Asymmetric encryption transmission method for wireless network data security
To solve the problem of long data transmission delay in wireless network,a data open privacy disclosure evaluation method based on matrix calculation is proposed.A noise free data transmission chan-nel based on wavelet transform algorithm is designed to obtain user information and calculate the risk of net-work transmission data leakage.Besides,a key generator is designed based on the typical RSA algorithm in asymmetric encryption technology,which could obtain the encryption key and decryption key related to data transmission respectively.Based on DFT-S-OFDM model,the efficient transmission and reception of wire-less network data encryption signals is completed.The experiment results show that the data encryption transmission delay of the proposed method is kept below 2 ms,the average delay is about 1.02 ms,and the data encryption transmission delay is reduced by 76.55％and 88.37％.
