ID-based Restrictive Partially Blind Signatures and Applications

Authors: Xiaofeng Chen, Fangguo Zhang, Shengli Liu


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 rules. Partially
blind signatures allow a signer to explicitly include necessary
information (expiration date, collateral conditions, or whatever)
in the resulting signatures under some agreement with receiver.
Restrictive partially blind signatures incorporate the advantages
of these two blind signatures. The existing restrictive partially
blind signature scheme was constructed under certificate-based
(CA-based) public key systems. In this paper we follow Brand’s
construction to propose the first identity-based (ID-based)
restrictive blind signature scheme from bilinear pairings.
Furthermore, we first propose an ID-based restrictive partially
blind signature scheme, which is provably secure in the random
oracle model. As an application, we use the proposed signature
scheme to build an untraceable off-line electronic cash system
followed Brand’s construction.
