摘要
Mark XIIA系列敌我识别系统是美军和北约部队使用的现役主战装备,广泛应用于各型导弹及反导系统之中。研究了Mark XIIA Mode 5敌我识别系统的加密方式。从加密机信号处理入手,分析了Mark XIIA Mode 5在信号波形和信号内容加密上的处理方式,主要有传输加密、询问信号加密、询问信号解密、应答信号加密、应答信号解密等步骤。通过加密指令分析,能够清楚了解Mark XIIA Mode 5敌我识别加密处理的过程。
The Mark XIIA IFF system is used by U. S. and NATO forces as the main battle equipment and widely used in various types of missiles and anti-missile systems. Mark XIIA Mode 5 IFF encryption methods are studied. From the eneryption machine＇s signal processing,the signal waveform and the content encryption modes are analyzed,including the steps of the eneryption and decryption of transporting, interviewing asking signal and answering signal. Through the analysis of encrypted instructions, the encryption process of Mark XIIA Mode 5 IFF system can be clearly understood.
