摘要
针对网络数据加密过程未对其进行分组,导致加密数据易出现泄密现象,提出了一种基于分组密码的网络数据保形加密数学模型,分析分组密码内的混乱规则与扩散规则,进而得到两种规则的优缺点,将两种规则作为密码系统,构建两层前馈网络的分组密码定位模型,通过上述模型对网络数据进行分组加密,分析该模型可以呈现的三种模式的特点,即简单单机模式、ETL工具模式、Spark并行模式。上述模型利用加密算法的特性进行融合,同时自动切换各模式类型来提升分组密码定位模型计算速度,结果提交至分布式计算机平台,完成对网络数据的保形加密。仿真结果证明,所提方法能够有效的对网络数据进行有效的分组加密处理,同时加密之后的网络数据与源数据未出现误差。
In this article,a mathematical model for conformal encryption of network data based on block ciphers was designed.The chaotic rule and diffusion rule in the block cipher were analyzed,and then the advantages and disadvantages of rules were obtained.The two rules constituted a cryptosystem.A block cipher positioning model of two-layer feedforward network was built.Based on this model,the network data was encrypted group by group.The characteristics of three modes were analyzed,including simple standalone mode,ETL tool mode and Spark parallel mode.The model used the characteristics of encryption algorithm for fusion,and automatically switched the type to improve the computing speed of the block cipher positioning model.The results were submitted to the distributed computer platform.Finally,the conformal encryption of network data was completed.Simulation results prove that the proposed method can effectively perform the effective block encryption on the network data.Meanwhile,there is no error between the encrypted network data and the source data.
