海上通信网络拟态防御数据自动加密方法

Automatic encryption method of mimicry defense data in maritime communication network

常规的海上通信网络加密方法,所设置的加密层偏少,导致拟态防御的保密效果不佳,为此研究海上通信网络拟态防御数据的自动加密方法。该方法利用混沌函数的扩张性、重叠折返性特点,对网络中的关键节点设置3层加密。根据每道加密层功能的不同,使用变换矩阵控制拟态防御数据的活动行为。根据海上通信网络结构,依据椭圆曲线的线性映射关系,建立可识别的网络密钥。实验结果表明,与常规加密方法相比,所提出的方法所设置的加密层级别更高,可以有效拦截访问对象的访问行为。

The conventional encryption method of maritime communication network has less encryption layer,which leads to poor security effect of mimicry defense.Therefore,the automatic encryption method of mimicry defense data in maritime communication network is studied.In this method,three layers of encryption are used to encrypt the key nodes in the network.According to the function of each encryption layer,the transformation matrix is used to control the behavior of mimicry defense data.According to the structure of maritime communication network and the linear mapping relation of elliptic curve,the identifiable network key is established.Experimental results show that compared with the conventional encryption method,the proposed encryption layer is higher and can effectively intercept the access behavior of the access object.It can be seen that this encryption method can better guarantee the use of maritime communication network security.
