Verifier-Key-Flexible Universal Designated-Verifier Signatures
Universal Designated-Verifier Signatures (UDVS) are proposed to protect the privacy of a signature holder. Since UDVS schemes reduce to standard signatures when no verifier designation is performed, from the perspective of a signer, it is natural to ask if a UDVS can be constructed from widely used standardized-signatures so that the existing public key infrastructures for these schemes can be ...
متن کاملUniversal Designated-Verifier Signatures
Motivated by privacy issues associated with dissemination of signed digital certificates, we definea new type of signature scheme called a ‘Universal Designated-Verifier Signature’ (UDVS). A UDVSscheme can function as a standard publicly-verifiable digital signature but has additional functional-ity which allows any holder of a signature (not necessarily the signer) to designate the...
متن کاملNew Extensions of Pairing-Based Signatures into Universal (Multi) Designated Verifier Signatures
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 verifiable digital signatures but have an additional functionality which allows any holder of a signature to designate the signature to any desired verifier. This designated verifier can check that the message was indee...
متن کاملAn improvement in strong designated verifier signatures
Designated verifier signature schemes are applied in situations such as electronic voting and electronic auctions. Signature recipients can ascertain the contents of the document, but cannot verify the identity of the signer to a third party. This study reviewed the protocols of past researches and analyzed whether these protocols would disclose signer identities under various types of attacks....
متن کاملOn Delegatability of Four Designated Verifier Signatures
In a paper recently published in ICALP 2005, Lipmaa, Wang and Bao identified a new essential security property, non-delegatability, of designated verifier signature (DVS) schemes. Briefly, in a non-delegatable DVS scheme, neither a signer nor a designated verifier can delegate the signing rights to any third party T without revealing their secret keys. We show that the Susilo-ZhangMu identity-b...
