摘要
军事通信中,应将确保信息的绝对安全摆在首要位置。目前我军的野战通信以无线通信手段为主,通信双方的身份识别是确保战场无线通信安全的基本前提。基于现役通信装备,为提高战场通信的安全性,设计了基于DCT变换在DC分量嵌入及提取水印的方案,可为身份识别提供保障。通过Matlab仿真,与普遍现行的小波变换(DWT)技术在不可感知性、提取可信度和抗干扰性三个方面进行对比,结果表明该方法更具有优势,更适用于战场通信环境的身份识别。
It is necessary to ensure to give first priority to the information absolute security in military communication. At present,the field communication of Chinese army mainly relies on the wireless communication means,and the identity recognition of the both communication sides is the basic premise to ensure the wireless communication security of battlefield. On the basis of active-service communication equipment,a DCT based scheme of embedding watermark in DC component and extracting the watermark from the DC component is designed to improve the communication security of battlefield,which can provide the safeguard for identity recognition. With Matlab simulation,this technology is compared with prevalent discrete wavelet transform（DWT）technology in the aspects of imperceptibility,extraction credibility and anti-interference. The results show that the technology is suitable for the identity recognition in the battlefield communication environment.
