针对当前船舶网络信息用户访问传输系统中存在的精度低、速度慢,安全性能较差等问题进行深入研究,为保证舰船网络用户通信访问的安全性,提出基于统计学的船舶信息传输网络用户访问安全性算法。通过对船舶用户网络信息访问和传输安全的机密性、完整性、可用性向量进行分析,构建了网络信息传输安全评估体系。由此生成网络信息安全控制模型并对该模型进行安全性评估,以便实现多用户之间的网络信息访问传输资源共享安全控制,最终实现基于统计学的船舶信息传输网络的安全访问算法。最后对上述设计的有效性进行实验,实验结果表明,基于统计学的船舶信息传输网络用户访问安全性研究能够有效提高舰船网络访问控制的安全性,具有精准度高、评估速度快、安全性强等优势,对日常的大型船舶移动网络信息传输安全防护起到指导作用。

Aiming at the problems of low precision, slow speed and poor security in the current ship network information user access transmission system, this paper makes investigation and analysis. In order to ensure the security of ship network users' communication access, a statistical-based security algorithm for ship information transmission network users' access is proposed. By analyzing the confidentiality, integrity and availability vector of ship users' network information access and transmission security, the network information transmission security evaluation system is constructed. Thereby generate a network information security control model and carrying out security evaluation on that model, calculate the relationship between the maximum probability of access users and the number of application of the ship information transmission network by using statistics, realizing the shared security control of network information access transmission resources among multiple users, and finally realizing the security access algorithm of the ship information transmission network based on statistics. The effectiveness of the above design was tested, the experimental results show that the ship information transmission network user access security research based on statistics can effectively improve the security of ship network access control,with high accuracy, fast evaluation speed, strong security and other advantages, to daily large-scale mobile network information transmission security protection plays a guiding role.
