信道编码和信息加密的计算机实现

COMPUTER IMPLEMENTED COMMUNICATION CHANNEL ENCODING AND INFORMATION ENCIPHERMENT

讨论了利用微机实现信道编码和信息加密的一种通用编程方法，给出了快速产生ＣＲＣ码和加密密钥的计算框图．该方法已在某机载雷达微机数传系统中成功应用，并取代了原有的硬件编码／译码器．

A general approach to accomplish communication channel encoding and infomationencipherment by using microcomputer was discussed.The fast algorithm to generate cyclic redundancycheck code and encipherment key was also presented,which has been successfully used to replacehardware encoder/decoder of an aircraft carrying radar data transmission system.
