摘要
船用网络的快速发展使信息化航海的阶段性跃进成为可能,同时对船用网络信息安全提出了新的要求。传统船用SDN传输网数据加密机制中设定的数据加密方式具有一定的局限性,导致传输后信息丢包率较高且时延较长。针对此问题设计新型船用SDN传输网数据加密机制。根据SDN传输网特征优化传统传输协议,并对其流表匹配域进行更新。采用此协议结合AES加密算法,实现对网络中数据的映射加密。至此,新型船用SDN传输网数据加密机制设计完成。构建仿真实验环节,设定仿真网络结构,采用此机制与传统机制对仿真网络信息展开加密。通过与传统机制对比可知,此机制信息传输后丢包率较低且时延较短。综上所述,新型船用SDN传输网数据加密机制对比传统机制使用性能具有一定程度的提高。
The rapid development of marine network makes it possible to make the periodical leap forward of information navigation. At the same time, it puts forward new requirements for the information security of marine network. The data encryption method set in the traditional marine SDN transmission network data encryption mechanism has certain limitations, resulting in high packet loss rate and long delay after transmission. To solve this problem, a new data encryption mechanism for marine SDN transmission network is designed. According to the characteristics of SDN transmission network, the traditional transmission protocol is optimized, and its flow table matching domain is updated. Using this protocol combined with AES encryption algorithm to realize the mapping encryption of data in the network. So far, the design of data encryption mechanism of the new marine SDN transmission network has been completed. The simulation experiment link is constructed, the simulation network structure is set, and the simulation network information is encrypted by this mechanism and the traditional mechanism. Compared with the traditional mechanism, this mechanism has lower packet loss rate and shorter delay. To sum up, the performance of the new marine SDN transmission network data encryption mechanism is improved to a certain extent compared with the traditional mechanism.
