A Novel Multi-factor ID-based Designated Verifier Signature scheme
In a classic digital signature scheme, the global community is capable of verifying a signature. In a designated verifier scheme (DVS), only the designated verifier has this capability. In a classic DVS scheme the signer themselves “designates” the entity that will have the capability of verifying their signature. In a pure identity-based signature scheme a Trusted Authority is introduced, and ...
متن کاملIdentity Based Strong Designated Verifier Parallel Multi-Proxy Signature Scheme
This paper presents a new identity based strong designated verifier parallel multiproxy signature scheme. Multi-Proxy signatures allow the original signer to delegate his signing power to a group of proxy signers. In our scheme, the designated verifier can only validate proxy signatures created by a group of proxy signer.
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 کاملDesignated Verifier Threshold Proxy Signature Scheme without Random Oracles
In a (t, n) designated verifier threshold proxy signature scheme, an original signer can delegate his/her signing power to n proxy signers such that any t or more out of n proxy signers can sign messages on behalf of the original signer but t− 1 or less of the proxy signers cannot generate a valid proxy signature. Of course, the signature is issued for a designated receiver and therefore only t...
متن کاملAttacks on One Designated Verifier Proxy Signature Scheme
In a designated verifier proxy signature scheme, there are three participants, namely, the original signer, the proxy signer, and the designated verifier. The original signer delegates his or her signing right to the proxy signer, then the proxy signer can generate valid signature on behalf of the original signer. But only the designated verifier can verify the proxy signature. Several designat...
