Improved Dynamic Threshold Signature Scheme
Jianzhong Zhang · Jisuanji gongcheng · 2007
Contraposed the insecurity of WLC-digital signature scheme,this paper makes some improvement.The main merits are that a valid signature is generated only by the designated clerk participating together: if some new members join the group or some members are deleted left the group,the system parameters and the key pairs of other members remain the same,and that an individual could sign messages for different organizations at the same time with the same secret key pair.
