On the Security of a Certificateless Strong Designated Verifier Signature Scheme
Certificateless cryptography Cryptanalysis Designated verifier signature
2018/11/8
Recently, Chen et al. proposed the first non-delegatable certificateless strong designated verifier signature scheme and claimed that their scheme achieves all security requirements. However, in this ...
Strong designated verifier signature scheme: new definition and construction
Undeniable signature Designation of verifiers Discrete logarithm Random oracle model
2010/9/21
Recently, several strong designated verifier signature schemes have been proposed in the literature. In this paper, we first point out that such so-called strong designated verifier signature scheme i...

Designated verifier signature (DVS) is a cryptographic primitive that allows a signer to convince
a verifier the validity of a statement in a way that the verifier is unable to transfer the convictio...

A non-delegatable identity-based strong designated verifier signature scheme
Strong designated verifier signature Non-delegatability Bilinear pairing
2009/6/10
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 and
Bao, is another stronger ...
Attack on Kang et al.’s Identity-Based Strong Designated Verifier Signature Scheme
designated verifier signature bilinear pairings cryptanalysis
2009/6/5
In this paper, we present a universal forgery attack on Kang
et al.’s identity-based strong designated verifier signature (IBSDVS)
scheme. We show anyone can forge a valid IBSDVS on an arbitrary
me...
Identity Based Strong Designated Verifier Signature Scheme
Designated verifier signature Identity based signature Bilinear pairings
2008/11/13
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
