摘要
随着计算机和网络通信技术的发展，数字签名技术得到了广泛的应用．文中以美国数字签名标准ＤＳＳ／ＤＳＡ为基础，设计了群体数字签名，数字签名的（ｔ，ｎ）共享认证以及远程口令认证３种应用方案．群体数字允许多人分别签署同一份文件，然后所有的个体签名组成同一份群体签名．数字签名的（ｔ，ｎ）共享认证是由ｎ个认证者中的任何ｔ个来共同验证一份签名．远程口令认证将口令验证与数字签名ＤＳＡ方案紧密结合，给口令验证带来了新的思路．
With the development of the technology of computer and network communication, digital signature schemes have got extensive application. In the paper here, three applied schemes based on USA's digital signature standard DSS/DSA are presented. They include multisignature scheme, digital signature scheme with (t,n) shared verification and remote password authentication scheme. The multisignature scheme allows multiple signers to sign the same message separately and all individual signatures can be combined into a multisignature. The digital signature scheme with (t,n) shared verification lets any t verifiers in n collaborate to verify a signature. The remote password authentication scheme combines the password authentication with digital signature DSA closely, which provides a new way of thinking for password authentication.
