Unforgeability and blindness are two important properties of blind signature. The latter means that after interacting with various users, the signer is unable to link a valid messa...
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 ...
Restrictive blind signatures allow a recipient to receive a blind signature on a message not known to the signer but the choice of message is restricted and must conform to certain...
Partially blind signature schemes are an extension of blind signature schemes that allow a signer to explicitly include necessary information (expiration date, collateral condition...
In 2003, Hwang et al. proposed a new blind signature based on the RSA cryptosystem by employing Extended Euclidean algorithm. They claimed that the proposed scheme was untraceable...
