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 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 ...
متن کاملAn Efficient Strong Designated Verifier Signature Scheme
This paper proposes a designated verifier signature scheme based on the Schnorr signature and the Zheng signcryption schemes. One of the advantages of the new scheme compared with all previously proposed schemes is that it achieves the “strong designated verifier” property without encrypting any part of the signatures. This is because the designated verifier’s secret key is involved in the veri...
متن کاملAn 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...
