An efficient certificateless designated verifier signature scheme
To solve the key escrow problem in identity-based cryptosystem, Al-Riyami et al. introduced the CertificateLess Public Key Cryptography (CL-PKC). As an important cryptographic primitive, CertificateLess Designated Verifier Signature (CLDVS) scheme was studied widely. Following Al-Riyami et al. work, many certificateless Designated Verifier Signature (DVS) schemes using bilinear pairings have be...
متن کاملA Certificateless Strong Designated Verifier Signature Scheme with Non-delegatability
The designated verifier signature only enables the designated verifier to check the correctness of the signature, while any third party can not verify whether this signature is valid or not. Most of the previous designated verifier signature schemes depend on certificate-based cryptography or identity-based cryptography, while little attention has been paid to the certificateless designated ver...
متن کاملOn 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...
