雷达情报网安全传输设备的设计与实现

Design and Implementation of Security Transmission System in Radar Intelligence Network

针对雷达情报网的特点,提出了一种应用分层加密思想实现端到端安全加密传输的机制.设计基于芯片IP2022的硬件加解密设备实现加密层功能,采用级联序列加密和分组加密的技术对雷达情报报文加密,测试表明设备加密性能和处理速度达到指标要求.

In terms of the characteristics of the radar intelligence network, an end-to-end encrypted information transmission mechanism based on encryption layer is proposed in this paper. An encrypt-and-decrypt system is implemented by using the chip IP2022, and radar intelligence is encrypted by stream and block ciphering sequentially. By test it shows that the performance of the system is up to the standard. Key words： encryption layer; chaotic sequence; LFSR
