【摘要】 牛顿信道在数字签名的安全性和阈下信道的带宽之间找到了一个折衷点,但我们研究发现了牛顿信道的陷门及其存在的条件,并且提出了避免满足陷门条件的签名参数计算方法,以使阈下收方无能力利用牛顿信道来伪造签名。更多还原

【Abstract】 The Newton channel give a compromise between the security of a digital signature and the bandwidth of the subliminal channel. But now the trapdoor of the Newton channel and its existing conditions are investigated. Then the algorithm of the parameters that to avoid the trapdoor conditions is presented. Finally the subliminal receiver will have no ability to forge the digital signature by Newton channel.更多还原
