摘要

本文分析了阈下信道技术在数字签名中的应用

并以一种有序多重数字签名方案为例

对其中存在的宽带和窄带阈下信道进行了具体分析.提出了一种有序多重签名体制下的窄带阈下信道通信方案

通过实时性测试确定阈下信息位数

从而满足了传输信息容量与实时性的要求.

Abstract

The subliminal channel is a covert communication channel constructed in public corresporiVence pattern.As a land of the modem information hiding technology

it is used to transmit the secret infomation.The subliminal channel in general) gamal signature is analyzed.And the wideband and narrowband subliminal charurel in the ordinal digital multi-signature is discussed.A scheme of rramowband subliminal channel in the ordinal digital multi-sigttatune is given and the bit rate of the sent rtressage is confimed by a real-time test so that the capacity and real-time request of the narrowband subliminal channel can be satisfied.
