Security Arguments for Digital Signatures and Blind Signatures
Journal of Cryptology, 2000This paper proves the security of a large class of signature schemes in the so-called random oracle model. This model assumes that the hash function used in a signature scheme behaves as a random function. However, it has been shown that there exist (contrived) schemes that are provably secure in the random oracle model, but not when used with a real ...

Nominative Signature from Ring Signature
2007Since the introduction of nominative signature (NS) in 1996, there have been a handful of schemes proposed and almost all of them have been found flawed. The only one which is secure requires multiround of communications between the nominator and the nominee for signature generation. In this paper, we propose a novel construction which is efficient and

Ring Signature Based on ElGamal Signature
2006Ring signature was first introduced by Rivest, Shamir and Tanman in 2001. In a ring signature, instead of revealing the actual identity of the message signer, it specifies a set of possible signers. The verifier can be convinced that the signature was indeed generated by one of the ring members, however, he is unable to tell which member actually ...

A Signature Complexity Measure to Select Reference Signatures for Online Signature Verification
2015 International Conference of the Biometrics Special Interest Group (BIOSIG), 2015This paper presents an original procedure for selecting the reference online signature instances of a writer, an important issue for any effective signature verifier. To this end, for each signature instance, we propose a novel complexity measure, by exploiting a global description of signatures in the frequency domain as well as a global statistical ...

On the Signature Trees and Balanced Signature Trees
21st International Conference on Data Engineering (ICDE'05), 2005Advanced database application areas, such as computer aided design, office automation, digital libraries, data-mining as well as hypertext and multimedia systems need to handle complex data structures with set-valued attributes, which can be represented as bit strings, called signatures.

On Signatures and Authentication
1983The design of cryptographic protocols using trapdoor and one-way functions has received considerable attention in the past few years [1–8]. More recently, attention has been paid to provide rigorous correctness proofs based on simple mathematical assumptions, for example, in coin flipping (Blum [1]), mental poker (Goldwasser and Micali [4]).

If \(R\) is a ring with an identity and \(F\) is a field-like semigroup (i.e., a commutative semigroup with an identity element and a zero element such that \(F \backslash \{0\}\) is a group with a unique element \(-1\) of order 2) then a signature of \(R\) over \(F\) is a mapping \(\sigma : R \to F\) such that \(\sigma (-2) = - 1\), \(\sigma (ab ...
