信息安全中的文本伪装新方法

Nnovel approach to text camouflage in information security

为了提高机密文本在传输过程中的安全性 ,提出了一种将文本伪装后隐蔽传输的新方法。利用小波分析的多分辨特性 ,将机密文本在小波域进行变换 ,替换为另一个不相关的公开文本 ,从而有效躲避攻击者的注意。实验结果表明 ,该方法具有隐蔽性和主观欺骗性 。

In order to improve the security of secret text during transmission processing, a novel approach to text camouflage was presented. Based on multi-resolution characteristics of wavelet analysis, another irrelevant text was substituted for secure text. Results show that the approach has good hiding feature and subjective fraudulence, and the performance of robustness behaves well even when attacked by noise.
