存在潜信道的数字签名算法研究

The Research of Digital Signature wi th Subliminal Channels

潜信道是在公开信道中所建立的一种实现隐蔽通信的信道。介绍了潜信道方面的基本知识,提出了存在宽带潜信道和窄带潜信道的数字签名算法,并对这两种算法的安全性作了分析。

Subliminal channel is a channel whic h is built in the public channel in ord er to realize secret communication.In this paper,we int roduce some base knowledge about subliminal channel,then we propose two digital signature schemes with broadband subliminal channel and narrow subliminal channel.Lastly,we analyze the security performance of these di gital signature schemes.
