摘要
数据安全是保证用户访问安全的基础,为了提升控制性能与数据安全性,提出复杂网络环境下链上数据安全访问控制方法。基于复杂网络环境的分析结果提取链路数据特征分量,使用分布式融合方法建立网络链上数据存储的决策树结构模型。以提取的链路数据特征分量为基础,计算网络链上访问数据发送速率、传输往返时间以及丢包率等控制参数,通过丢包率平滑器处理链上数据,结合链上数据平滑处理结果,修正网络访问数据包速率变化参数,完成数据安全访问控制。实验结果表明,使用上述控制方法开展链上数据安全访问控制时,控制性能和安全性能均得到了明显提升。
Data security is the basis for ensuring user access security.In order to improve control performance and data security,this paper presented a method to control the on-chain data security access in a complex network environment.Based on the analysis result of the complex network environment,the feature components of link data were extracted,and then a decision tree model of the data storage on the network chain was built by distributed fusion.Based on the extracted feature components of link data,the control parameters such as the data transmission rate,round-trip time and packet loss rate on the network chain were calculated.Moreover,the on-chain data was processed with a packet loss rate smoother.Combined with the data smoothing results,the rate change parameters of the network access packet were modified.Finally,data security access control was completed.Experimental results show that the control performance and safety performance have been significantly improved by the proposed method.
