基于RSA的AIS数据传输加密系统仿真

Simulation on RSA-based AIS Data Transmission Encryption System

随着海上交通智能化的迅猛发展,船舶自动识别系统(Automatic Identification System,AIS)在海上交通运输中起到了极其重要的作用,尤其是在保证海上交通运输安全方面。但是,AIS广播系统使用过程中是开放式的,缺少必要的数据保护方案。船舶只要装有AIS接收机并处于它船AIS信号覆盖范围内,就能够接收到其他船舶和岸台播发的AIS数据信息。因此,AIS数据信息在船舶之间传输的过程中极易遭到恶意的网络攻击和数据信息的破坏。通过采用基于大数因子分解的RSA数据加密算法来提高AIS数据信息在船舶之间传输的安全性,实现了RSA加密算法的系统仿真,使得AIS数据信息在船舶之间得到了安全、高效的传输。

With the rapid development of intelligent maritime traffic,AIS(Automatic Identification System)plays an extremely important role in maritime transportation,especially in ensuring the safety of maritime transportation.However,the AIS broadcast system is open in the process of use,lacking the necessary data protection scheme.Ships can receive AIS data information broadcast by other ships and shore stations as long as equipped with AIS receivers and being within the coverage of other ships,AIS signals.Therefore,AIS data information is highly vulnerable to malicious network attacks and data information damage during the transmission process of between the ships.By using RSA data encryption algorithm based on large number factorization,the security of AIS data information transmission between ships could be improved,and the system simulation of RSA encryption algorithm is realized,making AIS data information safely and efficiently transmitted of between the ships.
