Dynamic Encrypted Transmission of Heterogeneous Information Network Data Based on Timestamp
Targeting at the problems of heterogeneous information network,such as many types of dynamic data,large amount of data,and potential security risks in the process of data transmission,an encryption transmission algorithm based on timestamp is proposed.The DES algorithm is used to establish the network data encryption type query table,mark the key words and characters,and calculate the attribute,status,frequency and other information of the location of the key words through inverse conversion of the IP location of the initial data key,and give the corresponding encryption key according to the information parameters.On this basis,the undirected graph of heterogeneous information network is defined,the real-time dynamic characteristics of the network are described by using timestamp algorithm,the static data and dynamic data in the network are divided,the confusion matrix is established,and the encrypted transmis-sion sequence is constructed according to the moving and changing relationship of nodes with time to complete the final data encryption transmission.The experimental results show that the encryption effect of the proposed algorithm is good,it can achieve efficient encryp-tion for any type of network data,and the data transmission integrity is high.
