摘　　要：结合船用物联网网络数据加密的特点与要求,提出船用物联网大数据加密的混合密码体制。首先,建立船用物联网大数据交互框架;接着,在框架基础上确认混合加密算法的公钥策略;完成上述计算后,对混合加密算法的离散性进行安全计算;最后,对计算所得离散椭圆曲线进行对称加密与非对称加密逻辑的对称特征识别计算,实现动态随机切换混合加密算法对称逻辑的效果,提升物联网大数据加密数据的安全性。为了验证提出加密体制的效果,通过仿真技术手段设计实验场景,对传统加密体制与设计加密体制进行安全防护性能测试,通过对比数据证明提出设计具有较强的防护性与安全性。According to the characteristics and requirements of marine Internet of things data encryption,a hybrid cipher system of big data encryption for marine Internet of things is proposed.Firstly,the big data interactive framework of marine Internet of things is established;then,the public key strategy of the hybrid encryption algorithm is confirmed on the basis of the framework;after the above calculation,the discreteness of the hybrid encryption algorithm is calculated securely;finally,the symmetric feature recognition calculation of symmetric encryption and asymmetric encryption logic is carried out for the calculated discrete elliptic curve,and the dynamic random tangent is realized.Changing the effect of symmetric logic of hybrid encryption algorithm,the security of big data encrypted data on the Internet of things is introduced.In order to verify the effect of the proposed encryption system,the experimental scene is designed by means of simulation technology,and the security protection performance of the traditional encryption system and the designed encryption system are tested.Through the comparison of the data,it is proved that the design has strong protection and security.
