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 ...

In 2006, Huang, Susilo, Mu and Zhang proposed the concept of restricted universal designated verifier signatures while Klonowski, Kubiak, Kutylowski and Lauks proposed independently the dual primitive of dedicated signatures. In both notions, a signature holder can convince one or more verifiers of his knowledge of a digital signature, but cannot exploit this knowledge without being punished fo...

Designated verifier signatures are intended to a specific and unique designated verifier, who is the only one person to check their validity. This paper proposes a new efficient non-delegatable strong designated verifier signature scheme based on identity based cryptography. We analyze the security of the scheme and compare its computational aspects with the other ID-SDVS schemes existing in li...

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 is just message authentication code HMAC. Without the key property, unforgeability, for signatures, these schemes cannot enable signers to have complete controls over their signatures as demanded by...

In a designated verifier signature (DVS) scheme a signer creates a signature which is only verifiable by a designated verifier. A DVS is a useful scheme for authenticating a signer without disturbing her privacy. In a universal DVS (UDVS) scheme, everyone who holds Alice’s traditional signature on a message (the signature holder), is able to transform it to a DVS for a specific verifier. Non-de...

In this paper, we propose a new type of digital signatures which is specifically designed for graph-based big data system. The properties of the proposed signatures are twofold. On one side it possesses the features of transitive signatures: One can sign a graph in such a way that, given two signatures on adjacent edges ði; jÞ and ðj; kÞ, anyone with public information can compute a signature o...

The notion of strong designated verifier signature was put forth by Jakobsson, Sako and Impagliazzo in 1996, but the formal definition was defined recently by Saeednia, Kremer and Markowitch in 2003 and revisited by Laguillaumie and Vergnaud in 2004. In this paper, we firstly propose the notion of short strong designated verifier signature scheme, and extend it to the short identity-based stron...

There are many cryptographic schemes with anonymity, such as group signatures. As one important property, anonymity revocation has been introduced. In such schemes, the fact of whether a signer’s rights have been revoked or not is important additional information. For example, if a third party knows that there are many revoked members in a company, then the company’s reputation may be damaged i...
