大数据环境下船员信息加密保护方法分析

Analysis of seafarer information encryption and protection method in large data environment

传统船员信息加密保护方法比较单一,着重点仅限于人员信息数据存储状态下的加密计算,无法对大数据环境下人员信息数据交互前与交互中进行加密保护。针对问题产生根源,提出数据环境下船员信息加密保护方法。首先通过引入展开基于椭圆曲线的传输加密算法,对信息私钥数据进行重新计算,使其具有交互保护的特性;其次,通过引入同态加密频码保护编码算法对人员信息数据进行大数据交互保护计算,完成数据交互中的安全保护处理;最后,通过仿真对比实验证明提出的大数据环境下船员信息加密保护方法,在解决数据安全保护上具有显著的效果,并且效果稳定。

The traditional methods of crew information encryption and protection are relatively simple,and the emphasis is limited to the encryption calculation in the storage state of crew information data.It is impossible to encrypt and protect personnel information and data before they interact in large data environment.Aiming at the root cause of the problem,a method of crew information encryption and protection in data environment is proposed.Firstly,by introducing the transmission encryption algorithm based on elliptic curve,the information private key data is recalculated to make it have the characteristics of interactive protection;secondly,by introducing the homomorphic encrypted frequency code protection coding algorithm to calculate the large data interactive protection of personnel information data,the security protection processing in data interaction is completed;finally,the proposed method is proved by simulation and comparison experiments.The method of crew information encryption and protection in large data environment has remarkable effect in solving data security protection,and the effect is stable.
