基于时间戳的异质信息网络数据动态加密传输

Dynamic Encrypted Transmission of Heterogeneous Information Network Data Based on Timestamp

针对异质信息网络动态数据特征种类多、数据量大,在数据传输过程中易出现安全隐患等问题,提出一种基于时间戳的加密传输算法。采用DES算法建立网络数据加密种类查询表,标记关键字词字符,通过逆转换初始数据关键词的IP位置,计算得到关键词所处位置的属性、状态以及频率等信息,按照信息参数给出对应加密密钥。在此基础上,定义异质信息网络无向图,采用时间戳算法描述网络实时动态特性,划分网络中静态数据与动态数据,建立混淆矩阵,按照节点跟随时间的游走变化关系构建加密传输序列,完成最终数据加密传输。实验结果证明,所提算法的加密效果好,对任何类型的网络数据均能实现高效加密,且数据传输完整性较高。

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 transmission 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 encryption for any type of network data,and the data transmission integrity is high.
