摘要
1994年Chaum首次引进证实数字签名的概念,不同于传统的数字签名,只有在半可信指定证实者的帮助下,证实签名的有效性才能得到验证.在此对一个门限证实签名方案进行了分析,指出其安全缺陷的同时,提出了新的(t,n)门限证实数字签名方案.
In 1994 Chaum first introduced the conception of designed eonfirmer signature. Unlike an ordinary digital signature that can be verified by anyone who has access to the public verifying key of the signer, a designated confirmer signature can only be verified by engaging in a-usually interactive-protocol with some help of a semi-trusted designated confirmer. In this paper, we propose a new （t,n） threshold and confirmer signature.
