On Designated Verifier Signature Schemes
Designated verifier signature schemes allow a signer to convince only the designated verifier that a signed message is authentic. We define attack models on the unforgeability property of such schemes and analyze relationships among the models. We show that the no-message model, where an adversary is given only public keys, is equivalent to the model, where an adversary has also oracle access t...
متن کاملEfficient Designated Verifier Signature Schemes
This paper proposes a designated verifier signature based on the Schnorr signature scheme. One of the advantages of the new scheme compared with the one proposed by Jakobsson, Sako and Impagliazzo is that not only the designated verifier (Bob) cannot convince a third party (Cindy) that a signature is originated by a given signer (Alice), but also nobody else other than Bob can even check the va...
متن کاملDesignated-Verifier Proxy Signature Schemes
In a proxy signature scheme, a user delegates his/her signing capability to another user in such a way that the latter can sign messages on behalf of the former. In this paper, we first propose a provably secure proxy signature scheme, which is based on a two-party Schnorr signature scheme. Then, we extend this basic scheme into designated-verifier proxy signatures (DVPS). More specifically, we...
متن کاملUniversal Designated-verifier Signature with Aggregation Universal Designated-verifier Signature with Aggregation
There is a signature scheme which can aggregate two or more persons’ signatures to one, called an aggregate signature. In this paper, we propose a scheme of an aggregate signature which has additional functionality allowing any holder of a signature to designate the signature to any desired designated-verifier. By this functionality, no one other than the designated-verifier can verify the sign...
متن کاملIdentity Based Strong Designated Verifier Signature Scheme
Identity based cryptosystem simplifies the key management and revocation problem. Here we propose an Identity Based Strong Designated Verifier Signature (IBSDVS) scheme using bilinear pairings. The Designated Verifier Signature scheme described in [10] is identity based but it suffers from the deligatability as pointed out in [4]. We analyse the security of the scheme and show that the problem ...
