One of the important applications of digital signature is anonymous credential or pseudonym system. In these scenarios, it is essential that the identity of the signer is kept secr...
The identity-based signature (IBS) scheme proposed by Sakai, Ohgishi and Kasahara in 2000, which we refer to as the SOK-IBS scheme, is the first pairing-based IBS scheme. Though ...
The concept of universal designated verifier signatures was introduced by Steinfeld, Bull, Wang and Pieprzyk at Asiacrypt 2003. These signatures can be used as standard publicly ve...
We investigate the possibility to prove security of the well-known blind signature schemes by Chaum, and by Pointcheval and Stern in the standard model, i.e., without random oracle...
We describe two new paradigms on how to obtain ordinary signatures that are secure against existential forgery under adaptively chosen message attacks (fully-secure, in short), fro...
