| 摘 要： | 采用传统的借助信赖者的(t,n)门限方案的思想,结合EIGamal型签名方案和(t,n)门限签名方案,提出了一种对中心隐藏个人私钥,从而限制中心权限的更安全的门限签名方案,并与原方案进行了比较,新方案不仅可以防止第3方欺骗,而且具有个人签名和集体签名的双重功能.

| Abstract: | With the concept of traditional (t,n) threshold signature with truster, a new improved (t,n) threshold signature is proposed combining EIGamal signature and (t,n) threshold signature, in which the privy key is concealed so that the truster could not play the trick. These two signatures are compared, on the base of which it is proved that the new signature can not only be used in group signature not to be deceived by the third person, but also be used in privy work. |
