【摘要】 门限共享验证签名提高了签名验证的可信度,该文提出了一种无可信中心门限共享验证签名方案。该方案中,任意t个验证者合作能够验证签名的有效性,少于t个不能验证签名。与已有方案相比,该方案无需可信中心的参与,避免了"权威欺骗";在共享验证签名阶段不需要事先确定验证者,提高了方案的灵活性。更多还原

【Abstract】 Threshold shared verification signature improves the credibility of the signature verification.A threshold shared verification signature scheme is proposed without a trusted party,in which any t verifiers can cooperate to verify the validness of the signature,and any fewer than t verifiers can do nothing.Compared with the existing schemes,the scheme has no trusted party and can avoid the authority deception.Besides,it does not need to determine verifiers at first in the stage of shared verification signature, which enhances the flexibility of the scheme.更多还原
