1 引言雷卡通信保密有限公司生产的MA4224语音加密是一完全兼容的系列化机器的基础,该系列各机器均采用同一加密技术。时域置乱器是该机采用的基本技术。即:声音信号在时域内重新排列。重新排列受控于一复杂的密钥发生器,以确保语言信号的高度保密性。该系列机器包括:MA4224,MA4225,MA4226,MA4227,MA4296/7以及MA4400,现简介如下:
1 INTRODUCTION MA4224 Voice Encryption, manufactured by Leica Communication Security Ltd., is the foundation of a fully compatible series of machines that use the same encryption technology. Time-domain scrambler is the aircraft using the basic technology. That is, the sound signal is rearranged in the time domain. Rearrange controlled by a complex key generator to ensure the high degree of confidentiality of the language signal. The series of machines include: MA4224, MA4225, MA4226, MA4227, MA4296 / 7 and MA4400, are as follows:
