Abstract: To enjoy the property of error tolerance in the biometric identities extraction, the fuzzy identitybased signature has been initialized to issue a signature on behalf of a descriptive attributes set ω instead of a single string. Any attributes set ω′ can be used to verify the validity of the signature in case the distance between ω and ω′ is less than a pre-defined threshold. Recently, Wang re-formalized the notion of fuzzy identitybased signature and proposed a concrete pairing-based construction along with the efficiency analysis and formal security proof. Unfortunately, by giving concrete attack, we indicate that Wang's scheme is not secure against forgery attack. We also present an improved scheme to prevent this attack. © 2014 Science China Press and Springer-Verlag Berlin Heidelberg.
