使每个顶级域名都成为了一个自主根,再由自主根组成根联盟,从而共同参与每个数据节点的发布和管理。利用这种去中心化的思想,有效提高了移动网络支付的安全性。特别是对PBFT共识算法进行的改进,通过主动获取节点网络中所有节点的视图以及最新的区块高度等信息,恢复了网络运行过程中导致的部分节点执行落后问题,进一步保证了数据的一致性和安全性。In view of the security problems in the process of mobile network payment,this study constructs a mobile network payment security communication protocol model based on the improved DNS protocol.The improved DNS protocol is adopted in the model.By introducing blockchain technology,each top-level domain name becomes an autonomous root,and then the autonomous root forms a root alliance,so as to participate in the publishing and management of each data node.Using this idea of decentralization,the security of mobile network payment is effectively improved.In particular,the PBFT consensus algorithm is improved by actively obtaining the views of all nodes in the node network and the latest block height and other information,so as to restore the backward execution of some nodes caused by the operation of the network,and further ensures the consistency and security of data.
