The lack of data link model in traditional encryption technology of electronic communication data link leads to low encryption efficiency of data link and is vulnerable to differential attack and information entropy attack.Therefore,this paper proposes a data link encryption simulation of electronic communication based on spatial sparse coding.Spatial sparse coding was used to build the data link model of electronic communication.Based on the sparsity of the data link,the encryption key generation process of the data link was thoroughly designed.The simulation encryption of data link was completed on the professional TOSSIM simulation platform of data link encryption.The operation time function,the spatial position of data link,the ciphertext pixel value and the calculation formula of information entropy were determined.The three groups of data link encryption technology,the encryption execution efficiency of electronic communication data link,and the resistance effect to differential attack and information entropy attack were compared.The results show that the encryption simulation technology has a short encryption time,high execution efficiency,and can effectively resist differential attacks and information entropy attacks.
