A (t, n) threshold signature scheme allows t or more group members to generate signatures on behalf of a group with n members, while any t−1 or less members cannot do the same th...
Directed signature scheme allows only a designated verifier to check the validity of the signature issued to him; and at the time of trouble or if necessary, any third party can v...

A proxy blind signature scheme is a digital signature scheme which combines the properties of proxy signature and blind signature schemes. Recently, Tan et al. proposed two proxy ...
Several new group signature schemes have been proposed in recent years. In addition, several applications for group signatures (including electronic cash) have been suggested. A ne...
The concept of public-key cryptography was invented in 1976 by Diffie and Hellman [DH]. The following year, Rivest, Shamir and Adleman provided an implementation of this idea [RSA]...
