摘要
NSS是2001年提出的一个新的签名体制.文章首次给出了封闭潜信道的强和弱方法的定义,强方法可以完全阻止潜信息的发送,而弱方法只能以某个概率防止潜信息的传送.随后在NSS数字签名体制中建立了一个潜信道,并给出了封闭它的弱方法.
Two subliminal-free methods named weak (strong) subliminal-free have been proposed in this paper for the first time. The first method can only free the subliminal information on some probability, and the second can free all . Moreover, we have embedded a subliminal channel in NSS system, and also give its subliminalfree method . The NSS is a new digital signature scheme introduced in 2001. The paper is also the first one on the construction of subliminal channel in NSS.
