摘要 论文介绍了LHL(t,n)门限签名方案中宽带阈下信道的构造方法,研究发现该方案中存在阈下收方伪造LHL签名的缺陷,进而给出了阈下收方伪造LHL签名的计算方法。 The broadband subliminal channels in the LHL(t,n) threshold signature scheme is introduced.The inherent defect of it make the subliminal receiver has the ability to forge valid signature,and the method of forging signature is given.
