传统的通信网络密文信息差错恢复方法未对进行密文信息特征增强,导致密文信息的恢复耗时较长,存在一定的误差。提出模糊数学的通信网络密文信息差错恢复方法。设计密文信息恢复流程,利用模糊数学理论计算密文信息增强算子,实现通信网络密文信息增强;采用压缩感知算法进行密文信息差错感知,提取时间域和空间域特征实现密文信息恢复。为了验证上述方法对通信网络密文信息差错恢复性能,设计对比实验。结果表明,研究的通信网络密文信息差错恢复方法,收敛速度较快,信息差错恢复所需时间较短,具有较低的密文信息恢复误差、稳定的均方根误差。

Generally,the traditional error recovery methods of ciphertext information in communication networks have a long recovery time and large errors owing to the lack of feature enhancement of unclassified information.In this regard,the error recovery method of ciphertext information in a communication network based on fuzzy mathematics was reported.Firstly,the recovery process of ciphertext information was designed.Secondly,according to the theory of fuzzy mathematics,the enhancement operator of ciphertext information was calculated to enhance the ciphertext information of the communication network.Then,a compressed sensing algorithm was introduced to detect the error of ciphertext information.Finally,temporal and spatial features were extracted to complete the recovery of ciphertext information.The results show that the method has fast convergence speed,short information error recovery time,low ciphertext information recovery error and stable root mean square error.
