摘要
考虑到舰船在海上航行过程中通信网络的不稳定性会影响通信数据的加密传输效果,为此提出舰船航行通信数据加密传输方法研究。在舰船航行通信数据传输过程中,将通信数据定义为字节集合,利用私密密钥对通信数据进行加密。构建通信数据的密钥矩阵,引入椭圆方程曲线的加密理论,对通信数据的密钥矢量进行加密,生成舰船航行通信数据密钥。利用Logistic映射原理,得到舰船航行通信数据加密传输的编码散列值,恢复通信数据的编码矢量。根据数据编码矢量分布情况,绘制密钥排列图,实现舰船航行通信数据的加密传输。仿真结果表明,提出的通信数据加密传输方法可以减少密钥数量,并在短时间内完成通信数据的传输。
Considering that the instability of communication network will affect the encrypted transmission effect of communication data in the process of ship navigation,this paper proposes the encrypted transmission method of ship navigation communication data.In the process of ship navigation communication data transmission,the communication data is defined as a byte set,and the private key is used to encrypt the communication data.The key matrix of communication data is constructed,and the encryption theory of elliptic equation curve is introduced to encrypt the key vector of communication data to generate the key of ship navigation communication data.By using logistic mapping principle,the coding hash value of ship navigation communication data encryption transmission is obtained,and the coding vector of communication data is recovered.According to the distribution of data coding vector,the key arrangement diagram is drawn to realize the encrypted transmission of ship navigation communication data.Simulation results show that the proposed encryption transmission method can reduce the number of keys and complete the transmission of communication data in a short time.
