Identity 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 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 کاملA non-delegatable identity-based strong designated verifier signature scheme
A non-delegatable identity-based strong designated verifier signature scheme Bin Wang Information Engineering College of Yangzhou University Yangzhou City, Jiangsu Province, 225009, P.R.China E-mail:[email protected] Abstract: In a strong designated verifier signature scheme, no third party can verify the validity of a signature. On the other hand, non-delegatability, proposed by Lipmaa, Wang an...
متن کاملIdentity-based strong designated verifier signature revisited
Designated verifier signature (DVS) allows the signer to persuade a verifier the validity of a statement but prevent the verifier from transferring the conviction. Strong designated verifier signature (SDVS) is a variant of DVS, which only allows the verifier to privately check the validity of the signer’s signature. In this work we observe that the unforgeability model considered in the existi...
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...
